MAX485CPA+中文资料

For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .General DescriptionThe MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps.The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them to transmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consume only 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-load receiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, while the MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________ApplicationsLow-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level TranslatorsTransceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features♦For Fault-Tolerant ApplicationsMAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 TransceiverMAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers♦For Space-Constrained ApplicationsMAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 TransceiversMAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 PackageMAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe ReceiversMAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-855/RS-422 Transmitters ♦For Multiple Transceiver ApplicationsMAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters ♦For Fail-Safe ApplicationsMAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceivers♦For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kV ESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 TransceiversMAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________Selection Table19-0122; Rev 8; 10/03Ordering Information appears at end of data sheet.M A X 481/M A X 483/M A X 485/M A X 487–M A X 491/M A X 1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSSupply Voltage (V CC ).............................................................12V Control Input Voltage (RE , DE)...................-0.5V to (V CC + 0.5V)Driver Input Voltage (DI).............................-0.5V to (V CC + 0.5V)Driver Output Voltage (A, B)...................................-8V to +12.5V Receiver Input Voltage (A, B).................................-8V to +12.5V Receiver Output Voltage (RO).....................-0.5V to (V CC +0.5V)Continuous Power Dissipation (T A = +70°C)8-Pin Plastic DIP (derate 9.09mW/°C above +70°C)....727mW 14-Pin Plastic DIP (derate 10.00mW/°C above +70°C)..800mW 8-Pin SO (derate 5.88mW/°C above +70°C).................471mW14-Pin SO (derate 8.33mW/°C above +70°C)...............667mW 8-Pin µMAX (derate 4.1mW/°C above +70°C)..............830mW 8-Pin CERDIP (derate 8.00mW/°C above +70°C).........640mW 14-Pin CERDIP (derate 9.09mW/°C above +70°C).......727mW Operating Temperature RangesMAX4_ _C_ _/MAX1487C_ A...............................0°C to +70°C MAX4__E_ _/MAX1487E_ A.............................-40°C to +85°C MAX4__MJ_/MAX1487MJA...........................-55°C to +125°C Storage Temperature Range.............................-65°C to +160°C Lead Temperature (soldering, 10sec).............................+300°CDC ELECTRICAL CHARACTERISTICS(V CC = 5V ±5%, T A = T MIN to T MAX , unless otherwise noted.)

The MAX481, MAX485, MAX490,MAX491, and MAX1487 can transmit and receive at data rates up to 2.5Mbps, while the MAX483, MAX487,MAX488, and MAX489 are specified for data rates up to 250kbps. The MAX488–MAX491 are full-duplex trans-ceivers while the MAX481, MAX483, MAX485, MAX487,and MAX1487 are half-duplex. In addition, Driver Enable (DE) and Receiver Enable (RE) pins are included on the MAX481, MAX483, MAX485, MAX487, MAX489,MAX491, and MAX1487. When disabled, the driver and receiver outputs are high impedance.MAX487/MAX1487:128 Transceivers on the BusThe 48k Ω, 1/4-unit-load receiver input impedance of the MAX487 and MAX1487 allows up to 128 transceivers on a bus, compared to the 1-unit load (12k Ωinput impedance) of standard RS-485 drivers (32 trans-ceivers maximum). Any combination of MAX487/MAX1487 and other RS-485 transceivers with a total of 32 unit loads or less can be put on the bus. The MAX481/MAX483/MAX485 and MAX488–MAX491 have standard 12k ΩReceiver Input impedance.Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 8_______________________________________________________________________________________Figure 2.

