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.
2. Refer to 5-4 Troubleshooting for details on correcting the following problems.
ON when the power is on and the Unit is ready to transmit.
ON when the Host Link Unit is receiving data.
ON when the Host Link Unit is transmitting data.
Goes ON when a transfer error is detected (See note 1.); goes OFF when a new
command is received normally.
• The RUN indicator does not light.
• The Host Link Unit’s RCV indicator does not light when data is transmitted
• The RCV indicator lights, but the XMT indicator does not.
• The ERROR indicator lights.
• The XMT indicator lights, but the host computer does not receive the data.
