1. Overview Installation & wiring
z Wiring for External Input
External Input is a trigger input used to turn Read Request ON/OFF.
External Input will operate given the following voltage input (VIL:0-5V, VIH: 15-28.8V).
Refer to the following example prior to wiring the WB2F.
Communication Unit
Input to
the WB2F
Caution Caution
Miswiring may cause damage to internal circuitry.
Use an AWG16 to 24 Cable for wiring.
z Wiring for External Output
External Output is used to determine read success/read failure during read operations.
Refer to the following example prior to wiring the WB2F.
