NOTES:
1. An externalloopback connector, Figure 4-10, (DIGITAL part number
12-15336)
must be at-
tached to the terminal to run tests 4, 5, and 6. These tests detect failures in the EIA line driv-
ers and receivers which are not checked on power-up or during self-test. The transmit and
receive baud rates for the terminal must also be identical.
2. The printer confidence tests (7 and 8) send
a
line of text that you type to the printer. The
printer must be set up for these parameters.
Baud rate: 1200·
Bits / character:8
Parity:None
Stop bits: 1
3. The synchronous communications test (9) requires that the terminal's transmit and receive
speeds be identical and be at 2,400 baud or less. The communications port is tested in loop-
back mode; however, no loopback connector is required for this test. Enter SET-UP Band
change the baud rate if you desire to run this test.
• A later revision ROM allows the baud rate to be either 300 or 1,200. This is established using the SET-UP P command.
Refer to the VT180 User's Guide to use this command.
