5.7.1 Setting the Slave ID on a DX80 Gateway
By default, all Gateways are set to Modbus Slave ID 1.
To change the Slave ID on the Gateway, follow these steps.
1. Single click button 1 to advance between menus. Stop when you reach the DVCFG menu.
2. Press button 2 once at the *DVCFG menu to enter the Device Configuration menu.

network may take up to 20 seconds to re-synchronize.
9. Double-click Gateway push button 2 to return to the Device Configuration (*DVCFG) menu.
10.Click Gateway push button 1 until reaching the *RUN menu option.
5.7.2 Setting the Baud Rate
The baud rate establishes the communication rate between the Gateway and the host system to which it is wired.
Continuing from the previous menu position, follow these steps to set the baud rate.
1. Single-click Gateway push button 1 to move to the next menu option, the BAUD rate.
2. Single-click Gateway push button 2 to display the current setting. Single-click Gateway push button 1 to cycle through
the available options. Stop on the desired setting.
