4 HG2G-5T, HG1G
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 (100Ω) between RDA and RDB.
Terminating Resistor Selector Switch (for RS422/485 interface)
• 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.
