308DUO充电器使用手册
建武TK308说明书
TK-308／208对讲机的功能调整TK-308/208对讲机是一款功能多、体积小、功率大、收信灵敏度高的手持机。
但机器调整麻烦，资料少。
本文介绍一下对讲机在使用中必不可少的两种功能。
这两种功能不在菜单中显示，而是在面板上，即功能键的双音多频码的缩位储存、提取及无线复制调整功能。
具体调整步骤如下：一、双音多频码的缩位储存及提取例如对12345双音多频码缩位储存、提取的方法如下。
1．储存：首先按DIAL键(必须在用户使用状态或在维修状态)，屏幕上出现“P”标志；再按MONI键屏幕上出现“P…”标志；便可按12345数字键，屏幕上也陆着显示12345数字；随后再先按DIAL键，最后按要求缩位到某个数字的键。
如果按1键，便把12345缩位完毕。
2。
提取：按DIAL键，屏幕上出现“P”标志；再按数字1键，便把储存的缩位码提取出来，如果要把缩位码发射出去，则按住FIT键，同时先按DIAL键，再按数字1键即完成。
缩位码最多可存10组15位码。
二、无线复制功能调整此功能为大量复制带来了方便。
具体操作如下：1．先将一台TK-308 UHF频段机器调整资料输入完毕，处于频率设定模式；并调一个固定的频率，如450.00MHz，设为A机。
2．调整的B、C…N台机器也处于频率设定模式。
屏显频率与A机相同，即450.00MHz。
3．将设置好的A机与被调整的B、C…N台机全部关闭；并把每台机器按住LOW键开机，屏显为CLONE标志，便处于复制状态。
4．将A机按一下PTT键，A机便把机内资由无线电波以双音频的形式复制给其他机器。
若屏显为“Err”标志，则复制完毕。
将全部机器关闭，对每个机器按住REV键同时开机，便可处于用户使用模式使用了。
一、模式：该机有三大模式即频率设置模式、维修模式和用户使用模式，进行功能设置时应先进入频率设置模式。
1．频率设定模式：在这个模式中，可设定各信道的频率，还可以设定各种功能和工作参数。
此模式下，每当接通电源时，可以看到LCD屏显示有频率数，但是不能接收和发射。

建武308说明手册
建武308说明书一、3大状态模式及转换。
１、频率设定模式。
在这个模式中，可以设定各信道的频率，还可以设定各种功能和工作参数。
每当接通电源时，可以看到“LCD”屏显示有频率数，但不能进行接收和发射信号。
进入该模式的方法是：“REV”键，同时接通电源，能够从频率设定模式转换为该模式，但对讲机所有存储信道未设定频率数据即全空信道时，不能进入该模式。
二、各操作键在３大状态模式下功能作用。
如下图。
三、功能参数设置。
１、进入菜单模式。
在频率设定模式状态下，关闭电源，按住“SCAN”键，同时接通电源即可。
此时，“LCD”屏右上角显示功能序号“N001”，中央部分显示功能待定值。
２、改变功能序号，设置参数。
用“ENC/SQL”旋钮从“N001”开始改变功能序号，顺时针方向旋转，序号增大，反之减小。
用“LOW”键设置功能参数，每按一次，参数值就变化一次。
３、退出菜单模式。
按住“ENC/SQL”旋钮和“LOW”键以外的任意键或关闭电源均可退出菜单模式而回到频率设定模式。
的右上部出现闪烁的信道号“04”后，同时按“CSET”和“PTT”键，屏显157.90，至此，在4信道设定发射频率完成。
２、检查指定信道的频率参数。
按“RVE”键，“LCD”屏中央显示接收频率163.60MHZ，右上部显示信道号码“04”。
当接收频率和发射频率已设定，则频显的前面有“F”标志。
按“CSET”，在“F”标志前出现“R”符号，则显示的为发射频率，再按“CSET”，“R”符号消失，则显示的频率为接收频率，按“DIAL”键，则显示“CTC”频率。
３、消除指定信道的设定数据。
在设定了各信道数据的状态下，可转动“ENC/SQL”旋钮选择出要消除的信道号码和频率显示在“LCD”屏上，按“LOW”，则该信道的设定数据被消除，回到频率设定模式，但除该信道外的其它信道数据依然有效。
五、编码静噪功能的设定。
TK-208型对讲机有一个用于编码静噪功能的“DTMF”号码即自动台号码，该号码由３１、关闭电源，按住“DIAL”键，同时接通电源，可从频率设定模式进入静噪阀值电平设置状态，可先关闭电源，按住“REV”键，同时接通电源即可。

308使用
