DDS 5900 Digital Discussion System

Shure Incorporated

<SP> Space - 0x20 = 32

<CR> Carriage return - 0x0D = 13

<LF> Line Feed - 0x0A = 10

Command lines are terminated by a Carriage Return <CR> or Line Feed <LF> or both. In order to be able to com-

municate with Windows systems, Linux systems or other systems, the CCU understands both types of command

line terminations.

Notice also, there is a space between the command and data. If a command does not carry any data, space is

possible but not required.

The CCU is not sensitive to upper/lower case.

Example:

mic_on 212<CR>

Turn on microphone at seat 212. Command = mic_on, data = 212. The 'mic_on' command carries a seat number

as data.

Command Structure (from DIS-CCU to External Control)

Command lines out of the DIS-CCU are just as simple:

<SP> Space - 0x20 = 32

<CR> Carriage return - 0x0D = 13

<LF> Line Feed - 0x0A = 10

Again, to satisfy most systems, the CCU terminates command lines by including both <CR> and <LF>.

Seat Numbering

Discussion Units are identified by means of a seat numbers. Each Discussion Unit is assigned a seat number. This

is done automatically for all discussion units, when they are connected to the DIS-CCU. The DIS-CCU Browser in-

terface is used to change seat numbering.

Seat numbers must be in the range from 1 to 65535.

DIS-CCU Reply to Commands

Generally, a command from an external application is replied to by the CU. But, reply to a command is produced

only if actions are taken by the CCU due to the command.
