Date Of Issue M087-02-001 27/07/00 Speaker and Channel Switch Issue 001 published July 2000 Copyright TEL M087-02-001 1 Introduction 1 Introduction The TA0087-02-000 Speaker and Channel Switch is a channel change module for T800 Series II Base Stations. It replaces the TA087-01, which was designed to suit the T800 Series I Base Stations. The module requires the T800-08 programmable lead for programming. The TA0087-02-000 module has the following features: ■ Mounts in a standard T800 Series II rack ■ Replaces the standard speaker and programming module ■ Provides up to 256 programmable channel data entries - 99 for BCD coded entries ■ Provides a simple channel change interface with auto-repeating UP/DOWN keys ■ Provides opto coupled connection for remote control buttons ■ Provides a clear 3 digit 7 segment LED display ■ Provides an output connector for changing channels for other modules ■ Provides a remote connector for selecting an index value of channel data blocks ■ Provides an indication LED for REMOTE mode (See Sec 3.4.2) ■ Provides auto revert from local mode ■ Contains a unique serial number ■ Provides an optional RS232C port for serial channel data output ■ Provides a database and programming software ■ Provides easy integration to T800 programming software ■ Provides Binary or BCD mode, selectable during programming ■ Provides programmable input logic: positive or negative Copyright TEL 27/07/00 Specifications 2 2 M087-02-001 Specifications Supply 10.8 - 16V Micro controller 68HC705C8 Dimensions 183 x 59 x 24mm Weight 250gm Environment temperature range: -30 to +60C humidity: 95% Modes local or remote No. of channels Binary : 256 BCD : 99 External up down inputs opto coupled with current limitation Display 3 digit 7 segment display Programming T800 ping-pong protocol Optional RS232 via 9 way D-socket 27/07/00 Copyright TEL Circuit Description M087-02-001 3 3 Circuit Description A 68HC705C8 microprocessor provides the required reading and writing of all I/O lines. 8 Logic outputs are generated from Port A of the micro to select the T800 module channels. The signals are available on D Range SK1. A loom to interface to the T800 rack panel comes as standard with the TA087-02-0000. In remote mode, the processor reads the external inputs via Port B. Inputs can be active high or active low, depending the programming of the TA087-02-0000. A 9 way D-range socket provides easy access. The input ports are protected against positive and negative over voltage. The serial I/O ports of the processor are used to communicate with the EEprom and to write to the output registers for the 7 segment displays. Programming Circuit Programming takes place via the T800-08 programming cable. This cable limits the RS232 voltages to 5V. The processor in the TA087-02-0000 keeps IC10 (4053 analog switch) in Inhibit mode. An incoming data packet - 9600 baud, 1 stop and start bit - will generate an interrupt on pin 2 (IRQ) of the microprocessor. The processor will respond by changing the inhibit line on IC10 to +5V. The same line puts an inhibit on the RS232 output into the micro. Control inputs A and B of IC10 are set high. This prevents R70 and R71 loading R62. Control input C, toggled by the incoming serial data packet, switches output Z between 0 and +5V via Z0 and Z1. The resulting signal constitutes the “ping” or RXD to the microprocessor. When the message is finished the serial comms line goes high impedance. The PC is now waiting for a response. If the data packet contains the correct coding for the unit its processor responds with “pong” by toggling control lines A and B of IC10. The resulting signal at X and Y of IC10 forms the TXD signal. At the end of the exchange the microprocessor reverts the inhibit line on IC 10 to high re-establishing communications between the microprocessor and the RS232 chip. PC RS232C PORT Copyright TEL TXD TXD RXD RXD CPU UART PORT 27/07/00 Circuit Description 4 M087-02-001 Up-down channel control The up down buttons on the front panel are directly connected to two ports on the microprocessor. The opto couplers are connected in parallel with these two buttons and will go low when a current of at least 7mA flows through the input diode. Operation of the opto coupler is typically between +12V and a switch to Gnd.

