TL F 66099334 DM9334 8-Bit Addressable LatchJune19899334 DM93348-Bit Addressable LatchGeneral DescriptionThe DM9334is a high speed8-bit Addressable Latch de-signed for general purpose storage applications in digitalsystems It is a multifunctional device capable of storing sin-gle line data in eight addressable latches and being a one-of-eight decoder and demultiplexer with active level highoutputs The device also incorporates an active level lowcommon clear for resetting all latches as well as an activelevel low enableThe DM9334has four modes of operation which are shownin the mode selection table In the addressable latch modedata on the data line(D)is written into the addressed latchThe addressed latch will follow the data input with all non-addressed latches remaining in their previous states In thememory mode all latches remain in their previous state andare unaffected by the data or address inputsIn the one-of-eight decoding or demultiplexing mode theaddressed output will follow the state of the D input with allother inputs in the low state In the clear mode all outputsare low and unaffected by the address and data inputsWhen operating the device as an addressable latch chang-ing more than one bit of the address could impose a tran-sient wrong address Therefore this should only be donewhile in the memory modeThe function tables summarize the operation of the

This monolithic stepper IC consists of [deleted two per D. Mortensen] a dual output H-Bridge coil driver [deleted plural s for accurate tense] and theassociated control logic. The dual H-Bridge driver is used to automatically control the speed, direction, and magnitude of current through the coils of a two-phase instrumentation stepper motor, similar to an MMT-licensed AFIC 6405 of Switec MS-X 156.xxx motor.FUNCTIONAL PIN DESCRIPTIONCOSINE POSITIVE (COS0+)The H-Bridge pins linearly drive the sine and cosine coils of a stepper motor, providing four-quadrant operation.COSINE NEGATIVE (COS0-)The H-Bridge pins linearly drive the sine and cosine coils of a stepper motor, providing four-quadrant operation.SINE POSITIVE (SIN+)The H-Bridge pins linearly drive the sine and cosine coils of a stepper motor, providing four-quadrant operation.SINE NEGATIVE (SIN-)The H-Bridge pins linearly drive the sine and cosine coils of a stepper motor, providing four-quadrant operation.GROUND (GND)Ground pins.CHIP SELECT (CS)The pin enables communication with the master device. When this pin is in a logic [0] state, the 33977 is capable of transferring information to, and receiving information from, the master. The 33977 latches data in from the Input Shift registers to the addressed registers on the rising edge of CS.The output driver on the SO pin is enabled when CS is logic [0]. When CS is logic high, signals at the SCLK and SI pins are ignored and the SO pin is tri-stated (highimpedance). CS will only be transitioned from a logic [1] state to a logic [0] state when SCLK is logic [0]. CS has an internal pull-up (I UP ) connected to the pin, as specified in the section of the Static Electrical Characteristics Table.SERIAL CLOCK (SCLK)SCLK clocks the Internal Shift registers of the 33977device. The SI pin accepts data into the Input Shift register on the falling edge of the SCLK signal, while the Serial Output pin (SO) shifts data information out of the SO Line Driver on the rising edge of the SCLK signal. It is important that the SCLK pin be in a logic [0] state whenever the CS makes any transition.SCLK has an internal pull down (l DWN ), as specified in the section of the Static Electrical Characteristics Table. When CS is logic [1], signals at the SCLK and SI pins are ignored and SO is tri-stated (high impedance). Refer to the data transfer Timing Diagrams on page 9.SERIAL OUTPUT (SO)The SO data pin is a tri-stateable output from the Shift register. The Status register bits are the first 16 bits shifted out. Those bits are followed by the message bits clocked in FIFO, when the device is in a daisy chain connection or being sent words that are multiples of 16 bits. Data is shifted on the rising edge of the SCLK signal. The SO pin will remain in a high impedance state until the CS pin is put into a logic low state.SERIAL INPUT (SI)The SI pin is the input of the SPI. Serial input information is read on the falling edge of SCLK. A 16-bit stream of serial data is required on the SI pin, beginning with the mostsignificant bit (MSB). Messages that are not multiples of 16 bits (e.g., daisy chained device messages) are ignored. After transmitting a 16-bit word, the CS pin must be de-asserted (logic [1]) before transmitting a new word. SI information is ignored when CS is in a logic high state.RETURN TO ZERO (RTZ)This is a multiplexed output pin for the non-driven coil, during a Return to Zero (RTZ) event.VOLTAGE (VDD)The SPI and logic power supply input will work with 5.0 V supplies.RESET (RST)If the master decides to reset the device, or place it into a sleep state, the RST pin is driven to a Logic [0]. A Logic [0] on the RST pin forces all internal logic to the known default state. This input has an internal active pull-up.VOLTAGE POWER (VPWR)This is the power supply pin.FUNCTIONAL DESCRIPTIONFUNCTIONAL INTERNAL BLOCK DESCRIPTION (OPTIONAL) FUNCTIONAL INTERNAL BLOCK DESCRIPTION (OPTIONAL)Figure 6.

