Command Syntax

Command Syntax

Command Syntax

The ClarityAudio serial command set uses an ASCII based protocol and a terminal emulator can be
used to test the serial port of the ClarityAudio.

Each serial command is formatted as:

^CMD param1,param2,...$

Where:

^

= All commands and responses start with the ‘^’ character.

CMD

= The name of the command.

param

= Any number of parameters can follow a command.

$

= All commands and responses end with the ‘$’ character.

For instance the name of the command to turn power on / off is ‘

P

’ (must be capitalized) therefore, to

turn on the ClarityAudio send:

^P 1$

->

Command sent to the A/V switch

^+$

<-

Acknowledgment indicating valid command

^=P 1$

<-

Response from the A/Vswitch for new setting

to turn off the ClarityAudio send:

^P 0$

->

Command sent to the A/V switch

^+$

<-

Acknowledgment indicating valid command

^=P 0$

<-

Response from the A/V switch for new setting

N

OTE

: Only the characters between ‘^’ and ‘$’ are valid, any characters sent before the ‘^’ or after the ‘$’

will be ignored.

N

OTE

: By default, the ClarityAudio adds a carriage return and a line feed to the end of its responses, after

the ‘$’. This makes testing with terminal software easier. Since they are outside the ‘^’ and ‘$’ char-
acters, they should be ignored by software drivers. If desired, this behavior can be disabled. (See:
‘XS’ Control Settings” on page 30
)

Command Responses

Type of Responses and Timing Information

There are three different types of responses: Acknowledgements, Errors and Query Strings.

By default, the ClarityAudio will always respond to a command, there are no “time-out” modes, if you
send a command and don’t get a response within 100ms, something’s wrong with the connection.

The Acknowledgement Response

Every command will be followed by an acknowledgement or error response.

Anytime you issue a command and there are no errors, you will receive the acknowledgement
response. Which is:

^+$