健伍308使用方法一、频率范围: ;TK208:150MHZ;TK308:450MHZ二、本机程序主要采用三大模式:频率设定模式;维修模式;用户模式.1.频率设定模式:在这个模式中,可设定各信道的频率,还可以设定各种功能和工作参数,打开电源,虽然可以看到显示频率,但是不能接收和发射.如:***•**2.维修模式:在这个模式中,显示屏显示频率数值,可以进行接收和发射.如:一***•**3.用户模式:这个模式是用户通常使用的模式,打开电源显示屏显示存储信道号码,在这个模式中可以使用的功能是在频率设定模式中所设定的.如:CH*三、本机出厂状态:打开电源,便进入频率设定模式,必须在此模式下设定信道和功能后,才可以进入用户模式使用.四、设定信道:1.选定频率:开机进入频率模式,首先对频率进行选择.按一下MONI键,有光标"一"闪烁,旋编码开关,频率以"MHZ"为单位增减,再接一次MONI键光标消失,旋编码开关,频率以" KHZ"为单位增减,选定所需要的频率.2.频率写入信道:按一次"CSET"键,出现**闪烁,旋编码开关,选择所需要的信道(信道范围00-39,再按一次"CSET"键,闪烁消失,这时接收频率已写入所选择的信道;按方法1选定发射频率,按一次"CSET"键,出现"*闪烁,同时按PTT和CSri键,闪烁消失,这时发射频率已写入所选择的信道.(注:如某一信道接收频率未写或未写进,发射频率就不能写入.)3.确认频率写入:在频率模式下,按REV键,显示±显示内容为接收频率及信道号码,再按"CEST"键,显示R±显示内容为发射频率及信道号码以上两次确认说明信道的接收和发射都已设定,如设定两个或两个以上信道,旋编码开关,所写入频率及信道将显示出来.四、模式之间相互转换1.出厂状态时,打开电源就进入频率设定模式.2.关闭电源,按PTT键和CTCSS键,同时打开电源,便进入了维修模式,重复此操作,便返回到频率模式.3.频率模式设定了信道,关闭电源,按REV键,同时打开电源,即可进入用户模式.4.用户模式回到频率模式:关闭电源,取下后壳上的两个螺钉.打开机壳,在控制板的右上部把印有" CH OFF'标志处暂时短路,同时打开电源即可.(附图一所示)五、消除己在信道中设定的数据1.对讲机变为确认数据状态±转动编码旋钮选择想要消除的信道.2.显示屏上显示要消除的信道后,按LOW键,所选择的信道立即消除,返回到频率设定模式. 注:*代表频率及信道号码数字.警告:以上内容是用户可操作范围,超出设置范围的内容必须经过重新调试,否则会引起您的对讲机有些功能工作不正常,严重会导致对讲机无法工作.TK308手持机的扩频与特殊功能的实现一、扩颊的实现:TK308为专业型手持对讲机,故频率范围分高段与低段,即400~420MHz、450~470MHz两频段.因频段较窄,业余无线电爱好者若想扩频可采用以下方法:与TK308同时出品的TH42为业余型全频段手机(400~470MHz),其外形、内部电路极相似,且都有无线复制功能.虽然无线复制功能为同一型号机器间才可进行,但实践证明,对同一品牌的型号相近(尤其是微机相似)的机器间也可进行部分复制.TK308的扩频即可利用其无线复制功能,将TH42调至某一频率(如450MHz)处使之处于无线复制状态,再将TK308置于频率设定状态模式,其频率也调至450MHz,按住LOW键开机后,将显示"CLONE,表明巳进入无线复制状态;然后按下TH42的PTT犍,此时复制开始.TK308显示屏右上角数字从"00"开始往上一秒一秒地显示,一般进行38—50s,会出现"Error" (信息出错).此时可关机回到频率设定状态(出现"Error"后微机不再接受夏制),可看到原来TH42中的频率巳存人TK308,稍作改动即可使用.采用此法对TK308进行扩频,因对450~470MHz频率段各项指标较好(对高段机而言).若扩频到低段,灵敏度有所下降.但实践证明在400~450MHz之间灵敏度下降不多,但低于400MHz则下降较多.另须注意,扩频后的高段机,低于450MHz不能发射,只能接收,故可使机器在高段发射,低段接收,这样可增加通话联络时的保密性.二、特殊功能的实现、使用TK308有方便的26功能菜单可供选择,其中除了常规功能外,尚有一些特殊功能鲜为人知: 1.信号强度计的调整功能.此功能未在菜单中列出,且为TK308独有.TK308的信号强度计的显示有三种方式:①按信号强弱以2格为步进;②按信号强弱以4格为步进;③有信号全显示/无信号静噪无显示.以上三种方式可任选使用.选择时先打开后盖,在控制板上可看到两组焊点,其中一组标有"SM"即为强度计调整设置点.在"SM"处用导线连接后开机,显示屏显示"S-SET".然后用"MONI"键选择显示方式,用"LAMP"键调整强度计末端灵敏度,最后关机重新开机即可.2.频率步进的调整.菜单中的功能4为扫描频率步进率选择,选5kHz或12.5kHz,若想选25kHz(使用较多)时,可通过上述无线复制方法进行复制即可.此后菜单中将显示"00.5".3.自动回铃功能.当收到正确编码,能发出一串振铃音给对方,使用时使功能8处于"ON",功能15处于"1"即可.4.空号功能.此机"D"健除手动拨号外其余均作空号使用,用于开机码与呼叫码(或电话号码)间的延时,以便中继器的打开、应答,可以在1~16s间选择.一般选"1"为好.其他功能17、18为发射音频的长短快慢选择,时间在50~200ms间选.