Pin Function Description
1 PWM Return
Use this input pin as the return side of the PWM Command signal.
2 Remote Reset/Start Request
Apply a positive or negative voltage (±5–24 VDC) with respect to Pin 11, Input Common,
to reset or remote keyswitch the laser. The laser remains disabled while voltage is applied.
Removing voltage from the Remote Reset/Start Request pin causes the laser’s RDY indi-
cator to illuminate and begins a five-second countdown after which lasing is enabled.
3 Remote Interlock
Apply a positive or negative voltage (±5–24 VDC) with respect to Pin 11, Input Common,
to enable lasing. If your system does not use a remote interlock, this pin must be connected
to a voltage source in the range of ±5–24 VDC. Refer to Figure 3-8 for a diagram showing
how the Remote Interlock input is factory-jumpered.
4 + 5 VDC Auxiliary Power
This connection provides +5 VDC for driving external inputs or outputs. The +5 VDC
Auxiliary Power output can source up to 0.5 A and is protected by a 0.5 A self-resetting
fuse. The return (ground) path must be through Pin 12, Auxiliary DC Power Ground.
5 + 24 VDC Auxiliary Power
This connection provides +24 VDC for driving external inputs or outputs. The +24 VDC
Auxiliary Power output can source up to 0.5 A and is protected by a 0.5 A self-resetting
fuse. The return (ground) path must be through Pin 12, Auxiliary DC Power Ground.
6 Laser Active
This bi-directional switched output is internally connected to Pin 13, Output Common,
when the laser is actively lasing (LASE indicator illuminated red). This output is open
(high impedance) when no beam is being emitted (LASE indicator Off).
7 Over Temperature
This bi-directional switched output is internally connected to Pin 13, Output Common,
when laser temperature is above safe operating limits (TMP indicator illuminated red). The
output is open (high impedance) when laser temperature is within operating limits (TMP
indicator green).
