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
SRM 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 can-
celing the SRN setting of all the sets in the system. First, set
the satellite machines, then set the master machine.
Setting procedure
