RM Port Terminators
The three RM ports have an RS-485 Terminator switch that is normally on. You
will usually leave these switches in the default position. The RM reader bus is a
half duplex RS-485 connection that must have a terminator at each end of the
bus. When the switch is on the iSTAR Edge provides the 110 ohm terminators.
The other end of the bus is terminated by a switch in the RM4, RM4E, I8, I8-CSI,
or R8.
