Belt Encoder Interface
For use with conveyor tracking, EJI boards support two independent external belt
encoders through a single, female, 15-pin D-sub connector. The pin assignments
for the Belt Encoder connector are shown in Table 10-3. See Figure 10-2 for a
typical input circuit drawing. Adept strongly recommends using differential
encoder outputs for maximum noise immunity. See the V
+
Language User’s Guide
for more information on setting up and programming a conveyor tracking
application.
NOTE:
Conveyor tracking requires a V

Extensions License, which
can be obtained from Adept.
