TESTS
I-E96-221A
5 - 9
0C - RS232 DUART Test
This test exercises both serial channels of the DUART in local
loopback mode. If all parts of the test pass, the DUART is func-
tioning properly.
0E - CTT Module Bus Test
This test sends a series of bytes to the CTT terminal module
bus in loopback mode. The timing and status of the transfer
must be within tolerance.
0F - Null Test
The IMCPM02 module always passes this test.
10 - Group Test
This test runs tests 01 through 0F in sequence, and is
intended to verify proper operation of a IMCPM02 module with
no external slaves or cables required. It is a single IMCPM02
module stand-alone test that can run continuously. For a more
complete checkout of IMCPM02 module functionality, the fol-
lowing individual tests should also be executed: 00 (switches/
LEDs), 11 (DUART external loopback test).
11 - RS232 DUART External Loopback Test
This test exercises both channels of the DUART in external
loopback mode; jumpers J5 and J6 must be positioned in their
loopback settings. If all parts of the test pass, the DUART and
its support circuitry are functioning properly.
