2.4 External Interfaces
●
Serial Interface (COM1)
CAUTION
• Make sure to turn off the power to the HG5G/4G/3G/2G-V before wiring each interface or
switching the terminating resistor selector switch.
• The serial interface (COM 1) is used only for the interface of RS232C or RS422 / 485. Wiring both
interfaces will result in failure of the HG5G/4G/3G/2G-V. Wire only the interface used.
• Note that the serial interface (COM2) can be used as the RS232C and RS422/485 interfaces at
same time.
