7.2 Sensor Output Format

Sensitivity Mode

Purpose:

Sets the camera’s sensitivity mode. When using high sensitivity
mode, the camera’s responsivity increases. High sensitivity mode
permits much greater scanning speeds in low light, or allows
reduced lighting levels.

Syntax:

ssm i

Syntax Elements:

i

Sensitivity mode to use.

0

= Low sensitivity mode

1

= High sensitivity mode

2

= Tall pixel mode

Notes:

•

To obtain the current sensitivity mode, use the command

gcp

or

get

ssm

.

•

The

scd

(set ccd direction) command is not available in low

sensitivity mode or tall pixel mode.

Example:

ssm 0

CCD Shift Direction

Purpose:

When in high sensitivity mode, selects the forward or reverse
CCD shift direction, internally or externally controlled. This
accommodates object direction change on a web and allows you
to mount the camera “upside down”.

Syntax:

scd i

Syntax Elements:

i

Shift direction. Allowable values are:

0 =

Internally controlled, forward CCD shift direction.

1 =

Internally controlled, reverse CCD shift direction.

2 =

Externally controlled CCD shift direction via Camera

Link control CC3 (CC3=1 forward, CC3=0 reverse).

Notes:

•

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

gcp

or

get scd.

•

Available in high sensitivity mode only.

•

Refer to Figure 6: Object Movement and Camera Direction
Example using an Inverting Lens, page 11, for an illustration
of when you should use forward or reverse shift direction.

Related Commands:

ssm

Example:

scd 0