The two-phase stepper motor has maximum allowable velocities andacceleration and deceleration. The purpose of the steppermotor state machine is to drive the motor with the maximumperformance while remaining within the motor’s voltage,velocity, and acceleration constraints.A requirement of the state machine is to ensure thedeceleration phase begins at the correct time and pointerposition. When commanded, the motor [will deleted PV]accelerates constantly to the maximum velocity, and then itmoves toward the commanded position at the maximumvelocity. Eventually, the pointer reaches the calculatedlocation where the movement has to decelerate, safelyslowing to a stop at the desired position. During thedeceleration phase, the motor does [will deleted PV] notexceed the maximum deceleration.During normal operation, both stepper motor rotors aremicrostepped at 24 steps per electrical revolution, illustratedin Figure 7. A complete electrical revolution results in twodegrees of pointer movement. There is a second smaller[parentheses removed-unnecessary] state machine in the ICcontrolling these microsteps. The smaller state machinereceives clockwise or counter-clockwise index commands attimed intervals, thereby stepping the motor in the appropriatedirection by adjusting the current in each coil. Normalizedvalues are provided in Table 5.Figure 7. Clockwise MicrostepsTable 5.

The time between steps defines the motor velocity and the changing time defines the motor acceleration.The state machine uses a table to define the allowed time and the maximum velocity. A useful side effect of the table is that it also allows the direct determination of the position at which the velocity should reduce to stop the motor at the desired position.Motor motion equations follow: [reworded for efficient use of space](The units of position are steps and velocity and acceleration are in steps/second and steps/second2.) From an initial position of 0 with an initial velocity (u), the motor position (s) at a time (t) is:For unit steps, the time between steps is:This defines the time increment between steps when the motor is initially traveling at a velocity u. In the ROM, this time is quantized to multiples of the system clock by rounding upwards, ensuring acceleration never exceeds the allowed value. The actual velocity and acceleration is calculated from the time step actually used. Using:andand solving for v in terms of u, s, and t gives:The correct value of t to use in the equation is thequantized value obtained above.From these equations, a set of recursive equations can be generated to give the allowed time step between motor indexes when the motor is accelerating from a stop to its maximum velocity.Starting from a position p of 0 and a velocity v of 0, these equations define the time interval between steps at each position. To drive the motor at maximum performance, index commands are given to the motor at these intervals. A table is generated giving the time step *t at an index position n. Note: [chgd for format consistency AND deleted that as PV] For p n = n, on the nth step, the motor [has deleted as PV] indexed by n positions and has been accelerating steadily at the maximum allowed rate. This is critical because it also indicates the minimum distance the motor must travel while decelerating to a stop. For example, the stopping distance isalso equal to the current value of n.The algorithm of pointer movement can be summarized in two steps:1.The pointer is at the previously commanded positionand is not moving.2. A command to move to a pointer position (other thanthe current position) has been received. Timed indexpulses are sent to the motor driver at an ever-increasing rate, according to the time steps in Table 6, until:aThe maximum velocity (default or selected) isreached after which the step time intervals will nolonger decrease.bThe distance in steps that remain to travel are less than the current step time index value. The motorthen decelerates by increasing the step timesaccording to Table 6 until the commandedposition is reached. The state machine controlsthe deceleration so that the pointer reaches thecommanded position efficiently.An example of the velocity table for a particular motor is provided in Table 6.

