I/O Wiring

This section shows the following input/output wiring diagram.
• Power supply wiring to the Main Unit and infrared thermal sensors
• RS-485 wiring between the Main Unit and infrared thermal sensors
• External trigger input wiring, transistor output wiring, and Ethernet communications wiring to the Main
Unit

*1. Fix the cable wiring to the sensors so that the weight of cable does not bear on the connector.
 RS-485 Wiring Length and Recommended Cables
The length of the RS-485 wiring between the Main Unit and infrared thermal sensors is 500 m max.
Use commercially available communications cables with one shielded twisted-pair cable (stranded
wire, 2-conductor) and AWG24 to AWG16 (0.25 to 1.5 mm
• Recommended cable for use between the Main Unit and infrared thermal sensors
Models
2464C BIOS series
 Terminal Sensors in the RS-485 Transmission Path
In the case of terminal sensors in the RS-485 transmission path, turn ON the terminating resistance
(change the sensor DIP switch Pin 6 to ON). Refer to DIP Switch Settings on page 1-17.

Ethernet Wiring

Connect the Main Units with the software tool, PLC, or PC via the industrial switching hub with the
Ethernet cables.
Use an STP (shielded twisted-pair) cable of Ethernet category 5 or higher. You can use either a straight
or cross cable.
