Serial Interface (COM2)
Use applicable cables for wiring and recommended ferrules (made by Phoenix Contact or Weidmüller) as follows.
• Terminating Resistor Selector Switch (for RS422/485 interface)
When using RS422/485 interface, set the Terminating Resistor Selector Switch to the ON side. This will connect the
internal terminating resistor (120Ω) between RDA and RDB.
●
Expansion Module Interface (EXT)
IDEC MICROSmart expansion modules can be connected to the HG5G/4G/3G/2G-V.
Refer to Chapter 30 “1.2 Applicable Expansion Modules” on page 30-2 for the number, the types and the combination
of the expansion modules that can be installed.

Only one ferrule can be inserted into a terminal hole.
Please set another terminal block in the vicinity of MICRO/I and connect SG when using "RS232C" and
"RS422/485" requiring crossover wiring at the same time.
Separate the communication cables so that they do not affect each communication waveform when using
RS232C and RS422/485 at the same time.
