3.10 Async Test
To execute the Async Test, select
7
from the DIAGNOSTIC TEST menu, press
Enter
and
follow the directions as they are displayed on the screen. The Async Test contains seven
subtests that test the asynchronous communication functions. Move the highlight bar to the
subtest you want to execute and press
Enter
.
The subtests require the following data format:
Method:
Asynchronous
Speed:
9600 BPS (Subtests 01 to 04)
38400 BPS (Subtests 05 to 07)
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, 02, 03, 05,
06, and 07 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 shown in Appendix F.
This subtest checks the data send/receive function through the wraparound
connector.
Subtest 02
Point to point (Send)
NOTE: To execute this subtest, two machines must be connected with an
RS-232-C direct cable. One machine should be set as "send" (Subtest 02)
and the other set as "receive" (Subtest 03). The wiring diagram for the RS-
232-C direct cable is shown in Appendix F.
This subtest sends 20h through 7Eh data to the receive side, then receives the
sent data and compares it to the original data.
