T2150 Series
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
T2150 series 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: Asynchronous
Speed: 9600BPS
Data: 8 bits and one parity bit (EVEN)
Data pattern: 20h to 7Eh
The following message will appear 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 (1/2/3)
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 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
diagram is described in Appendix G.
This subtest checks the data send/receive function through the RS-232-C
direct cable.
