3.4 External Interfaces
●
Serial Interface
Use applicable cables for wiring and recommended ferrules (made by Phoenix Contact) as follows.
Using RS422/485 interface
• For HG2G-5T, if you set the Terminating Resistor Selector Switch to the ON side, this will connect the internal
terminating resistor (100
Ω
) between RDA and RDB.
Terminating Resistor Selector Switch
• HG1G is not equipped with terminating resistor. Insert a terminating resistor of an appropriate value (about 100 to
120 Ohm, 1/2 W minimum) between terminal number 8 (RDA) and terminal number 9 (RDB), if necessary.
CAUTION
Make sure to turn off the power to the HG2G-5T, HG1G before wiring each interface or switching the
terminating resistor selector switch.
