GV155: All encoder inputs and outputs are designed for TTL level
(RS422 line driver signals).
GV156: Encoder inputs are available with TTL/RS422 format (standard) or with
HTL (15-30V) format against ordering information “Option HTLIN1”. Encoder
outputs are individually adjustable to either TTL/RS422 level or HTL (15-30V)
level by DIL switch setting.
*) Only with model GV155 but not with model GV156
The signal ways shown in the block diagram correspond to all control inputs in LOW or
unconnected state