ReceivingLow-Power Shutdown Mode (MAX481/MAX483/MAX487)A low-power shutdown mode is initiated by bringing both RE high and DE low. The devices will not shut down unless both the driver and receiver are disabled.In shutdown, the devices typically draw only 0.1µA of supply current.RE and DE may be driven simultaneously; the parts are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the parts are guaranteed to enter shutdown.For the MAX481, MAX483, and MAX487, the t ZH and t ZL enable times assume the part was not in the low-power shutdown state (the MAX485/MAX488–MAX491and MAX1487 can not be shut down). The t ZH(SHDN)and t ZL(SHDN)enable times assume the parts were shut down (see Electrical Characteristics ).It takes the drivers and receivers longer to become enabled from the low-power shutdown state (t ZH(SHDN ), t ZL(SHDN)) than from the operating mode (t ZH , t ZL ). (The parts are in operating mode if the –R —E –,DE inputs equal a logical 0,1 or 1,1 or 0, 0.)Driver Output ProtectionExcessive output current and power dissipation caused by faults or by bus contention are prevented by two mechanisms. A foldback current limit on the output stage provides immediate protection against short cir-cuits over the whole common-mode voltage range (see Typical Operating Characteristics ). In addition, a ther-mal shutdown circuit forces the driver outputs into a high-impedance state if the die temperature rises excessively.Propagation DelayMany digital encoding schemes depend on the differ-ence between the driver and receiver propagation delay times. Typical propagation delays are shown in Figures 15–18 using Figure 14’s test circuit.The difference in receiver delay times, | t PLH - t PHL |, is typically under 13ns for the MAX481, MAX485,MAX490, MAX491, and MAX1487 and is typically less than 100ns for the MAX483 and MAX487–MAX489.The driver skew times are typically 5ns (10ns max) for the MAX481, MAX485, MAX490, MAX491, and MAX1487, and are typically 100ns (800ns max) for the MAX483 and MAX487–MAX489.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________1110dB/div0Hz5MHz500kHz/div10dB/div0Hz5MHz500kHz/divFigure 12.

These parts can also be used as line repeaters, with cable lengths longer than 4000 feet, as shown in Figure 23.To minimize reflections, the line should be terminated at both ends in its characteristic impedance, and stub lengths off the main line should be kept as short as possi-ble. The slew-rate-limited MAX483 and MAX487–MAX489are more tolerant of imperfect termination.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________13DIV Y -V ZRO5V 0V1V0V -1V5V 0V2µs/divFigure 19.

General DescriptionThe MAX481, MAX483, MAX485, MAX487–MAX491, andMAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and onereceiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize E MI andreduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps.The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them totransmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA ofsupply current when unloaded or fully loaded with disableddrivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consumeonly 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protectedagainst excessive power dissipation by thermal shutdowncircuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature thatguarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-loadreceiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, whilethe MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________Applications Low-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level Translators Transceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features o For Fault-Tolerant Applications MAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 Transceiver MAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers o For Space-Constrained Applications MAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 Transceivers MAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 Package MAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe Receivers MAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-485/RS-422 Transmitters o For Multiple Transceiver Applications MAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters o For Fail-Safe Applications MAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceiverso For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kVESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 Transceivers For pricing, delivery, and ordering information, please contact Maxim Direct at1-888-629-4642, or visit Maxim Integrated’s website at .______________________________________________________________Selection Table19-0122; Rev 10; 9/14PARTNUMBERHALF/FULL DUPLEX DATA RATE (Mbps) SLEW-RATE LIMITED LOW-POWER SHUTDOWN RECEIVER/DRIVER ENABLE QUIESCENT CURRENT (μA) NUMBER OF RECEIVERS ON BUS PIN COUNT MAX481Half 2.5No Yes Yes 300328MAX483Half 0.25Yes Yes Yes 120328MAX485Half 2.5No No Yes 300328MAX487Half 0.25Yes Yes Yes 1201288MAX488Full 0.25Yes No No 120328MAX489Full 0.25Yes No Yes 1203214MAX490Full 2.5No No No 300328MAX491Full 2.5No No Yes 3003214MAX1487 Half 2.5No No Yes 2301288Ordering Information appears at end of data sheet.找电子元器件上宇航军工MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-LimitedRS-485/RS-422 TransceiversPackage Information For the latest package outline information and land patterns, go to .