Launch KPG-25D.exe and start with an empty template by selecting New from the File menu.II. Set the Model to TK-941.III. Select Feature Option from the Edit menu.IV. Set the T.O.T. (Dispatch) parameter to 600. This is the transmission time limit, in dispatch mode, expressed in 15 seconds per step with a range of from 15 seconds to 600 seconds. The default is 60 seconds. These are set to 10 minutes (600 seconds) so that the timers in the repeater controller can be used.V. Set the T.O.T. (Tel)parameter to 600. This is the transmission time limit, in telephone mode, expressed in 15 seconds per step with a range of from 15 seconds to 600 seconds. The default is 180 seconds. These are set to 10 minutes (600 seconds) so that the timers in the repeater controller can be used.VI. Set the Drop out delay time parameter to 1. This sets the time between carrier detect drop out and the resumption of scanning. This parameter can be set from 0 to 254 seconds at 1 second per count. The default is 3 seconds.VII. Set the dwell time parameter to 1. This sets the time between the end of transmission and the resumption of scanning. This parameter can be set from 0 to 254 seconds at 1 second per count. The default is 15 seconds.VIII. Set the Transpond delay time parameter to 3. This sets the delay from the decode of a transpond enabled ID to the beginning of a transpond transmission. This parameter can be set from 0 to 254 seconds at 1 second per count. The default is 3 seconds. If this parameter is set to a value greater than the Drop out delay time then the Drop out delay time will be used as the Transpond delay time.IX. Set the TX inhibit time parameter to 5.0. This parameter sets the period of time that the transmitter is inhibited after an inhibited ID is detected. The value can be set from 0.5 seconds to 8.0 seconds in 0.5 second steps.X.

Del/Add: Provides the user system Delete / Add button.XI. Set the Scan switch parameter to List scan. This parameter sets the scan type selection as follows:A. N/A:Disables the scan switch function and sounds an alert tone (if programmed) when the scan key ispressed.B. List Scan: Automatic roaming scan.C. Fix System Scan: Operator selectable system scan.XII. Set the Revert sys type parameter to Last Use. This parameter sets the programmable transmit destination system & group during scanning. Options include:A. Last Used: Last transmitted system & group.B. Last Called: Last received system & group.XIII. Set the Free System ring back parameter to No. This feature is only active during telephone use (trunked system). The radio will beep when the telephone interconnect line is not busy.XIV. Set the Clear to talk beep parameter to Yes. Upon successful access of a trunked system, this beep tone sounds to alert the user they can begin speaking.XV. Set the System search parameter to None. While a selected system is busy (the radio sounds an intercept tone) then release the PTT key, the radio will start to search for an available system automatically or manually. Options include:A. None: Disable system search.B. Auto: During the intercept tone, keep the PTT key held down and press the SCAN key. Upon release of theSCAN key, system search begins.C. Manual: During the intercept tone, releasing the PTT will initiate auto system search.XVI. Set the Display Character parameter to Grp Name. This parameter selects the display character Group name (Alphanumeric) or System & Group number. If you select the AUX switch as the display character, this selection will be just as default. Options include:A. Sys Grp: Set the display character as System & Group number.B. Grp Name: Set the display character as alphanumeric (pre-programing necessary).XVII. Set the Minimum volume parameter to 0. The minimum volume is the level which will be set automatically every time you turn on the radio. If the volume is adjusted below this level prior to turning the radio off, the volume will be set to this level the next time the radio is turned on. In order to ensure that the speaker is quiet at the repeater site, this value is set to zero. The default value is 8.XVIII. Set the Off hook scan parameter to Disable. The radio is able to scan, even with the mic off hook. Options include:A. Enable: Scan start & stop is independent of the mic hook switch.B. Disable: Mic must be on hook for scanning to start.XIX. Set the Off hook horn alt parameter to Disable. Horn alert is auto disabled when the microphone goes off hook Options include:A. Enable: Off hook auto disable.B. Disable: Manual disable only.XX. Set the Off hook decode parameter to Enable. The radio is still tone squelched, even though the mic is in the off hook condition (valid for QT, DQT and Option Signaling board decode). Options include:A. Enable: Decode signaling active even in the off hook condition.B. Disable: Decode signaling is disabled during off hook.Setting this parameter to Enable allows the radio to operate in decode without having to wire the off-hook signal to the on-hook position.XXI. Set the Access logic sig parameter to Sngl. Pulse. This logic signal is useful for external radio control unit (i.e. Mobile Data Terminal, Computer Aided Dispatch or Over The Air Re-Programming etc) that require a signal at the time of successful trunked repeater access. Options include:A. Continuous: Logic Level high during length of access.B. Sng. Pulse: Logic level high pulse at the time of a successful handshake.XXII. Set the Horn alt logic sig parameter to Pulse. The Horn Alert logic can be used to drive a vehicle horn relay, light or other device. The logic level signal can be set for a continuous (EX: light) or momentary pulse output (EX: vehicle horn relay). Options include:A. Continuous: Continuous logic level low output until reset.B. Pulse: Momentary logic level low output.XXIII.The options should now appear as:XXIV. Layout all of the repeater input frequencies in the first group. Setup each repeater output frequency in a separate system.

