4.2.2 Connector J3 |
J3 incorporates 25 digital signals to the SP-ICE-3 Card
Disconnect power from the SP-ICE-3 Card before connecting J3 to X402 GpioD of the SP-ICE-3 Card with the supplied cable.
Note that all signals on J3 are low active, except for the alarm signal.
If there is no interface present, the pull-up resistors on the SP-ICE-3 Card will make the alarm signal appear active, and all other signals inactive.
The J3 alarm signal is generated by OR-ing together all the alarm signals from the laser on J1.
The six alarm signals can be individually enabled and/or inverted via the SPI shift register when Universal Laser Mode is selected with the dip-switch S1.
Otherwise, the default for the specific laser type applies.
