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 eight subtests that test
the asynchronous communication functions. Move the highlight bar to the subtest you want
to execute and press Enter.
Subtests 01 through 08 require the following data format:
Method:
Speed:
Data:
Data pattern:
The following message will appear at the bottom of the screen when subtests 01, 03, 04, 06,
07 and 08 are selected:
Channel#1 = XXXXh
Channel#2 = XXXXh
Channel#3 = XXXXh
Select the Channel number (1/2/3)
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 F.
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 diagram is
described in Appendix F.
This subtest checks the data send/receive function through the RS-232-C
direct cable.