When the +5V supply drops below 4.75V the output of IC9 switches to Gnd, providing reset to the micro and to the shift registers of the LED displays. 27/07/00 Copyright TEL PCB Information M087-02-001

Mount the module in the rack in the allocated slot and connect it to the rack via the 219-02661-00 cable supplied. The cable plugs into the BACKPLANE PCB at the rear of the rack. 2. Set the 8 pin DIP switches located on the BACKPLANE PCB to OFF 3. Ensure that the receiver and transmitter modules are programmed to the correct frequencies with PGM800Win. 4. To program the Channel Change module use the standard T800 Series II programming cable to connect to a PC. Run PGM S/W: TA2213A914 under Windows. Refer to the Programming section, if more detailed information is required. 5. If the module needs to be set up for external channel selection and monitoring, refer to Operation section. Copyright TEL 27/07/00 Operation 18 7 M087-02-001 Operation The TA087-02-0000 module operates either in Local Mode or in Remote Mode. The mode in which the module powers up is determined by the module programing. If no channel data have been programmed into the module, the display will blink "E" and the keys will not operate. If a channel label exceeds 999, the display will show "- - -". If the channel label is set to “BLANK”, the display will show "_ _ _". Local Mode If Local Mode is set in the programming software, the module will power up in Local Mode. In Local Mode, channel selection takes place via the up and down buttons. When either button is pressed the displays starts blinking with the new channel selected and remains blinking for 3 seconds after release of the button. When the blinking times out, the actual channel information is downloaded to the outputs of the module. Following the highest channel, the display shows "- - -" for 3 seconds and then wraps around to the first channel, and visa versa. When Remote Mode was programmed the module will revert to Local Mode when either Up or Down button is pressed. To change from Local Mode to Remote Mode Manual Select "- - -" with the up down buttons and release the button. After 3 seconds the module will change to REMOTE Mode. Automatic When the Remote Revert Time is set to 0 during programming, the module will not automatically revert to Remote mode. If the Remote Revert Time is set to any other non-zero value, the module will revert to Remote Mode. The time window is between 0 and 255 minutes. This feature avoids the situation whereby the technician forgets to revert the module to Remote, rendering the base station inoperable. 27/07/00 Copyright TEL Operation M087-02-001 19 Remote Mode A red LED on the front panel of the module indicates the Remote Mode To Select Remote Mode Automatically At Power up if the Remote Mode was set during programming From Local Mode when the Remote Revert Time was set to a non zero value during programming Manually From Local mode, select "- - -" with the up and down buttons and release the buttons. After 3 seconds the module will change to Remote Mode. Inputs in Remote Mode The module accepts 8 binary / BCD inputs in the Remote mode with standard or polarity reversed logic levels. The inputs are available on a 9 way D Range Socket PL2. pin 1: Ch Select 0 pin 2: Ch Select 1 ....................... pin 8: Ch Select 7 pin 9: Gnd Logic 1 = high (5V or higher) or open collector.

Check for 13.8V and +5V at in and output of the regulator IC at C20 and C23. 1. Without +13.8V at C20 check cable and T800 rack plane PCB. If no +5V, check VREG for levated temperature. A short on the board will cause the regualtor to heat up. A faulty regulator will be cold. Replace regulator as required. 2. 5V regulator voltage low: Disconnect all cables - except the power cable. Check for components heated up. Use your judgement to either replace the component or check it's output for overloaded conditions. Also check for dry joints on inputs. No channel selection The unit does not respond to neither local nor remote inputs. 1. Check database by reading the unit. If OK skip 2 and 3 2. Check reset input of microprocessor. Make sure input level is +5V. If not check power supply and follow up with procedure for 5V reg. 3. Check oscillator running at 4MHz. Replace Xtal first followed by micro if still not succesfull. 4. Check IRQ input should be +5V. If not work your way back through IC8 and IC 10 to the serial com input. Make sure that the inhibit input at IC10-6 is 0V. 5. Check logic levels for up and down signals on the processor IC1 pin26 & pin 27. If low check opto-couplers. No Display 1. Check the programming of the unit 2. Check for presence of Data, Clock Latch Enable on IC5, 6 and 7, while toggling the up down buttons. 3. No RS232 response RS232 is not yet supported in software Copyright TEL 27/07/00 30 IC Data Sheets M087-02-001 10 IC Data Sheets 27/07/00 Copyright TEL
