4.1.3 Connector J3

J3 contains 25 digital Signals to the SP-ICE-3 Card

Note
The destination of J3 depends on the adapter variant. Pins labelled "Px.n" below should be understood as either "PE.n" or "PD.n", according to the adapter variant.

Disconnect power from the SP-ICE-3 Card before connecting J3 to X403 GpioE or X402 GpioD of the SP-ICE-3 Card with the supplied cable.

A high level on the signal Laser_interface_enable (J3 Pin 1) enables the outputs drivers for LM, GATE, FPS and MEB on J2. When Laser_interface_enable is low, these outputs on J1 are high impedance mode.

A high level on Laser_voltage_enable (J1 Pin 2) enables the auxilary 5V output voltage on J2 Pin 6.

The signals Laser_MIP (J1 Pin 11), Laser_FPS (J1 Pin 19), Laser_GATE (J1 Pin 20) and Laser_LM (J1 Pin 22) are feed through a 5V TTL buffer to J2.

The signals preceded with "XY2_" are the buffered input and output signals to for the XY2-100 connector J1.
