Diagnostics

59

1.  To run the internal diagnostic programs from the terminal port, turn off the T1 Modem Bank and connect a

terminal to the terminal port. Some terminals will not transmit data if their CTS (Clear To Send) line is LOW.
These terminals must have their CTS line HIGH or floating to ensure that they will have no problems
communicating with the T1 Modem Bank. Appendix C on page 91 shows a cable that can be used for these
terminals.

2.  Power up the terminal and set its communications parameters to 9600 baud, 8 data bits, no parity and 1 stop bit.

3.  Turn the T1 Modem Bank back on and wait for the POST to complete. While 

P1

 is displayed on the front panel,

press the letter 

V

 (either upper or lower case) on your terminal.

You will see the following screen:
