Wiring Connections
CVM1/CV-series host link units have two types of connector, which must be wired differently.
The NT600S does not use pin 4 (RS) or pin 5 (CS). Either short the RS and CS pins of the PC connector together
or set the CTS setting selector switch at the rear face of the host link unit to “0V” (see

in the figure).
Connect the cable shielding wire to the connector cover and pin 1 at the host link unit end of the cable only.
