4) Data Transmission Check

Data transmission is checked in an actually composed system. The
system is composed of one master machine and max. 15 satellite
machines.
Note for starting the check
•
When checking the set in which the SRN setting has been made,
cancel the SRN setting before starting this check.
•
When checking the actually composed system, disconnect the
SRN cables of the sets which are not checked, or cancel the SRN
setting. If it is set to "SRN exits," data may be destroyed.
•
The transmission check setting must be performed after canceling
the SRN setting of all the sets in the system. First, set the satellite
machines, then set the master machine.
