The following wiring examples shows connections between a line-driver en-
coder (Am26LS31-compatible) with outputs A, B, Z and inputs A, B, and Z.

The following wiring example shows connections between an open-collector
encoder and an Encoder Adapter (C500-AE001), and between the Encoder
Adapter and inputs A, B, and Z. Connections should be wired so that Counter
Unit inputs go ON when encoder outputs go ON. Because the C500-AE001
Encoder Adapter uses an Am26LS31-compatible line driver, high voltage is
impressed on the positive terminal and low voltage is impressed on the nega-
tive terminal when the output is high.
