6) PARALLEL3 Print Check
Check content
The print check is performed for PARALLEL3 at I/O address
3BCH
~
3BEh on the ER-A8RS.
In the print check, set the short pin of the ER-A8RS to be tested
as shown in Fig. 3-10, and connect D-Sub 25 pin connector to the
printer to allow to print for test.
Fig. 3-10 Jumper pin setting
The test procedures are as follows:
i. Data of 55H is written to I/O address 3BCH, and the same
address is read. If the read data is not 55H, "PARALLEL3
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.
Display
"PARALLEL3 Channel Disabled" is displayed only when no ac-
cess to PARALLEL3 is allowed.
Terminating method.
Press Esc key to terminate.
3-9. Serial I/O Diagnostics
The serial interface of UP-5700 and the option PWB ER-A8RS is
performed. To test the 9pin D-Sub port, connect the D-Sub loop back
connector (UKOG-6705RCZZ).
To test the RJ45 port, connect the loop back connector (UKOG-
6729BHZZ).
Loop back connector (UKOG-6705RCZZ) wiring diagram
Loop back connector (UKOG-6729BHZZ) wiring diagram
The UP-5700’s 9-pin D-sub ports are used as COM1 and 2. In addi-
tion, the UP-5700’s RJ45 ports are used as COM3 and 4 or COM5
and 6 according to the setup. On the other hand, ER-A8RS is used
by selecting either COM1 and 2 or COM3 and 4 according to the
setup.
Therefore, when an ER-A8RS is used, you must set COM1, 2, 5, and
6 on the UP-5700 side, and set COM3 and 4 on the ER-A8RS side.
The following menu is displayed.
The highlighted cursor is moved by the cursor keys (UP
and DOWN
¯
) of the AT keyboard. Move the cursor to the desired item, and press
Enter key to execute the selected diagnostics program.
When the selected diagnostics program is completed, the display
returns to the menu screen. Pressing Esc key returns to the service-
man diagnostics menu.
1) COM1 Check
Content
The loop back check is performed for UART at I/O address 3F8H
~
3FFH. The test procedures are as follows:
i. UART setting is made. If access is denied to UART at that
time, "COM1 Disabled" is displayed and the following check is
not performed.
ii. RTS signal is turned on/off to check that CD, CTS signal is
normally operating. In case of any abnormality, ERROR is
displayed.
iii. DTR signal is turned on/off to check that DSR, RI signal is
normally operating. In case of any error, ERROR is displayed.
When an error occurs in procedure i or ii, the following test is
not performed.
iv. Set the baud rate to 19200bps asynchronous. 256 byte data
of 00H
~
FFH is transmitted from SD signal. Data received at
RD signal is compared to check that the both are the same. If
the outputted data is not returned for 5 sec or more, ERROR
is displayed and the test is terminated.
v. An interruption signal is issued from UART and the number of
generated interruption request signal is displayed.
