Serial Communications Section 6-1
Note When the Serial Gateway function is used, the FQM1 receives FINS com-
mands (encapsulated W-series or SMARTSTEP commands) via the RS-422A
port from NT-series PTs or personal computers and converts them to W-
series or SMARTSTEP Servo Driver commands (removes the encapsulation)
and transfers them to the W-series or SMARTSTEP Servo Drivers.
System Setup
Note The settings are made using CX-Programmer Ver. 5.0@ menus.
