Serial communication
Chapter 12
Data communication
The fibre optic SPA/IEC port can be connected point-to-point, in a loop, or with a star coupler.
The incoming optical fibre is connected to the Rx receiver input and the outgoing optical fibre
to the Tx transmitter output. The module is identified with a number on the label on the module.
The electrical RS485 can be connected in multidrop with maximum 4 terminals.
1.7.2
Design, LON
The serial communication module for LON is placed in a slot at the rear of the Main processing
module. One of the following options is available for serial communication:
•
two plastic fibre cables; (Rx, Tx) or
•
two glass fibre cables; (Rx, Tx)
The type of connection is chosen when ordering the terminal.
The incoming optical fibre is connected to the Rx receiver input and the outgoing optical fibre
to the Tx transmitter output. The module is identified with a number on the label on the module.
