Async Test - Toshiba T2000SXe User Manual

Both the output mode and bi-directional mode are tested.

3.10 ASYNC Test

Subtests 01 through 04 requires the following data format:
Method:
Speed:
Data:
Stop bit:
Data pattern: 20h to 7Eh
Subtest 01 Wrap around (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 given in Appendix F.
This subtest checks the data send/receive function through the wraparound connec-
tor.
Subtest 02 Board (#1) <=> board (#2)
NOTE: To execute this subtest, an RS-232-C direct cable (9-pin to 9-pin) must be
connected to channels 1 and 2. The RS-232-C direct cable wiring diagram is given in
Appendix F.
This subtest checks the data send/receive function through the RS-232-C direct
cable.
Subtest 03 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 03) and the other set as
'receive' (subtest 04). The wiring diagram for the RS-232-C direct cable is given in
Appendix F.
This subtest sends 20h through 7Eh data to the receive side, then receives the data
back and compares it to the original data.
Subtest 04 Point to point (receive)
Asynchronous
9600 bps
8 bits and one parity bit (EVEN)
One stop bit
