3.10 Async Test

To execute the Async Test, select 7 from the DIAGNOSTIC TEST menu, press Enter and
follow the directions displayed on the screen. The Async Test contains six subtests that test the
T1900/T1900C's asynchronous communication functions. Move the highlight bar to the subtest
you want to execute and press Enter.
Subtests 01 through 04 require the following data format:
Method:
Speed:
Data:
Data pattern:
The following message appears at the bottom of the screen when Subtests 01, 03, 04, and 05
are selected:
Channel#1 = XXXXh
Channel#2 = XXXXh
Channel#3 = XXXXh
Select the Channel number (1 - 3)
The serial I/O port address is specified by the XXXXh number. Select the serial port channel
number, and press Enter to start the subtest.
Subtest 01 Wraparound (board)
NOTE: To execute this subtest, an RS-232-C wraparound connector
(34M741621G01) must be connected to the RS-232-C port. The RS-232-C
wraparound connector wiring diagram is described in Appendix G.
This subtest checks the data send/receive function through the wraparound
connector.
Subtest 02 Board (#1) <=> board (#2)
NOTE: To execute this subtest, an RS-232-C cable (9-pin to 9-pin) must
be connected to Boards 1 and 2. The RS-232-C direct cable wiring dia-
gram is described in Appendix G.
This subtest checks the data send/receive function through the RS-232-C direct
cable.
