Appendix A - DIP Switch Settings
The 10-position DIP Switch is used to configure:
• RS-485 Communication protocol (pos 1)
• Ethernet Communication protocol (pos 2)
• RS-485 Baud rate (pos 3 & 4)
• Single channel input mode for RJ45 style connector and ST (screw terminal); dual-channel only available on
RJ45. (pos 5)
• Spare Pos 7 & 8
• RS-485 Bias (pos 9 & 10); only one device on the network needs to have biasing.
The communication baud rate is selected by means of a DIP Switch on the circuit board. There are four (4)
selections: 9600 (factory default), 19.2k, 38.4k, and 76.8k bps; higher baud rate would reduce cabling length.
When connecting the device to an RS-485 network needing the use of biasing the RS-485 line, turn on DIP
Switch pos 9 and pos 10. After changing the DIP switch selections (1.8), restart the device for the new settings to
take effect (9&10 for BIAS doesn’t require CPU restart).
