Service manual

• Master machine setting
In the menu screen, select "Data Transmission Check (Master
Machine)." The display is as shown below.
Enter the terminal No. (000 ~ 254, 3 digits) of the machine to be
checked and press the ENTER key. The display is as shown
below.
Enter the terminal No. (000 ~ 254, 3 digits) of the machine to be
connected to the machine to be checked and press the ENTER
key. The display is as shown below.
When checking with two or more satellite machines connected,
enter the terminal No. (000 ~ 254, 3 digits) and press the EN-
TER key similarly. To execute, press the ENTER key without
entering the terminal No. The display is as shown below. Do not
use the same terminal No. for different machines (master/satel-
lite).
With the above setting, data transmission between the master
machine and the satellite machine is started.
Check content
• Data in the following format composed of 2byte sequence No.
and 254byte AAH data are transmitted from the master ma-
chine to the satellite machine. The master machine displays the
sequence No.
• The satellite machine sends back the received data to the mas-
ter machine. The satellite machine displays the received se-
quence No.
• The master machine receives the data, and checks the se-
quence No. and 256byte AAH data. In case of an error, the
master machine displays an error code and terminates the
check. If two or more satellite machines are used, the above
operation is repeated. If data transmission with all the satellite
machines are normally completed, the master machine incre
ments the sequence No.
The above operation is repeated.
Error display
The error codes are as shown below.
01 Command abnormality (except for during transmission)
02 No data received.
03
Received data present.
Received data remained.
04
Remote station not ready (in sending)
"NTDY" is sent back because the remote station is not
ready for reception.
05
Reception buffer full (in sending)
The controller reception buffer of the remote machine is full.
06
Resend error (in sending)
Retry over (5 times) when no response
07
Collision error (in sending)
When an collision occurred in data transmission
08
Line busy time out
Transmission cannot be made by multi-station
communication to cause time out in data send wait time.
09
Reception size over (in receiving)
The reception buffer size is insufficient.
0A
Hardware error
Interface abnormality (No SRN interface or abnormality in
SRN controller)
Terminating procedure
Press the CANCEL key to terminate the check. After terminating,