155H学习资料硬件部分

155H学习资料-----硬件部分1.155/622H是华为公司生产的集成式光网络设备，全称为Optix 155/622H(Metro1000)注：155/622H中为什么有622呢，主要原因是该设备最高支持622M的光板。

Metro1000中的Metro是指该设备支持以太网业务。

2.155/622H设备有两种电源模块，位置在设备的最右边（在后面看，以后如果不标注前后的话，都为后面位置），主要有-48V和+24V两种，在-48V设备中有部分在电源模块处标识-48V，有部分不标识，如果碰到没标识的设备，都是-48V的设备；+24V的设备都有标识。

3.155/622H设备的开关在电源模块的上部，标有ON/OFF，注意如果此站开通业务请注意不要乱动开关，以免业务中断。

4.155/622H设备总有两路供电接口，上面的为第一路，下面的第2路，但考虑每个机房只有一路供电系统，一般只提供一路。

5.在每一个供电模块供电接口处都标有一些标识，其中PGND表示为保护地（保护地线一般都是黄绿相间或黄色的线），BGND表示为工作地（工作地一般都是黑色，如果为-48V 设备则为+，如果为+24V设备则为-），-48V表示接空开或保险丝的那根线（一般都是用蓝色表示），+24V表示接空开或保险丝的那根线（一般都是用红色表示）。

6.在电源模块的右边有一个小把手的地方是过滤网的地方，一般按要求一个月或两个月拿出来清洗一下，请注意保持清洁。

清洁方法为把过滤网拔出后用清水洗净，晾干后重新插入即可。

7.在一般情况下，-48V电可供给华为的所有155/622H设备（即可供给-48V和+24V使用），但此种情况只允许在应急情况下使用，平时不得混用。

并且+24V的电源模块可安放在-48V设备上，同样-48V电源模块也可放置在+24V设备上（可以互换）。

8.在设备的最左边为风扇位置，上面带有一个可插“防静电手腕”的小孔，边上有防静电标识。

9.单板位置如下：10.单板介绍:OI2S:单光口STM-1（155M）光板，今年在各县市均未出现，但在市区出现过，跟OI2D 一样，只是只有一个光口。

To start the MAX16826 EV kit software, click Start | Programs | Maxim MAX16826 Evaluation Kit | Maxim MAX16826 Evaluation Kit that is created during installation. The GUI main window appears as shown in Figure 1.Figure 1. MAX16826 EV Kit Software Main WindowString Current SetThe String Current Set group box is located at the upperleft corner of the main window. Use the scrollbars toadjust the current of the LED strings. The correspondingvalues of the current will be shown in the adjacent editboxes. Press the Read button to read the values from thelinear regulator output registers of the MAX16826. Theequivalent values of the output current will be shown inthe edit boxes.Boost Output ControlThe Boost Output Control Mode group box has thefunctions to control the boost output voltage.To control the boost output voltage manually, click on theradio button next to the Manual Control group box. Usethe scrollbar to adjust the output voltage, and the volt-age value will be displayed in the adjacent edit box. Theactual boost output voltage can be seen in the Read BackValues group box.To use the software automatic control, click on the radiobutton next to the Software Control group box. The editbox next to the Set button is used to change the Drain toGND regulated voltage of the current sink FETs on the LEDstring with the highest voltage drop. This voltage setting willdepend on how much overhead the user is willing to have.If the set value is too low, the LED currents will no longerbe well regulated and may indeed drop because the boostvoltage might fall too low. The scrollbar in this mode willmove automatically to compensate and regulate the outputvoltage. The update rate is approximately once per second.In any case, the channel with the lowest voltage across thesink FET will be regulated to the value in the edit box. DIM Pulse Width Modulation (DPWM)The DPWM group box is located at the center of the mainwindow. The four DIM PWM signals generated by theon-board MAXQ2000 microcontrollers are used to controlthe brightness of the LEDs. Adjust the scrollbars in theDPWM Duty Cycle group box to change the duty cycles of the PWM signals and the values of the duty cycle (%)are shown in the adjacent edit boxes. Check the Set AllChannels to 100% Duty Cycle checkbox to force all channel duty cycles to 100%.In the DPWM Frequency group box, change the DPWMfrequency by adjusting the scrollbar position and pressthe Set button. The frequency value will be shown in theedit box.To guarantee that the leading edge of all the DIM signalsare synchronized, press the Set button in the DPWMFrequency group box.Press the Start button to start to generate the PWM signals.Press the Stop button to stop all PWM signals.StatusThe Status group box is located at the right of the main window. The software reads the external FET drain voltage measurements, and the boost output voltage measurement from the ADC output registers of the MAX16826. The software multiplies the measured values by the appropriate scaling factor and then displays them in the Read Back Values group box.Enter the values into the edit boxes in the Fault Level Set group box to set the fault-detection values. When the value in the Read Back Values group box is less than the fault-detection value, then the color of the read-back value changes to dark green. When the read-back value is 0 to 10% higher than the fault-detection value, the read-back value turns a lime color. If the read-back value is more than 10% higher than the fault-detection value, then the read-back value turns purple. The read-back value turns red when it is more than 20% higher than the fault-detection value.The software also reads the fault register to detect the fault conditions. If a fault condition exists, it will be shown in the String Fault Status group box. See Table 2 for the fault-condition explanations.Press the Read button to update the Status group box. By checking the Automatic Read checkbox, the Status group box will be automatically updated every second. Enable/DisableThe Enable/Disable group box controls the signal on the SYNC/EN pin. Click on the Enable radio button to set the signal high and enable the MAX16826. Click on the Disable radio button to set the signal low and disable the MAX16826.StandbyCheck the Standby checkbox to set the MAX16826 to standby mode. Refer to the MAX16826 IC data sheet for more information regarding standby mode.Table 2. Fault Conditions*Open LED string detection may require multiple flag examination. FAULT NAME CONDITIONTOADC conversion timeout; alsocorresponds to open string condition* Open LED string openShort LED string shortedOVP OvervoltageScaling FactorsThe calculations for the LED string current, boost output voltage, and the read-back values are based on the scal-ing factors. You can change the scaling factor by select-ing the Scaling Factor menu item under the Scaling Factors menu bar. In the pop-up window shown in Figure 2, enter the appropriate scaling factor.See Table 3 for the formulas for the scaling factors.

