Polycom Vortex EF2280 User Manual

4.2. Device ID
Two numeric characters are used to indicate the device ID. The Vortex can be configured for device IDs from
'00' to '07'. Note that even though the device ID is less than 10, the leading '0' must be included. Device ID '**'
can be used to send a command to all device IDs simultaneously. Some examples of using wildcard characters
are given below.
● 'F**' broadcasts to all EF2280 devices that are linked together.
● '*07' broadcasts to all devices with device ID 07 (this format is not commonly used).
● '***' broadcasts to all devices that are linked together.
4.3. Command Name
The command name can be from 1 to 7 characters long. Command names will be specific to device types. In
other words, the EF2280 has its own command set, which is different from the EF2241's, which is different from
the EF1210's, etc. There are some commands, such as 'PING', that are common among all the various command
sets.
4.4. Command Data
The command data is a series of 0-64 characters containing payload data for the command. Obviously, the
command data will be specific to the command type. note that the maximum number of payload characters for
the EF200 and EF1210 is 32, but the Vortex devices support up to 64 characters in the payload. This increase
was necessary to accommodate the matrix gain and macro/preset commands.
4.5. Command Terminator
The command terminator is a single character indicating the end of a command. ASCII 13 (^M) was chosen as
the terminator to allow manually typing commands using a simple text terminal.
4.6. Examples
In the following examples, Vortex commands are enclosed in single quotes, 'like this'. Also, the terminator
character is not explicitly shown, but its presence is implied.
Consider the command '***PING'. The device type and ID for this command are wildcards, thus the command
will be sent to all devices. The command name in this case is 'PING', and there are no data characters (payload).
Note that the 'PING' command is supported by all of the Vortex devices, thus broadcasting the command to all
devices makes sense.
Consider the command 'F**GAINIA10'. The device type for this command is 'F' and the device ID is a wildcard,
thus the command will be broadcast to all EF2280 devices linked together. The command name in this case is
'GAINIA' and the command data (payload) is '10'. This command sets the gain on input A of all connected
EF2280's to 10 dB.
Command Effects
***PING
Requests PONG response from all linked Vortex devices.
F**GAINIA10
Sets the gain on input A of all connected EF2280 devices to 10 dB.