功能19为发射前延时时间调整(100~850ms).其它功能为常规功能,此处从略.TK-308/208对讲机的功能调整TK-308/208对讲机是一款功能多、体积小、功率大、收信灵敏度高的手持机.但机器调整麻烦,资料少.本文介绍一下对讲机在使用中必不可少的两种功能.这两种功能不在菜单中显示,而是在面板上,即功能键的双音多频码的缩位储存、提取及无线复制调整功能.具体调整步骤如下:一、双音多频码的缩位储存及提取例如对12345双音多频码缩位储存、提取的方法如下.1.储存:首先按DIAL键(必须在用户使用状态或在维修状态),屏幕上出现"P"标志;再按MONI 键屏幕上出现"P…"标志;便可按12345数字键,屏幕上也陆着显示12345数字;随后再先按DIAL键,最后按要求缩位到某个数字的键.如果按1键,便把12345缩位完毕.2.提取:按DIAL键,屏幕上出现"P"标志;再按数字1键,便把储存的缩位码提取出来,如果要把缩位码发射出去,则按住FIT键,同时先按DIAL键,再按数字1键即完成.缩位码最多可存10组15位码.二、无线复制功能调整此功能为大量复制带来了方便.具体操作如下.1.先将一台TK-308 UHF频段机器调整资料输入完毕,处于频率设定模式;并调一个固定的频率,如450.00MHz,设为A机.2.调整的B、C…N台机器也处于频率设定模式.屏显频率与A机相同,即450.00MHz.3.将设置好的A机与被调整的B、C…N台机全部关闭;并把每台机器按住LOW键开机,屏显为CLONE标志,便处于复制状态.4.将A机按一下PTT键,A机便把机内资由无线电波以双音频的形式复制给其他机器.若屏显为"Err"标志,则复制完毕.将全部机器关闭,对每个机器按住REV键同时开机,便可处于用户使用模式使用了.TK208/308对讲机的功能调整TK208/308对讲机是一种超小型多功能专业型手机,正常工作时采用频道显示,具有较好保密性.但该机功能设置方法较为特殊且有关资料又少,一旦功能及频率丢失只能送经销处,甚为不便,现在向大家介绍TK208/308对讲机的功能设置方法:一、模式:该机有三大模式即频率设置模式、维修模式和用户使用模式,进行功能设置时应先进入频率设置模式.二、如何进入频率设置模式:打开后盖,将CH OFF点短接同时打开电源,此时进入频率设定模式,暂时关闭电源,按住SCAN同时打开电源,显示屏右上角显示NO1(功能序号),进入功能设置模式.功能设置如表所示:功能表中各参数的设定方法如下:利用频道选择钮、对照功能设置表,选好某一功能后,利用高低功能转换键设定功能参数,每按一下其功能设定值就变化一次.三、如何恢复到使用模式:功能设置完成后,关闭电源再打开电源,机器由功能菜单模式进入频率设置模式,又暂时关闭电源,按住REV键同时打开电源,机器进入用户使用模式.序号功能名称初始值选择范围1 电池省电功能ON ON或OFF2 "嘟嘟"音提示功能ON ON或OFF3 监听功能OFF ON或OFF4 频率步进值(V)5KHz (U)12.5KHz 5KHz或12.5KHz5 TO/CO扫描方式TO TO/CO6 TO扫描时的延迟时间5s 1.0~16s7 CTCSS功能OFF ON或OFF8 编码静噪功能OFF ON或OFF9 编码静噪关闭延迟时间选择10s 1.0~16s10 群呼"王码"选择OFF OFF、A、B、C、D、E、F11 禁发功能ON ON或OFF12 发射定时器900s 900s、30s、60s、90s13 编码与CTCSS同时设置时,静噪开启条件ON ON或OFF14 音频报警功能ON ON或OFF15 自动应答及应答方式选择OFF ON或OFF16 AN1功能及发射时机选择OFF OFF、按下、松开PTT17 DTMF码宽选择50ms 50ms~200ms18 DTMF码间间隔选择50ms 50ms~200ms19 首位DTMF码发出延迟时间100ms 100~850ms20 设置CTCSS时首位DTMF码发出延迟时间100ms 100~850ms21 重拨号功能ON ON或OFF22 缩位拨号功能ON ON或OFF23 自动发出DTMF码功能ON ON或OFF24 16制式键盘选择ON ON或OFF25 倒频功能ON ON或OFF以上是TK208、TK308对讲机的调整方法.1．信号强度计的调整功能。

MAX3080-MAX3089高速RS-485 RS-422通信传输器说明说明书
