ASYNC TEST
In subtest 01 to subtest
OS,
data transmission is done with the
following format:
Subtest 01
Subtest 02
Subtest 03
Speed:
9600 BPS
Data
8 bits and one parity bit (EVEN)
One stop bit
Data pattern:
20H to 7EH
Wrap around (board)
NOTE:
The RS-232-C wraparound connector must be
connected to channell to execute this test.
The
wiring diagram of the RS-232-C wraparound
connector is described in part 3.25.
A data send/receive test is performed with the
wraparound connector for the channell.
Board (#1)
<=>
board (#2)
NOTE:
The RS-232-C direct cable (9-pin to 9-pin)
must be connected to channel 1 and 2 to execute
this test.
The wiring diagram of the RS-232-C
direct cable is described in part 3.25.
The same test as the subtest 01 is performed for
the channel #1
<=>
#2
Point to point (send)
NOTE:
This subtest must be executed in condition
that two machines are connected with the RS-232-C
direct cable and one side should be set as 'send'
and the other set as 'receive'. The wiring diagram
of the RS-232-C direct cable is described in part
3.25. The subtest 03 executed in one side and the
subtest 04 executed in the other will check the
communication capability as follows:
A block of data (20H to 7EH) is sent from one side
to the other, and then returned back.
The
returned data is compared with the original one.
This test is used to check whether the returned
data are same as the original ones.
