EEPBus protocol is a universal control protocol for EDSR and EDR (MPEG4) series’ digital video
recorders. Therefore, it may occur that some of the following commands are not available for
all DVR types.

1-1. Sample control code packets
Example 1 : A packet that sends "REC" key to DVR (ID=5)
0x85 (length)
0x00 (Receiver ID high byte)
0x05 (Receiver ID low byte)
0x4B (OPcode = key )
0x08 (DATA1 = "Rec" keycode )
0x5D (checksum)
Example 2 : A packet that sends "PAUSE" key to DVR (ID=4999)
0x85 (length)
0x27 (Receiver ID high byte)
0x07 (Receiver ID low byte)
0x4B (OPcode = key )
0x0C (DATA1 = "Pause" keycode )
0x0A (checksum)
Example3 : A packet that sends "PLAY" key to all DVR (broadcast)
0x85 (length)
0x7f (Receiver ID high byte)
0x7f (Receiver ID low byte)
0x4B (OPcode = key )
0x0B (DATA1 = "Play" keycode )
