Appendix A: Camera control protocol

Appendix A: Camera control protocol

The SDC 8000 conference and interpretation system supports camera control. The central unit sends a control command to the connected camera control:

ywhen a delegate or chairman unit is activated,

ywhen a delegate or chairman unit is deactivated,

ywhen all active microphones are deactived one after the other,

ywhen all active microphones are deactived simultaneously (priority function),

yevery 5 seconds for synchronization.

These commands are evaluated by the camera control which then automatically aims the camera at a speaker and adjusts the focus.

The camera control must be connected to the SDC 8000 CU central unit’s COM 2 interface (RS 232 connection). The settings for the communications port for camera control are:

Bits per second: 19,200

Data bits:

8

Parity: None

Stop bits:

1

Flow control: None

Note!

In order to activate camera control on the central unit, you have to purchase the serial output license SDC 8000 S-SO (Cat. No. 9855)

The syntax of the commands

All commands sent by the SDC 8000 CU central unit start with a “%” sign. The last character is a character which states the end of the transmission. Just before the end-of-transmission character, there are four characters within the command sent to the camera control which account for the CRC checksum.

STX “%”	data	CRC	ETX
Start of	Data of the	16 bit sum of the	End of
Transmission	command	ASCII characters	Transmission
Character		between STX and	Character
(0x25 = “%”)		CRC	(0x0D)

The CRC checksum is in uppercase hexadecimal form while all other numbers are in decimal form.