This EV kit consists of a controller board and an LED driver board. The break-away slots at the center of the EV kit make it easier for the user to break and separate the controller board from the LED driver board. This is done so that once the evaluation is complete with the included software, the driver board can easily be used in the target application environment with the target system microcontroller.To connect the power, ground, PWM, and the I2C inter-face signals of the boards, attach the ribbon cable to the P1 connector of the controller board and attach the other end of the ribbon cable to the P2 connector of the LED driver board.Controller BoardThe controller board acts as the bridge between the soft-ware in the PC and the actual LED driver board containing the MAX16826. In addition to the USB connectivity, it gen-erates the four adjustable PWM DIM signals that control the brightness of the LEDs. The controller board com-municates with the driver board through the I2C interface, and is able to read or change the values of the registers in the MAX16826.The user can use the MAX16826 evaluation kit software to control the controller board.See Table 1 to control the MAX16826 with a user-supplied PWM signal.LED Driver BoardThe LED driver board is able to drive up to four LED strings (7 LEDs/string). LED strings can be connected to the LED driver board through the P3 connector by using a ribbon cable. Connect all of the anode ends of the LED strings to the P3-1 pin (which connects to the boost out-put) of the P3 connector. Then connect the cathode ends of the LED strings to the P3-2 to P3-5 pins (that connects to the drains of the sink FETs) of the P3 connector. User-Supplied I2C InterfaceTo use the MAX16826 EV kit with a user-supplied I2C interface, install the shunts on pins 2-3 of JU4 and JU5. Connect SDA, SCL, and GND lines from the usersupplied I2C interface to the SDA, SCL, and PGND pads on the MAX16826 controller board.After the LED driver board has broken away from the controller board, the user may connect their supplied I2C, DIM, and power signals to the LED driver board through the P2 connector using a ribbon cable. See Table 4 for the pin description of the P2 connector.Table 4.