EVALUATION KIT AVAILABLEGeneral DescriptionThe MAX3080–MAX3089 high-speed transceivers for RS-485/RS-422 communication contain one driver and one receiver. These devices feature fail-safe circuitry,which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance).The MAX3080/MAX3081/MAX3082 feature reduced slew-rate drivers that minimize EMI and reduce reflec-tions caused by improperly terminated cables, allowing error-free data transmission up to 115kbps. The MAX3083/MAX3084/MAX3085 offer higher driver out-put slew-rate limits, allowing transmit speeds up to 500kbps. The MAX3086/MAX3087/MAX3088’s driver slew rates are not limited, making transmit speeds up to 10Mbps possible. The MAX3089’s slew rate is selectable between 115kbps, 500kbps, and 10Mbps by driving a selector pin with a single three-state driver.These transceivers typically draw 375µA of supply current when unloaded, or when fully loaded with the drivers disabled.All devices have a 1/8-unit-load receiver input imped-ance that allows up to 256 transceivers on the bus. The MAX3082/MAX3085/MAX3088 are intended for half-duplex communications, while the MAX3080/MAX3081/MAX3083/MAX3084/MAX3086/MAX3087 are intended for full-duplex communications. The MAX3089 is selec-table between half-duplex and full-duplex operation. It also features independently programmable receiver and transmitter output phase via separate pins.Next Generation Device Features♦For Fault-Tolerant Applications:MAX3430: ±80V Fault-Protected, Fail-Safe, 1/4-Unit Load, +3.3V RS-485 Transceiver ♦For Low-Voltage Applications:MAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 Package ♦For Multiple Transceiver Applications:MAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad, RS-422 TransmittersMAX3040–MAX3045: ±10kV ESD-Protected, Quad,+5V, RS-485/RS-422 TransmittersApplicationsRS-422/RS-485 Communications Level TranslatorsTransceivers for EMI-Sensitive Applications Industrial-Control Local Area NetworksSlew-Rate-Limited RS-485/RS-422 TransceiversOrdering Information continued at end of data sheet.MAX3080–MAX3089Fail-Safe, High-Speed (10Mbps),Slew-Rate-Limited RS-485/RS-422 TransceiversABSOLUTE MAXIMUM RATINGSDC ELECTRICAL CHARACTERISTICS(V CC = +5V ±5%, T A = T MIN to T MAX , unless otherwise noted.

