Software Interface: Configuring
the Camera

Using ASCII Commands

All of the camera’s functionality is configurable through its serial interface using the
three letter commands. You can use any terminal program (e.g. HyperTerminal) to send

serial commands to the camera, however, you must comply with following serial
protocol:

8 data bits

1 stop bit

No parity

No flow control

9.6kbps (at power up)

Camera does not echo characters

Command Format

When entering commands, remember that:

A carriage return

<CR>

ends each command.

The camera will answer each command with either

<CR><LF>Error xx: Error Message >

Warning xx: Warning

Message

. The

character is always the last character sent by the camera.

The following parameter conventions are used in the manual:

= integer value

= real number

= member of a set

= string

= tap id

= pixel column number

= pixel row number

Example: to return the current camera settings

gcp

<CR>
