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

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.

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.
Low voltage protection
A Low Voltage detector has been included in the unit to ensure proper shut down of the
microprocessor to protect the database in the EEprom. 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.

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.

7 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.

Speaker
The speaker in the TA0087-02-0000 is automatically connected to the Back Plane of the
T800 rack. For reasons of convenience the speaker signals are also available on the

Supply problems
The unit derives its power from the T800 rack plane PCB.
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
