The following remote control protocol applies to RS232 and RS485 remote control. The

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 )

0x59 (checksum)
