RAYLASE AXIALSCAN - Digital interface

Functional description Chapter 4
MN025 / v2.1.0 3-Axis Subsystems for Laser Beam Deflection 35
For subsystems with digital interface only
4.7.3 Digital interface
The deflection unit uses the 25-pin D-SUB female connector to receive signals and its power
supply from the linear translator module. All signals are compatible with RAYLASE's extended
function XY2-100 standard. Refer to the following connection table:
