Output
Circuitry
If the encoder uses less than 12 bits, jumper the
unused input terminals.
Connecting a Differential Output Encoder
Figure 3.7 is the connection diagram for a differential output encoder.
Connect the bit 0 signal line to terminal 1 and the bit 0 line to terminal 2.
Connect bit 1 to terminal 3 and the bit 1 line to terminal 4. Continue in
this way for all encoder channels.
If the encoder has less than 12 signal bits, jumper the unused input
terminals. For example, if you are using a 10-bit encoder, jumper
terminals 19 and 20 and terminals 17 and 18 on the right wiring arm.
