DALSA

Setting the Camera Link Mode

Purpose:

Sets the camera’s Camera Link configuration, number of Camera
Link taps and data bit depth. Refer to the tables on the previous
pages to determine which configurations are valid for your camera
model and how this command relates to other camera configuration
commands.

Syntax:

clm m

Syntax Elements:

m

Output mode to use:

0

: Base configuration, 1 taps, 8 bit output

1

: Base configuration, 1 taps, 12 bit output

2

: Base configuration, 2 taps, 8 bit output

3

: : Base configuration, 2 taps, 12 bit output

Notes:

•

To obtain the current Camera Link mode, use the command

gcp

or

get

clm

.

•

The bit patterns are defined by the DALSA Camera Link
Roadmap available at

www.dalsa.com/mv

.

7.3 Exposure Mode, Line Rate and Exposure Time

Overview

You have a choice of operating in one of seven modes. The camera’s line rate
(synchronization) can be generated internally through the software command ssf or set
externally with an EXSYNC signal, depending on your mode of operation. To select how
you want the camera’s line rate to be generated:

1.

You must first set the camera mode using the

sem

command.

2.

Next, if using mode 2, 7 or 8 use the commands

ssf

and/or

set

to set the line rate and

exposure time.

Setting the Exposure Mode

Purpose:

Sets the camera’s exposure mode allowing you to control your
sync, exposure time, and line rate generation.

Syntax:

sem i

Syntax Elements:

i

Exposure mode to use. Factory setting is

7

.

Notes:

•

Refer to Table 14: Spyder 3 CL Exposure Modes for a quick
list of available modes or to the following sections for a more
detailed explanation.

•

To obtain the current value of the exposure mode, use the
command

gcp

or

get sem
