With the above procedure, setting and starting of the satellite
machine to be tested are finished, and the master machine is
ready for starting.
Data transmission with the master is performed and the sequence
number of received data is displayed on the display.
When using two or more satellite machines for testing, perform
the above procedure for every satellite machine to be tested. In
this case, avoid repetition of the terminal number.
2 Master machine setting (JOB #604)
The master machine setting should be performed after the com-
pletion of the satellite machine setting. If the master machine is
started before starting the satellite machine, an transmission error
may occur.

With the above procedure, data transmission is started with the
satellite machine in standby state.
When data transmission is started, the sequence No, of transmit-
ted data is displayed on the 7SEG DISPLAY of the master and the
satellite machines.

3 Test content
a. A sequence No. of 2 byte and the format below composed of
0AAH data of 254 byte are transmitted from the master to the
satellite.
The sequence No. is displayed on the 7SEG DISPLAY of the
master.
b. The satellite returns the received data back to the master.
The sequence No. of the received data is displayed on the
7SEG DISPLAY of the satellite.

c. The master receives the data and then checks the sequence
No. and 0AAH data.
If there are two or more satellite machines, steps a and b are
repeated. If all data sent from the satellite are normal, the
master increments the sequence No.
The above steps a through c are repeated.

4 Error display
When an error occurs during the data transmission test, the fol-
lowing display is given and the error print is made.
To cancel the error, perform the program resetting (power
OFF/ON in the SRV mode).

03: Reception size YES
Received data remained
04: The remote station not ready (in transmitting)
The remote station is not ready for reception and re-
turns back "NRDY."
05: Receiving side buffer full
The controller receiving buffer in the remote station is
full.
06: Resend error (in transmitting)
Retry over (5 times) without reply
07: Collision error (in transmitting)
When data transmitting collision occurs, retry over (16
times) after random time (0 - 255 ms).
08: Line busy time out
Transmission is not made because of transmission
between the other remote stations, and data transmit-
ting wait time is out.
09: Reception size over (in receiving)
The reception buffer size is insufficient.
0A: Hhard error
Abnormal interface (no SRN interface or abnormal
SRN controller)