MAX3080/MAX3083/MAX3086 Pin Configuration and Typical Full-Duplex Operating CircuitFigure 2. MAX3081/MAX3084/MAX3087 Pin Configuration and Typical Full-Duplex Operating CircuitDetailed Description The MAX3080–MAX3089 high-speed transceivers for RS-485/RS-422 communication contain one driver and one receiver. These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all drivers disabled (see Fail-Safe section). The MAX3080/ MAX3081/MAX3082 feature reduced slew-rate drivers that minimize E MI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 115kbps (see Reduced EMI and Reflections section). The MAX3083/MAX3084/MAX3085 offer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX3086/ MAX3087/MAX3088’s driver slew rates are not limited, making transmit speeds up to 10Mbps possible. The MAX3089’s slew rate is selectable between 115kbps, 500kbps, and 10Mbps by driving a selector pin with a three-state driver.The MAX3082/MAX3085/MAX3088 are half-duplex transceivers, while the MAX3080/MAX3081/MAX3083/ MAX3084/MAX3086/MAX3087 are full-duplex trans-ceivers. The MAX3089 is selectable between half- and full-duplex communication by driving a selector pin high or low, respectively.All of these parts operate from a single +5V supply. Drivers are output short-circuit current limited. Thermal shutdown circuitry protects drivers against excessive power dissipation. When activated, the thermal shut-down circuitry places the driver outputs into a high-impedance state.Receiver Input Filtering The receivers of the MAX3080–MAX3085, and the MAX3089 when operating in 115kbps or 500kbps mode, incorporate input filtering in addition to input hysteresis. This filtering enhances noise immunity with differential signals that have very slow rise and fall times. Receiver propagation delay increases by 20% due to this filtering.Slew-Rate-Limited RS-485/RS-422 TransceiversFigure 4. MAX3089 Pin Configuration and Functional DiagramFail-Safe The MAX3080 family guarantees a logic-high receiver output when the receiver inputs are shorted or open, or when they are connected to a terminated transmission line with all drivers disabled. This is done by setting the receiver threshold between -50mV and -200mV. If the differential receiver input voltage (A-B) is greater than or equal to -50mV, RO is logic high. If A-B is less than or equal to -200mV, RO is logic low. In the case of a terminated bus with all transmitters disabled, the receiver’s differential input voltage is pulled to 0V by the termination. With the receiver thresholds of the MAX3080 family, this results in a logic high with a 50mV minimum noise margin. Unlike previous fail-safe devices, the -50mV to -200mV threshold complies with the ±200mV EIA/TIA-485 standard.MAX3089 Programming The MAX3089 has several programmable operating modes. Transmitter rise and fall times are programma-ble between 2500ns, 750ns, and 25ns, resulting in maximum data rates of 115kbps, 500kbps, and 10Mbps, respectively. To select the desired data rate, drive SRL to one of three possible states by using a three-state driver, by connecting it to V CC or GND, or by leaving it unconnected. For 115kbps operation, set the three-state device in high-impedance mode or leave SRL unconnected. For 500kbps operation, drive SRL high or connect it to V CC. For 10Mbps operation, drive SRL low or connect it to GND. SRL can be changed during operation without interrupting data communications.Occasionally, twisted-pair lines are connected back-ward from normal orientation. The MAX3089 has two pins that invert the phase of the driver and the receiver to correct for this problem. For normal operation, drive TXP and RXP low, connect them to ground, or leave them unconnected (internal pulldown). To invert the dri-ver phase, drive TXP high or connect it to V CC. To invert the receiver phase, drive RXP high or connect it to V CC. Note that the receiver threshold is positive when RXP is high.The MAX3089 can operate in full- or half-duplex mode. Drive the H/F pin low, leave it unconnected (internal pulldown), or connect it to GND for full-duplex