2–28 Installation/Wiring
The interface board is jumper selectable to accept a 5V TTL or 12V
DC square-wave with a minimum high state voltage of 3.0V DC
(TTL) or 7.0V DC (12 volt encoder). Maximum low state voltage is
0.4V DC. Recommended wire – shielded, 0.750 mm
2 (18 AWG),
305 m (1000 ft.) or less. Maximum input frequency is 125kHz. See
Encoder & Communications Cabling on page 2–8.

1 For Single-Ended, Single-Channel (pulse) applications, eliminate the B and B (NOT) connections.
Some encoders may label the "A" connection as "Signal."
Important: Correct direction of motor rotation as determined
during start-up (see Chapter 4) may require that the
A or B channel wiring be reversed.
