RAYLASE 3-Axis Subsystems for Laser Beam Deflection
MN025 / v2.1.0
For subsystems with digital interface only
4.6.5
Digital output
The linear translator module uses the 25-pin D-SUB female connector to transmit data to the
deflection unit and supply it with power. All signals are compatible with RAYLASE's extended
function XY2-100 standard.
