Modbus RTU over RS485

1. Connect the serial cable between the serial port of the Teleport and the serial port of the meter.
2. Teleport is configured to use the following Modbus interface configuration. Please configure the meter to use the same settings or let us know if you use a custom configuration:
   • Device address: 1
   • Baud rate: 9600
   • Stop bits: 1
   • Parity: none

Tip

• Better performance can be achieved by using a higher baud rate. Let us know if you configure a higher baud rate on your asset.
