RS232 Control Protocol
Baud Rate: 4800bps, 8-bit data, 1 stop bit
The unit will respond following receiving the command from the server
| Command byte Data byte Checksum byte | |
| Byte#0 Byte#1 Byte#2 | |
| Command byte | Data byte ACK type(from SDI-CVBS-S) | Funtion |
| Oxa0 0x00 | B Get Model Name | |
| 0x01 B Get possible | output resolution number | |
| 0x02 B Get adjustable | video parameter number | |
| 0x03 B Get supported | audio control | |
| Oxa1 0x00 | 0xff A Brightness | Default: 0x80 |
| Oxa2 0x00 | -0xff A Contrast | Default: 0x80 |
| Oxa3 0x00 | -0xff A Saturation | Default:0x80 |
| 0xb0 | 0x00/0x01 | A Output resolution0: NTSC1: PALDefault: 0x00 |
| 0xb1 | 0x00/0x01 | A Audio enable0:off / 1:0nDefault: 0x01 |
Example:
To set the brightness to be the value 0x02
Server sends: 0xa1, 0x02, 0x5d
SDI-CVBS-S replies: 0xa5, 0x96
SDI-CVBS-S => Server command
Type "A" format
| Ack byte | Checksum byte | Note |
| 0xa5 | 0x5b | Means "ACK", the unit received a valid command |
| 0x6a | 0x96 | Means "NAK", the unit received an unknown command or data byte that is out of range |
Type "A" ACK format
| Ack byte | Checksum byte | Note |
| 0xa5 | 0x5b | Means "ACK", the unit received a valid command |
| 0x6a | 0x96 | Means "NAK", the unit received an unknown command or data-byte that is out of range |
Type "B" ACK format
| ACK byte | Length byte | Data byte | checksum byte | |
| Order | Byte#0 | Byte#1 | Byte#2~Byte#N | Byte#N+1 |
| Value | 0x5a | N+2 | 0x00~0xff | 0x00~0xff |
*checksum byte: check sum from Byte#0\~Byte#N+1
Example:
To get model of the unit
Server sends: 0xa0, 0x00, 0x60
The unit will respond 0x5a, 0x0a, '3', 'S', 'C', '-', '0', '2', 'M', 'W', 0xa0
