HD1600V2 Serial Protocol, Version 1.4, 10/30/13

Command Syntax

The Error Response

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

If something is wrong with the command, you will get an error response. Which is

^!<error_number>$

which is the ‘!’ followed by an error number (in ASCII), followed the ‘$’ character.

For instance ‘2’ is not allowed as a parameter in the ‘P’ (power) command, so:

^P 2$ -> Command sent to A/V switch

^!2$ <- Error response to an out of range parameter

which indicates there was an out of range parameter.

The following are the Error Response codes that can be returned by the HD1600V2:

1 - Unrecognized command.

2 - A parameter was out of range.

3 - Syntax error, or a badly formed command.

4 - Reserved.

5 - Too many or too few parameters.

6 - Device busy, cannot process command.

7 - Buffer overflow.

8 - Command not valid if device is not powered on.

2xx - Error initializing the HDMI subsystem.

And some more detailed descriptions of their meanings:

Error 1 - The command given was not recognized as a HD1600V2 command. Commands are case

sensitive and in the HD1600V2, all commands are upper case.

Error 2 - One of the parameters given was too large, or too small, the command will be ignored.

Error 3 - Something was wrong with the command's syntax. There was possibly extra data at the end

of the line, or non-decimal data as part of a parameter.

Error 4 - Reserved.

Error 5 - The number of parameters given does not match the number allowed by this command.

Error 6 - To prevent conflicts between the front panel Setup Mode and the serial port settings, when

the HD1600V2 is in the Setup Mode, many parameters become read only and any attempt at

writing them will return Error 6.

Error 7 - An internal buffer has overflowed, for instance more than 16 key codes were sent as part of

the “Key Emulation” command.

Error 8 - Power to the device must be ‘ON’ before this command is allowed.

Error 2xx - An error occurred while initializing the HDMI sub-section.

The Query Response

The query response is sent by the HD1600V2 to indicate a setting has changed, or as a response to a

query command. The query response string consists of the ‘=’ character followed by the command

string of the command being queried.

For instance, in the case of the power command:

^P ?$ -> Send a power request command to the A/V switch

1 2 ... 21 22 23 24 25 26 27 28 29 30 31 ... 45 46
