Command Format - Imperx LYNX User Manual

3.3 Command Format

Command strings consist of a command token followed by up to two parameters.
The format of the command string is:
<command> <parm1> <parm2><cr>
In response to the receipt of a command string, the camera will perform the
intended operation and return a response string. Depending on the type of command
received, the camera will return either a 'status' response or an 'info' response. A
'status' response generally reports the success or failure of the camera to perform
the commanded operation. An 'info' response provides specific camera information
requested by user.
The format of the status response string is:
OK<cr><lf>:
Error: <text><cr><lf>:
The format of the info response string is:
<response><cr><lf>:
Important Note: The following applies to software versions 1.57 and lower.
Escape markers were removed from software version 1.58 and higher.
All camera responses are enclosed within a pair an Escape Markers. An Escape Marker
consists of a 6 character string as follows:
<ESC>[<CODE1><CODE2><CODE3><CODE4>
Byte1 = 1B hex ( ESC character )
Byte2 = 5B hex ( [ character )
Byte3-6 = marker codes
For example, in response to a 'gag 1' command the camera will return ( in hex ):
67 61 67 20 31 20 0D 0A
gag 1 ( if echo is on )
Escape Markers are used during camera download and should be ignored otherwise.
Terminal emulator programs ( i.e. HyperTerminal ) are designed to ignore Escape
Markers.
