2.6 Power Supplies

The camera requires a single voltage input (+5V). The camera meets all performance
specifications using standard switching power supplies, although well-regulated linear
supplies provide optimum performance. See section 1.7 Camera Performance
Specifications for current requirements.
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. Refer to section 3 for more
information on setting frame rates and exposure times and camera modes.
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

External MCLK
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:

PRELIMINARY
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.
