F&F

The Teleport can connect to the F&F relay products included in the list of supported models below.

Supported models

• MR-RO-1
• MR-RO-4

Modbus RTU over RS485

Note

• The slave ID of the F&F relay is only configurable using Modbus. If more devices need to be connected on a single RS-485 bus, they have to be connected 1-by-1 to have their identifiers changed via Modbus.

1. Connect the serial cable between the serial port of the Teleport and the serial port of the F&F. The RS-485 connection between the Teleport and F&F relay is as follows.

   • D- of the Teleport connects to the connection of the F&F relay marked B.
   • D+ of the Teleport connects to the connection of the F&F relay marked A.

2. Check that the default settings are:

   • Device address: 1
   • Data bits: 8
   • Stop bits: 2
   • Parity: None
   • Baud rate: 9600
