Terminator
*1. Internal terminating resistors are used for the devices at both end of a transmission line.
Close across the terminals DB and TR for the 73VR1100, T2 and T3 for the R1M-GH2.
*2. Install shielded cables to all sections and ground them at a single point.
☛ When connecting other signal types, see the 73VR1100 User's Manual
