Pin Function Description
8 Laser Ready output
This bi-directional switched output is internally connected to Pin 13, Output Common,
when the laser is enabled (Ready LED illuminated yellow), indicating that lasing will occur
when a PWM Command signal is applied to Pin 9 and Pin 1. When this output is initially
switched closed, there is a ve-second delay during which lasing is inhibited. This output is
open (high impedance) when the laser is disabled (Ready LED O).
9 PWM Input
Connect your PWM Command signal (+5 VDC, 5 kHz nominal, 100 kHz max, pulse width
modulated) to this input pin to control laser output power. Refer back to Controlling laser
power for further information on laser control signals.
10 Shutter Open Request input
Apply a positive or negative voltage (±5–24 VDC) with respect to Pin 11, Input Common,
to enable lasing. If your system does not supply a Shutter Open Request signal, this input
must be connected to a voltage source in the range of ±5–24 VDC. Refer to Figure 3-7 for
a diagram showing how the Shutter Open Request input is factory-jumpered on the Quick
Start Plug. When a voltage is initially applied to this input, there is a ve-second delay dur-
ing which lasing is inhibited.
11 Input Common
Use this input pin to connect return lines for Remote Interlock, Shutter Open Request,
and Remote Reset/Start Request lines.
12 Auxiliary DC Power Ground
This connection provides a ground (earth) connection for +5 and +24 VDC auxiliary
power outputs. This pin is the only User I/O pin that is connected to chassis ground. Do not
use this pin for grounding if DC power to external I/O circuits is supplied from an external
customer-supplied DC power source.
13 Output Common
Use this pin to complete the return path for output connections (Pin 6, 7, 8, 14, or 15).
The Output Common line is protected by a 0.25 A self-resetting fuse.
14 Shutter Open output
This bi-directional switched output is internally connected to Pin 13, Output Common,
when the Shutter Switch is Open and a Shutter Open Request signal is present (Shutter
indicator illuminated blue), indicating that lasing may be enabled if other operating condi-
tions are met. When this output is initially switched closed, there is a ve-second delay
during which lasing is inhibited. This output is open (high impedance) when the laser is
disabled (Shutter indicator O).
15 Interlock Open output
This bi-directional switched output is internally connected to Pin 13, Output Common,
when remote interlock circuitry is open (Remote Interlock indicator illuminated red), indi-
cating that lasing is disabled. The output is open (high impedance) when lasing is enabled
(Remote Interlock indicator green).
