When using a RS-422 cable (C200H-LK202-V1 Host Link Units) throughout a
system, the Host Link Unit at each end of the cable system (as detailed in the
following diagram) must have the termination resistances connected by turning
ON the switch on the back of the panel. When this switch is set to ON, a built-in
termination resistance of 220 Ω is connected. When set to OFF, the termination
resistance is disconnected.
For RS-232C models (C200H-LK201-V1), the selector is set to 0 V, the
clear-to-send (CTS) signal is continuously ON. When the selector is set to exter-
nal, the Unit will respond to externally generated 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 with an RS-232C Host Link Unit, the
5 V power supply switch should be set to ON; otherwise it should be set to OFF.
On the C200H-LK201-V1, pin 4 on the back-panel DIP switch functions as the
5 V power supply switch.
Pin 3 on the back-panel DIP switch of the C200H-LK201-V1 (RS-232C connec-
tion), and the Link Type Selector on the rear of the C200H-LK101-PV1 (optical
fiber connection) provide the same functions as described below.
OFF (Single-link):
If set to OFF, the Host Link Unit is connected to the host computer on a
one-to-one basis (see Example 3 and Example 5 under 1-2 System Configura-
tion. The Unit number and Frame Checksum (FCS) settings are not required.
The normal setting is ON (see below).
Turn the termination resistance ON for these two Host Link Units.