opera-tion, and drive it high for half-duplex operation. In full-duplex mode, the pin configuration of the driver and receiver is the same as that of a MAX3080 (Figure 4). In half-duplex mode, the receiver inputs are switched to the driver outputs, connecting outputs Y and Z to inputs A and B, respectively. In half-duplex mode, the internal full-duplex receiver input resistors are still connected to pins 11 and 12.Applications Information256 Transceivers on the Bus The standard RS-485 receiver input impedance is 12kΩ(one-unit load), and the standard driver can drive up to32 unit loads. The MAX3080 family of transceivers havea 1/8-unit-load receiver input impedance (96kΩ), allow-ing up to 256 transceivers to be connected in parallel on one communication line. Any combination of these devices and/or other RS-485 transceivers with a total of 32 unit loads or less can be connected to the line.Reduced EMI and Reflections The MAX3080–MAX3085, and MAX3089 with SRL = V CC or unconnected, are slew-rate limited, minimizing E MI and reducing reflections caused by improperly termi-nated cables. Figure 14 shows the driver output wave-form and its Fourier analysis of a 20kHz signal transmitted by a MAX3086/MAX3087/MAX3088, and MAX3089 with SRL = GND.

Figure 15 shows the same signal displayed for a MAX3083/MAX3084/MAX3085, and MAX3089 with SRL = V CC ),transmitting under the same conditions. Figure 15’s high-frequency harmonic components are much lower in amplitude, compared with Figure 14’s, and the poten-tial for E MI is significantly reduced. Figure 16 shows the same signal displayed for a MAX3080/MAX3081/MAX3082, and MAX3089 with SRL = uncon-nected, transmitting under the same conditions. Figure 16’s high-frequency harmonic components are even lower.In general, a transmitter’s rise time relates directly to the length of an unterminated stub, which can be driven with only minor waveform reflections. The following equation expresses this relationship conservatively:Length = t RISE / (10 x 1.5ns/ft)where t RISE is the transmitter’s rise time.For example, the MAX3080’s rise time is typically 1320ns, which results in excellent waveforms with a stub length up to 90 feet. A system can work well with longer unterminated stubs, even with severe reflections, if the waveform settles out before the UART samples them.100kHz/div 0Hz 1MHz20dB/divM A X 3080/3089 F I G -14Figure 14.

In shutdown, the devices typically draw only 1nA 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.E nable times t ZH and t ZL in the Switching Char-acteristics tables assume the part was not in a low-power shutdown state. E nable times t ZH(SHDN)and t ZL(SHDN)assume the parts were shut down. It takes drivers and receivers longer to become enabled from low-power shutdown mode (t ZH(SHDN), t ZH(SHDN)) than from driver/receiver-disable mode (t ZH , t ZL ).Driver Output ProtectionTwo mechanisms prevent excessive output current and power dissipation caused by faults or by bus con-tention. The first, 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 ). The second, a ther-mal shutdown circuit, forces the driver outputs into a high-impedance state if the die temperature becomes excessive.Line Length vs. Data RateThe RS-485/RS-422 standard covers line lengths up to 4000 feet. For line lengths greater than 4000 feet, use the repeater application shown in Figure 17.Figures 18, 19, and 20 show the system differential volt-age for the parts driving 4000 feet of 26AWG twisted-pair wire at 110kHz into 120Ωloads.Typical ApplicationsThe MAX3082/MAX3085/MAX3088/MAX3089 trans-ceivers are designed for bidirectional data communica-tions on multipoint bus transmission lines. Figures 21and 22 show typical network applications circuits.These parts can also be used as line repeaters, with cable lengths longer than 4000 feet, as shown in Figure 17.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 possible. The slew-rate-limited MAX3082/MAX3085,and the two modes of the MAX3089, are more tolerant of imperfect termination.Slew-Rate-Limited RS-485/RS-422 TransceiversFigure 17.
