Overview The family of AFO485 fibre optic modems and RF0485 fibre optic repeaters allow the transmission of RS232/RS485/RS422 asynchronous data or a CAN bus via multimode or single mode fibre optics. Fieldbus network The units allow the fibre optic transmission of PROFIBUS DP, MODBUS, UNITELWAY, SYSMACWAY, and the majority of asynchronous protocols, as well as the extension of a CAN network.

On each RFO485, the asynchronous interface used can be different; for example, the first modem can be connected to the PC using the RS232 interface while the second AFO485 can be connected to a PLC using the RS485 or RS422 interface.
The Transmission failure contact closes as soon as the modulation is lost on one of the two lines to which the repeater is connected or if the unit is powered off. The corresponding led ( line 1 or 2) is extinguished. AFO485 and RFO485 USER MANUAL ref 9011509-01 Page 21...
