5.2 ROCKWELL MODEM TEST
The GETC shelf setup procedures to configure it as the test fixture for the Rockwell Modem follows. These
procedures need to be implemented only once on the specified GETC shelf to be used as the Rockwell
Modem test fixture.
1) Plug the Rockwell Modem into J3 on the GETC test fixture.
2) Install P11 between J11-1 and J11-2 on the GETC logic board.
3) Connect a jumper between J6-7 and J6-9 on the GETC.
4) Connect a jumper between J6-6 and J6-8 on the GETC.
5) Install a 680 ohm resistor (1/4 watt) between J6-8 and J6-9.
6) Adjust R1 to about half range on the GETC.
7) Adjust R2 to about half range on the GETC.
The procedures to test the Rockwell Modem follows:
l) Plug the Rockwell Modem into the test fixture.
2) Apply power (13.8 volts) to the GETC shelf and the SIMON welcome message is displayed on the
terminal. The GETC is DTP switch configured for SIMON operation prior to power up. See
19A701179 for dip switch set-up.
3) Type "TIM 19" on the terminal to set the time delay from RTS to beginning of data to 250
milliseconds.
4) Execute the SIMON command "MDS 1" to select the phone modem for subsequent BER
command.
5) Execute the SIMON command "BER DE-00=10". This command transmits data and
simultaneously checks to see that data is being received. The terminal should respond with the
following: Error Count = 0000 Receive Checksum = 00188123
If the terminal does not respond with the above data, the Rockwell Modem has failed the test and
needs to be returned to the vendor.
The test continually runs, outputting data to the terminal in 10 second intervals.
6) After four consecutive test periods (10 seconds per test period) with data outputted to the terminal,
the test can be terminated by pressing a CTRL Z or the ESC key on the terminal.
