3.5.1 Modbus Port Settings
The XMT 1000 meter supports digital communications using the MODBUS/RTU protocol, with 3-wire RS-485
as the physical layer interfaces. Baud rate can be specified from 2400 to 115,200 bits per second (bps), with
selectable parity, and number of stop bits (Default = 115200, Even, 1 Stop Bit). Use steps as in section “Log-in
and Primary Pages” to navigate to the Input/Output settings page. Then highlight [Communication Port] and
press [ENTER]. Figure 56 below, shows the options available.
