Communicate a Pixhawk Cube with a IR camera using RS232

Hello all, I have to use RS232 and to send commands to a camera from a pixhawk cube, but I am lost. I don know if this is possible, if I need any extra hardware or how to send the following messages:

|Command|Command packet|

|Zoom out |0xFF,0x01,0x00,0x40,0x00,0x00,0x41|
|Zoom in |0xFF,0x01,0x00,0x20,0x00,0x00,0x21|
|Illumination Up |0xFF,0x01,0x00,0x07,0x00,0x48,0x50|
|Illumination Down |0xFF,0x01,0x00,0x07,0x00,0x49,0x51|
|Stop| 0xFF,0x01,0x00,0x00,0x00,0x00,0x01|

I appreciate any help. Thank you in advance.

You have first of all to get your serial ports talking.
The Cube comms is TTL level at 3.3v and RS232 is at 5v.
Logic level converters are plentiful and cheap.

As far as sending commands I think is where the new LUA scripts will shine.
So have a read of the Wiki on LUA scripting.
