Appendix B: Control panel protocol

Appendix B: Control panel protocol

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

ywhen a delegate or chairman unit is activated,

ywhen a delegate or chairman unit is deactivated,

ya microphone goes into request mode,

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

The control panel sends a control command to the central unit:

ywhen a delegate or chairman unit is to be activated,

ywhen a delegate or chairman unit is to be deactivated,

ywhen the control panel is to be reset (Reset)

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

Bits per second: 19,200

Data bits:

8

Parity: None

Stop bits:

1

Flow control: None

Note!

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

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.
