Powering the CL-GigE Using an External Power Supply
Another way to power the CL-GigE is with a 12 V external power supply through the 12-pin GPIO
connector. Optionally, you can purchase an external power supply from Pleora (part number 904-3905).
The CL-GigE can optionally supply power to a camera using PoCL. If the CL-GigE is powered by an
external power supply and you supply power to the camera using PoCL, VIN must be in the range of
11.7 V to 13 V to meet the requirements of the
Camera Link Standard
.
External Power Supply — Input Signals
The following table lists the input power signals for the CL-GigE from an external power supply using
the 12-pin GPIO connector.
To power the CL-GigE using an external power supply
1.
Ensure that the Camera Link camera and the CL-GigE are NOT receiving power.
2.
Securely connect the Camera Link cable to the camera and to the CL-GigE.
Ensure that you tighten the screws to prevent the camera from being disconnected accidentally.
Important:
Do not disconnect the Camera Link cable while the camera or CL-GigE are receiving
power.
Tip:
We recommend that you connect the CL-GigE to your computer’s NIC or a GigE switch
before you apply power.
3.
Supply 12 V power to the 12-pin GPIO connector on the CL-GigE.

Unfiltered DC power from an external power supply through the 12-pin GPIO connector.
Reverse voltage protected, up to -30 VDC.
The CL-GigE generates all internal power rails from the VIN signal. A resident common
mode filter allows the input to be unfiltered, directly from a switching wall plug power
supply.

Important Power Sequence Information
To avoid damage to the CL-GigE (and in some cases the connected equipment):
• If you are using GPIO inputs, set the
Differential Type
and
I/O Level
switches BEFORE you connect
equipment and BEFORE you apply power to the CL-GigE.
• Always power up the CL-GigE BEFORE the camera.
• Always power down the camera BEFORE the CL-GigE.
