Hi Guy's

I have Played with alot od Ascii RS232 devices, but cannot make sense of my Everfocus DVR.

For instance REC to DVD with id 5

0x85 (length)
0x00 (receiver id high byte)
0x05 (receiver id low byte)
0x4B (OPcodekey)
0x08 (Data key = rec)
0x5d (checksum)



Play Code is 0B so is bellow correct or will check sum change?

0x85 (length)
0x00 (receiver id high byte)
0x05 (receiver id low byte)
0x4B (OPcodekey)
0x0B (Data key = Play)
0x5d (checksum)


Now if i put this into my pronto as a hex code i cant seem to get it to work. below is and example for record inputed into pronto
85 00 01 4B 08 5d

Do i need to work out a check sum? i have tried for hours...

Please help.


Thanks
Daniel
