Pin 8 Laser Ready
This bi-directional switched output is internally connected to Pin 13, Output Common, when the laser is
enabled (Ready indicator On), 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 five-second delay during which
lasing is inhibited. This output is open (high impedance) when the laser is disabled (Ready LED Off). Refer
to Table below for output circuit specifications.
Pin 13 Output Common
Use this pin to complete the return (ground) path for any output connection (Pin 6, 7, 8, 14, or 15). The
Output Common line is protected by a 0.25 A self-resetting fuse.
Pin 14 Shutter Open
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 LED blue), indicating that lasing
may be enabled if other operating conditions are met. The output is open (high impedance) when the
Shutter Switch is Closed or the Shutter Open Request signal is removed. When Shutter Open output closes
(Shutter LED Off), there is a five-second delay until PWM inputs are recognized. Refer to the below table
for output circuit specifications.
Pin 15 Interlock Open
This bi-directional switched output is internally connected to Pin 13, Output Common, when remote
interlock input circuitry is open (Remote Interlock LED red), indicating that lasing is disabled. This output
is open (high impedance) when the laser is enabled (Remote Interlock indicator green). When this output
is initially switched open, there is a five-second delay during which lasing is inhibited. See the following
tables for output circuit specifications.
Following figure illustrates the output circuit’s equivalent internal schematic and the following provides
f201 output circuit specifications.
