Error message
The following error message appears if a communication error
occurs with the UP-T80BP.
4
End of testing
The testing is finished after printing is made by the specified num-
ber of times or by pressing the ESC key.
3-9. Serial I/O Diagnostics
The serial interface of UP-5300 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-5300’s 9-pin D-sub ports are used as COM1 and 2. In addi-
tion, the UP-5300’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-5300 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
the Enter key to execute the selected diagnostics program.
When the selected diagnostics program is completed, the display
returns to the menu screen. Pressing the Esc key returns to the
serviceman diagnostics menu.
1) COM1 Check
1
Content
The loop back check is performed for the 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.
2
Display
The number of the interruption request signal is displayed at XX.
If no access is allowed to COM1 UART, the following display is
made.

Terminating method.
Press the Esc key to terminate and return to the Serial I/O diag-
nostics menu.
2) COM2 Check
1
Checking content
The loop back check is performed for the UART at I/O address
2F8H
∼
2FFH. The check procedure, the display, and the ter-
minating method are the same as COM1 Check.
3) COM3 Check
1
Checking content
The loop back check is performed for the UART at I/O address
3E8H. When the ER-A8RS is assigned to COM3, the check pro-
cedure, display and terminating method are the same as COM1.
When the RJ-45 port of the UP-5300 main unit is assigned to
COM3, the following points are different from COM1 Check :
1
Content
•
RTS-CTS is not checked.
•
DTR-RI is not checked.
2
Display
•
RTS-CTS is not displayed.
•
DTR-RI is not displayed.
COM3 is checked as well as COM1 except the above 2 points.
