RS485 Fiber Modem

The AN-FM-RS485 family are standalone and rack mountable fiber 1 x 485 modems available in a number of different models, with AC or DC power supplies built-in. The AN-FM-RS485 family of modems may be applied in point-to-point applications or they may be installed and linked to a centrally located AN-CH01 or AN-CH03 chassis.
