Examples
Select camera 1 onto monitor 4
@2,4 <CR> Complete HEX byte string 0x40 0x32 0x2c 0x34 0x0d
@3,1 <CR> 0x40 0x31 0x2c 0x31 0x0d
Once the monitor is selected, any subsequent camera selects relate to this monitor ie to now select camera 16
send the following:
@3,16 <CR>
The current camera can then be controlled using the @5 and @6 commands.
@5 commands are used to start a function and @6 commands are used to stop a function. Only a single function
can be controlled with each command
To Pan Left, Tilt Up and Zoom in, send the following:
@5,3 <CR>
@5,4 <CR>
@5,6 <CR>
Pan and Tilt speeds are sent using the @7 command. 16 speed are supported, 0 being the slowest speed up to
15 as the fastest.
If no speed command is sent following a @5 command then a speed of 1 will be assumed. This prevents the
head from ‘jerking’ on movement start.
Speed Examples
Move Left at increasing speeds
@5,3 <CR> Start Panning Left
@7,1,1 <CR> Slow Pan Speed
@7,5,1 <CR> Increased Pan Speed
@7,10,1 <CR> Even Higher Pan Speed
@7,15,1 <CR> Full Pan Speed
To stop movement in a direction send a @6 command followed by pan/tilt speed 0
To stop moving left send
@6,3 <CR>
@7,0,0 <CR>
Selecting a new camera whilst the current camera is moving will cause the current camera to stop moving before
selecting the new camera.
