Encoder Wiring
The Q1 module interfaces only to quadrature encoders with 5 V Differential Line Driver
(RS-422) signals. Single-ended line drivers (TTL) are not supported due to low noise
immunity.
Use twisted pairs and shielded cables for the A and B signals. Always install the
termination jumper to maintain signal integrity. The termination jumper adds a 249Ω
resistor between the + and - inputs.
The Reg input is compatible with signal levels from 12 to 24 V. It draws 2.7 mA max and
turns on when the voltage across the input is greater than 6 V. The polarity is
unimportant.
