•
RS-422 (5V): Two differential channels (A+/A- and B+/B-) are used as input from
the encoder to the camera. The signal swing is 5 V. The maximum encoder fre‐
quency is 2 MHz.
•
HTL (24 V): Two single-ended channels (A and B) are used. The signal swing is 24
V. The maximum encoder frequency is 400 kHz.
To configure the encoder type in the user interface, see "Setting the encoder type and
encoder mode", page 66.
