8 Command Channel Primer
8.1 Command Channel Commands
All iVu command channel request command frames use the following syntax:
>> command group item value
<EOF>
Notes
<EOF> is the end-of-frame delimiter. See below for a description.
All commands are in ASCII and are case-insensitive
command
An action to be performed on a particular iVu group; for example, get, set, do, login, or logout.
group
Identifies the iVu group that the command should act upon; for example, info, system, trigger, or bcr_input.
item
Further qualifies the action by specifying an item within the identified group; for example, comparedata or status.
value
For set commands, this identifies the data that must be set for the specified group item.
Note: Item is not used with get commands.
<EOF>
Identifies the end-of-frame for the command so that the iVu knows to begin processing. The iVu will return a response
that includes the end-of-frame delimiter. The options for the <EOF> are set in the iVu Serial I/O menu, and are as
follows:
• <comma>
• <colon>
• <semicolon>
• <CR>
• <CR><LF>
• <LF><CR>
• <ETX>
NOTE: When data is displayed on iVu screens such as the Port Status screen,
printable delimiters are displayed as expected. Non-printable characters, such
as <CR> are displayed in hex notation (\x0D).
8.1.1 Command Flow
The command flow should be such that a new command request should not be issued until the iVu command channel acknowledges the
previous command request.
