3.5Configuring the Modbus Ports
3.5.1Connecting Power for the Configuration
Refer to the installation chapter in this guide for connecting power to your BM85. Connect the source of AC or DC power to the BM85. Do not turn on the power to the BM85 until you set the Modbus port configuration switches and connect the configuration terminal. The switch settings will be sensed when power is applied.
3.5.2Setting the Switches
The BM85 power should be set off at this time. Switches are located on the BM85 rear panel. Figure 10 shows the switch positions and setup.
