Turn the termination resistance ON for these two Host Link Units.
When this switch is set to ON, a built-in termination resistance of 220 Ω is con-
nected. When set to OFF, the termination resistance is disconnected. When us-
ing a RS-422 cable throughout a system, the Host Link Unit at each end of the
cable system must have the termination resistances connected by turning ON
the switch as detailed in the following diagram. RS-232C systems provide point-
to-point connections and do not require a termination resistance.
When the selector is set to 0 V, the clear-to-send (CTS) signal is continuously
ON. When the selector is set to external, the Unit will respond to externally gen-
erated CTS signals. This is normally set to CTS always ON, i.e., the switch is set
to ON.
When using a Z3RN-A-5 Optical Interface, the 5 V power supply switch should
be set to ON; otherwise it should be set to OFF.
Sets the Host Link Unit (3G2A5-LK201-EV1 or C500-LK203) to either the
RS-232C or the RS-422 interface.
