3 SERVICE T2130
3.5.3.3 RF ON/OFF
Test set-up: Mode 1
A: Connect a voltmeter to the collector of Q11 or at P06 pin 8.
B: Key the transmitter. Voltage is < 0.8 Volt.
3.5.3.4 TELEX OPEN
Test set-up: Mode 1
A: Connect pin 6 ST03 on the Connection Board (6) to ST02 pin 16 SP-BUS INTERRUPT, and connect
pin 5 ST03 to ST02 pin 4 +18V.
B: Connect a voltmeter to the collector of Q10.
C: Select „TLX“ mode on the RE2100 and key the transmitter.
Check that Q10 is on (low).
D: Select „J3E“ mode on the RE2100.
Check that Q10 is off (high).
3.5.3.3 AE-CURRENT/VFORWARD CONDITIONING
AE-CURRENT
Test set-up: Mode 1. Turn „RF“ fully clockwise.
A: Connect a voltmeter to ST02 pin 2 on the Connection Board (6).
B Disconnect the wire at pin 3 at ST01 on the Connection Board (6) and connect a variable power supply
to pin 3 at ST01 with a 1 Kohm in series (negative terminal to chassis).
C: Vary the power supply and check the voltmeter according to the table below:
Vin (ST01, pin 3): Vout (ST02, pin 2):
0.0V 0.87V ±10%
5.0V 4.27V ±10%
10.0V 7.77V ±10%
15.0V 8.00V ±10%
18.5V 9.80V ±10%
VFORWARD
Test set-up: Mode 1.
A: Insert jumper 5 in the TX-processor.
B: Switch off/on the RE2100.
C: Connect a voltmeter to U06 pin 7 or at ST02 pin 2 on the Connection Board (6).
D: Key the transmitter and modulate. Read the voltmeter. Voltage follows the modulation.
E: Remove the jumper.
3.5.3.6 AT2110 DRIVER
CLOCK DRIVER
Test set-up: Mode 2.
A: Connect an oscilloscope (0.5 msec/div, 5 Volt/div) to ST01, pin 5 on the Connection
Board (6), ground to ST01, pin 10.
Voltage is low, < approx. 1 Volt.
B: Set the RE2100 to scan two frequencies, one below 3900 kHz, and the other above
4100 kHz.
24 clock pulses appear. The high level is approx. +21 Volt.
