XCD Transmitter

Appendix A - Modbus® Protocol A-2

A.1 Modbus and the XCD

The XCD gas detector may be fitted with the optional Modbus board. Authoritative

information on the MODBUS Upgrade Kit can be found at www.modbus.org. The XCD

supports Modbus/RTU over an RS-485 physical layer. The interface is isolated and

includes a switchable 120 Ohm termination resistor. Baud rates 9600 or 19,200 are

supported with 19,200 as the default. Most of the operations that are possible with

local user interfaces can also be performed using the Modbus interface. This includes

configuration operations. However, this Appendix only describes how to monitor XCD

status using Modbus.

See Section 4.1.1 for information on installing the optional Modbus hardware. See Section

4.1.1 Configure Menu – Set ID Settings for information on setting the Modbus baud rate

and Parity using the local user interface.
