7.1. RS-232C control.

All configuration of the CV-A11 camera is done via the RS-232C port. The camera can be set up from a PC running terminal emulator software, or using JAI´s camera control software.

Below is the description of the ASCII based short command protocol.

Transmit setting to camera:

NN=[Parameter]<CR><LF> (NN is any kind of command. Capital or small letters.)

To have all communication visible on the emulator screen, start with:

EB=1<CR><LF>

The camera answers:

COMPLETE<CR><LF>

Transmit the following to see the current parameter for a command:

NN?<CR><LF> (NN is any commands with parameters.)

The camera answers: NN=[Parameter]

Transmit the following to see the current camera settings:

ST?<CR><LF>

The camera returns the current parameter settings.

Transmit the following to get command list help:

HP?<CR><LF>

The camera returns a complete command list.

Unknown commands send to camera: (XY is unknown command).

XY=1<CR><LF>

The camera answers: 01 Unknown Command!!<CR><LF>

Invalid parameters send to camera: (99 is invalid parameter for SH).
