4) Data Transmission Check
Data transmission test is executed in an actually constructed system.
The system is composed of one master machine and max. 15 satel-
lite machines.
Precautions when starting the test
When testing a set where SRN setting has been made, release the
SRN setting before starting this test.
When testing in an already constructed system, disconnect the
SRN cable of the set which are not subject to the test or release
the SRN setting. If not, data may be destroyed.
Setting of the transmission test must be made after releasing the
SRN setting of all the sets in the system. Be sure to set the
satellite machines then the master machine.
Setting procedure
i. Satellite machine setting
Select "Data Transmission Check (Satellite Machine)" in the
menu. The Terminal number is read from the DIP SW1, (ER-
01 IN) and the following procedures are performed. The fol-
lowing display will be shown.
