CAN1 termination (P1)
I-LB+ has included CAN terminating resistor (120 ohm). Close jumper P1 to connect terminating resistor to
CAN bus, open jumper P1 to disconnect terminating resistor.
RS232 or RS485 termination (P2)
I-LB+ has included RS232/RS485 terminating resistor (120 ohm). Close jumper P2 to connect terminating
resistor to RS485 bus, open jumper P2 to disconnect terminating resistor.
Select RS mode (P3)
Jumper P3 selecting RS mode. When jumper P3 is connected to 1-2, RS232 mode is activated. When jumper
P3 is connected to 2-3, RS485 mode is actives.