General DescriptionThe MAX481, MAX483, MAX485, MAX487–MAX491, andMAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and onereceiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize E MI andreduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps.The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them totransmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA ofsupply current when unloaded or fully loaded with disableddrivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consumeonly 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protectedagainst excessive power dissipation by thermal shutdowncircuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature thatguarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-loadreceiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, whilethe MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________Applications Low-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level Translators Transceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features o For Fault-Tolerant Applications MAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 Transceiver MAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers o For Space-Constrained Applications MAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 Transceivers MAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 Package MAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe Receivers MAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-485/RS-422 Transmitters o For Multiple Transceiver Applications MAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters o For Fail-Safe Applications MAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceiverso For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kVESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 Transceivers For pricing, delivery, and ordering information, please contact Maxim Direct at1-888-629-4642, or visit Maxim Integrated’s website at .______________________________________________________________Selection Table19-0122; Rev 10; 9/14PARTNUMBERHALF/FULL DUPLEX DATA RATE (Mbps) SLEW-RATE LIMITED LOW-POWER SHUTDOWN RECEIVER/DRIVER ENABLE QUIESCENT CURRENT (μA) NUMBER OF RECEIVERS ON BUS PIN COUNT MAX481Half 2.5No Yes Yes 300328MAX483Half 0.25Yes Yes Yes 120328MAX485Half 2.5No No Yes 300328MAX487Half 0.25Yes Yes Yes 1201288MAX488Full 0.25Yes No No 120328MAX489Full 0.25Yes No Yes 1203214MAX490Full 2.5No No No 300328MAX491Full 2.5No No Yes 3003214MAX1487 Half 2.5No No Yes 2301288Ordering Information appears at end of data sheet.找电子元器件上宇航军工MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-LimitedRS-485/RS-422 TransceiversPackage Information For the latest package outline information and land patterns, go to .

aeon跑步机型号A155说明书心率测试分类：手握心率和无线心率带。

手握心车的弊端，手握心车测试人在运动时，身体在不停的运动血液传感信号波动大其测量的数据精准度比较低，手握心率传感对环境气候的要求比较高，在不同温度湿度环境测量的心率值是不同的。

无线心车带的准确性，由于心车带直接放置在胸口上，其检测的准确性比较高也可以实时测量心车，心车带内含的电极片采集人体内的的心脏电波（如同医院的心电图测试传感原理）是心车测重的最为淮确的方法，再通过无线传输技术发送到电子表盘上，更有效地提醒运动监视对象控制心车运动心率，即人体在运动时保持的心率状态。

不管是懂跑，还是快跑。

都有一个合适的心车才能达到较佳的运动效果。

保持最佳运动心率对于运动效果和运动安全都很重要，三高人群锻炼中尤为重要的是运动心车，如果心车过高，会对身体健康不利，导致恶心、头量、胸闷，糖尿病患者则会使血糖急剧降低，而且减脂效果也不好，心车低对身体没有危害，但是锻炼效果不好。

The maximum diameter reduction is proportional to the open “ear” width. The theoretical maximum reduction in diameter is given by the formula:To ensure perfect sealing, clamp ears must be correctly closed during installation.Clamp diameterThe following applies as a guideline: To determine the correct clamp diameter, push the hose onto the attaching material, (e.g.the nipple), and then measure the outer diameter of the hose.The value of the outer diameter must be slightly above the average value of the diameter range of the clamp to be selected.Mechanical interlockThe mechanical interlock is a mechanical connection which keeps the clamp securely closed. By using a mechanical interlock instead of spot-welding, corrosion around the closure elements is reduced.Max. diameter reduction =Ear width (s)πInstallation dataSize Closing Installation tools force-monitored1:(mm) force max.

To ensure optimum clamp selection, we recommend making functional tests with several assemblies.Assembly recommendationsThe clamp ear should be closed with a constant tool jaw force, this practice is referred to as “force priority closure”. This assembly method ensures that a uniform and repeatable stress is applied to the application with a constant tensile force on the mechanical interlock.Employing this methodology when closing 105 & 155 series clamps will compensate for any component tolerance variations, and ensure that the clamp applies a constant radial force to the application. Fluctuations in component tolerances are absorbed by variations in the “ear” gap (the space between the lower radii after installation).Closing forceIt is important to realize that there is in a very close relationship between the desired compression of the material being clamped and the closing force selected. The table below gives maximum closing forces in relation to the size of the part being clamped.
