Checking content
A loop check is performed for ER-A8RS I/O address 278H
∼
27FH
(PARALLEL2), In the loop check, the loop cable shown in Fig, 3-4
is connected between PARALLEL2 (ER-A8RS) and PARALLEL1
for testing. Set the jumpers on the PWB prior to the test as shown
in Fig. 3-6.

4) PARALLEL1 Print Check
1
Checking content
The print check is performed for the standard port PARALLEL1 at
I/O address 378H
∼
37FH. In the print check, the D-Sub 25 pin
connector is connected with a printer to allow a print pattern test.
The test procedures are as follows:
i. Data of 55H is written to I/O address 378H, and the same
address is read. If the read data is not 55H, "PARALLEL1
Channel Disabled" is displayed and the following check is not
performed.
ii. Characters of 20H
∼
7FH (ASCII code) are printed and the
line is changed.
This procedure is repeated for 5 times.
