Re install GUS station (Honeywell TPS)

In our plant has Honeywell TPS installed. Is it possible to transfer one GUS station to another building (600 meters)? Is it possible to extend the output from MAU (RS232 to 485 through an optical fiber line) and establish a station. I think the output of MAU is RS232.
I recommend you to recheck for all of the communication protocol options for your devices. If any, you should find Modbus protocol using RJ45 connection. Just use the ethernet to Fiber Optic converter to get your data for 600 meters communications.
