2.6 Power Supplies

The camera requires a single voltage input (+5V). The camera meets all performance specifications
using standard switching power supplies, although we strongly recommend that you use
regulated linear supplies
When setting up the camera's power supplies follow these guidelines:

WARNING: It is extremely important that you apply the appropriate voltages to your camera.
Incorrect voltages will damage the camera. Protect the camera with a fast-blow fuse between
power supply and camera.

2.7 Control Inputs, Camera Link

The camera accepts control inputs through the Camera Link MDR26F connector. All inputs are
optional. The camera ships in free-running mode.
EXSYNC (Triggers Frame Readout)
EXSYNC is an optional input signal that can be used to trigger the line readout rate. This camera
uses the rising edge of EXSYNC to trigger line readout.
Note: EXSYNC should not be clocked faster than the camera's specified maximum frame rate.
When the constant frame rate register is enabled (default setting), the camera ignores the EXSYNC

External MCLK is an optional signal used to control the data rate.
PRIN
PRIN is an optional input signal used for exposure control (PRIN).

2.8 Data Bus, Camera Link

These signals indicate when data is valid, allowing the data to be clocked from the camera to your
acquisition system. These signals are part of the Camera Link configuration. Refer to the DALSA
Camera Link Implementation Road Map, available at http://vfm.dalsa.com, for the standard
location of these signals:

Protect the camera with a fast-blow fuse between power supply and camera.
Do not use the shield on a multi-conductor cable for ground.
Keep leads as short as possible to reduce voltage drop.
Use high-quality linear supplies to minimize noise.
