Subtest 03
Wrap around (Execution time: 1 second)
Note: A printer wraparound connector is necessary for
executing this test. Wiring diagram of the printer wrap
around connector described in the part 3.22.
Checks the data, control, and status lines with the
printer wrap around connector.

3.10 ASYNC TEST
For subtest 01 to subtest 05, transmission is done as follows in the
communication.
Speed:
9600 BPS
Data:
8 bits + parity (EVEN)
1 stop bit
20H to 7EH
Subtest 01
Wrap around (channel 1) (Execution time: 1 second)
Note:
An RS232C wrap around connector must be connected to
channel 1 to execute this test. RS232C wrap around
connector wiring diagram described in part 3.22.
Performs a data send/receive test with the wrap around
connector for the channel 1.
Subtest 02
Wrap around (channel 2) (Execution time: 1 second)
Performs the same test as
Subtest 03
Point to point (send) (Execution time: 1 second)
Note:
This test can be executed on condition that the both send
and receive sides are set in the same condition, and also
connected together by RS232C direct cable (Wiring diagram
described in part 3.22.).
together with
In this test, the data (20H to 7EH) are sent as one block
from one side to the other, and then returned from the
later
one to the first side again. This test is used to check
whether the returned data are same as the original ones.
Subtest 04
Point to point (receive) (Execution time: 1 second)
This test is exactly the same as
the data flow is completely opposite.
subtest 01 for the channel 2.
Subtest 03 must be executed
subtest 04 and vice versa.
