Remote Interlock Connector
The laser is equipped with a remote interlock connector that prevents current flow through the diode when the circuit
is open. After the remote interlock connector has been opened the laser will need to be reset by disconnecting from
and then reconnecting to the power supply in order to start again, or toggling the key switch. Alternatively, it can be
re-
started using the ‘clear fault’ and ‘laser on’
commands, see Section 8.4 for further details. The signal level is
between 0V and +5V with a pull up resistor, and the current required to ground the remote interlock connector is 5
mA. The time delay in the hardware is <1ms, but after filtering by the firmware the reaction time is extended to <
20ms.
06-MLD
The remote interlock connector is a 2.5 mm female stereo (TRS) audio socket. The ring and sleeve (see figure) must
be connected for the laser to operate. To use the remote interlock connector with an external switch, connect a stereo
plug instead.
06-DPL
In OEM configuration the remote interlock connector is located at pin 1 and 2 of the Molex connector on the back side
of the laser head. To close the remote interlock connector with an external switch, connect to pin 1 and 2 of the Molex
plug.

In CDRH configuration the remote interlock connector is located on the key control box and a 3.5 mm mono plug is
provided to short the circuit. To use the remote interlock connector with an external switch a 3.5 mm stereo plug is
required. The ring and sleeve (see figure) must be connected for the laser to operate.
