INPUT/OUTPUT SIGNALS
Pin 10 Shutter Open Request
Apply a positive or negative voltage (±5–24 VDC) with respect to Pin 11, Input Common, to en-
able lasing. If your system does not supply a Shutter Open Request signal, this pin must be con-
nected to a voltage source in the range of ±5–24 VDC. Refer to the figure below for a diagram
showing how the Shutter Open Request input is factory-jumpered. When a voltage is initially
applied to this input, there is a five-second delay during which lasing is inhibited. Because all DC
power is removed from the laser's RF board when this input is inactive, no lasing can occur until
voltage is applied to Pin 10. See the following table for input circuit specifications.
Important Note: To ensure optimum laser performance, there is a five-second delay imposed
from the time a Shutter Open Request occurs to the time that PWM Command signals are accepted.
Pin 11 Input Common
Use this pin to connect return lines for Remote Interlock, Shutter Open Request, and Remote
Reset/Start Request lines. Refer to the following table for input circuit specifications.
Figure below illustrates how Remote Interlock and Shutter Open Request inputs are factory-jumpered on
the Quick Start Plug to enable lasing for initial testing and troubleshooting purposes.
The figure on the following page illustrates the input circuit's equivalent internal schematic while Table 3-
4 provides v40 input circuit specifications.
