Running Diagnostics from a Serial Terminal
Disconnect the concentrator from the host adapter and other
concentrators before running diagnostic tests.
To run the internal diagnostic programs from a serial terminal, turn off the
concentrator and connect the terminal to either port 1 or port 16 (use a cable
similar to the one shown in Figure 21, on page 30). Set the terminal's commu-
nications parameters to VT-100 emulation, 9600 baud, 8 data bits, no parity and
1 stop bit. Now turn the concentrator back on, and wait for the POST (Power
On Self Test) 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:

Operator Commands:
<Y>/<N> - Stop on 1st error = Y
<B>ell - Bell rings for each error = ON
<D>ump - Dumps 256 bytes of the selected memory.
<ESC>ape - Stops the test in progress.
<S>et - Sets the node number in EEPROM.
<T>oggle - External/Internal mode for EIA-422 & EIA-232 tests = INTERNAL