Set the transmit Encode field as appropriate.C. Set the receive Decode field as appropriate.D. Set the Grp-Name field as appropriate. Use unique text that will help you identify the group name whenusing the HxD program at a later step.E. Set the TlkArnd field to Yes.F. Leave all other fields at their default values.XXVIII. Save the KPG25D configuration file.XXIX. Exit the KPG25D.exe program.XXX. The KPG25D.exe program will have inserted a value of 0x089B, corresponding to channel 200 or 937.5000 MHz, into each of the frequency slots. The channel numbers are stored as a 16-bit word in little endian format. Endian swapping the default channel value results in a value of 0x9B08, which converts to a decimal value of 39688. The decimal channel value can be determined by subtracting the target frequency from 937.5000 MHz and then dividing by the channel frequency step size of 0.0125 MHz. The resulting value is then subtracted from a value of 38923, converted back to hexadecimal and then endian swapped into little endian format before storing the frequency. This is apparently what the Kenwood3.exe program does (except that the conversion to decimal and endian swapping is not required in programming since little endian is the native format for x86 processors).XXXI.

Program the radio.Filter InstallationTwo TK-941 radios are used to implement the full-duplex link back-bone, with one radio acting as the transmitter and the other radio acting as the receiver. The front-end filter on the receive radio must be swapped out with a filter that has the bandpass frequency having the receive frequency fall within the bandpass.A hot air SMD station was used to remove the pair of filters from the TK-941 receive radio front-end. 915 MHz filters were then installed using a standard soldering station. Note that the filter terminals did not align with the solder pads on the printed circuit board. The terminals had to be bent in to contact the pads prior to soldering. A check was made, using an Ohm meter, to verify that the terminals did not short to the ground traces surrounding the filter terminal pads.Upon completion of the filter installation, the VCO was adjusted to obtain VCO lock.Repeater Controller Interface - Receive RadioThe repeater controller interface requires access to the COS signal and de-emphasized audio. The signal driving the BASE of Q20 presents an Active LOW COS. Further, the COS signal carries only the COS when programmed for COS access or the logical NAND of COS and Tone Decode when programmed for tone or DCS access. The observed logic level on the COS signal shows 3.6 volts when HIGH.Squelch gated de-emphasized audio is available at the junction of C75 and IC6-13. The signal level of the audio, using a 1KHz tone with 3KHz deviation (as used for a -12 dB SINAD measurement), was observed to be 1.2 Vpp.The following annotated PCB view shows where to connect the COS and Gated Audio signals to interface to the repeater controller.The following image shows the repeater controller interface wires attached to the receive radio. The COS wire is blue. The squelch gated de-emphasized audio is orange. A black ground connection is made at emitter of Q20. A Dremel tool was used to grind a small slot to route the cable out of the RF shielded area where the interface signals are available. A Hot Glue gun was used to fasten down the wires, providing strain relief for the PCB pad connections.The power cable chassis strain relief can be lifted, exposing a small but removable plug. Removing this plug allows for routing of the repeater controller interface wires out of the radio chassis.Repeater Controller Interface - Transmit RadioThe transmit radio requires access to the PTT and Microphone input signals. The front panel was removed in preparation to route wires from under the power cable and on to through the chassis to the front panel PCB.The attachment points on the back of the front panel PCB are well marked as follows:1. PTT: Push-to-talk (Green Wire)2. ME: Microphone Return (audio-signal-ground - Black Wire)3. MI: Microphone Input (Red Wire)。
