The Field Bus Modem (FBM) is used for connecting a TankMaster HMI software PC to the TRL/2 Bus.
The FBM 2180 is connected to the PC using either the RS232 or the USB interface (TankMaster version 4.F1 or higher is required for the USB interface functionality).
It is delivered with cables for RS232 and USB connection to the PC. The USB cable also supplies power to the FBM.
A separate power supply cable (included in delivery) is only necessary for the RS232 option.
The FBM has LEDs indicating power on and communication. For the TRL/2 interface, there are front panel switches to set gain and termination if required.
The mechanical mounting is performed using the mounting kit, included in all deliveries, which enables fitting of the FBM to a standard DIN rail.
