Line Trigger, Line Selection

When LineRateMode is PULSE or CONVERT, the line trigger signal originates from an external motion encoder device. In that case line trigger input port(s) must be selected.

The selection is performed in two steps:

LineTrigCtl

Description

Targeted type of motion encoder device

DIFF

Single differential high-speed input port compatible with EIA/TIA-422 signaling

Single output RS-422 compatible incremental motion encoder

DIFF_PAIRED

Dual-output RS-422 compatible phase quadrature incremental motion encoder

ISO

Single isolated current loop input port compatible with TTL, +12V, + 24V signaling

Single output incremental motion encoder

ISO_PAIRED

Pair of isolated current loop input ports compatible with TTL, +12V, + 24V signaling

Dual-output phase quadrature incremental motion encoder
