IR/Serial Send_Commands (Cont.)
Command Description
GET BAUD
Get the IR port’s current
DATA mode communication
parameters.
The port sends the parameters to the device that requested the information.
Only valid if the port is in Data Mode (see SET MODE command).
The port responds with:
<port #> <baud>,<parity>,<data bits>,<stop bits>
Syntax:
SEND_COMMAND <DEV>,"'GET BAUD'"
Example:
SEND_COMMAND IR_1,"'GET BAUD'"
System response example:
PORT 9 IR,CARRIER,IO LINK 0
GET MODE
Poll the IR/Serial port's
configuration parameters and
report the active mode
settings to the device
requesting the information.
The port responds with: <port #> <mode>,<carrier>,<io link channel>.
Syntax:
SEND_COMMAND <DEV>,"'GET MODE'"
Example:
SEND_COMMAND IR_1,"'GET MODE"
The system could respond with:
PORT 4 IR,CARRIER,IO LINK 0
IROFF
Halt and Clear all active or
buffered IR commands being
output on the designated
port.
Syntax:
SEND_COMMAND <DEV>,"'IROFF'"
Example:
SEND_COMMAND IR_1,"'IROFF"
Immediately halts and clears all IR output signals on the IR_1 port.
POD
Disable previously active
'PON' (power on) or 'POF'
(power off) command
settings.
Channel 255 changes are enabled. This command is used in conjunction with
the I/O Link command.
Syntax:
SEND_COMMAND <DEV>,"'POD'"
Example:
SEND_COMMAND IR_1,"'POD"
Disables the 'PON' and 'POF' command settings on the IR_1 device.
POF
Turn Off a device connected
to an IR port based on the
status of the corresponding
I/O Link input.
If at any time the IR sensor input reads that the device is ON (such as if
someone turned it on manually at the front panel), IR function 28 (if available)
or IR function 9 is automatically generated in an attempt to turn the device back
OFF. If three attempts fail, the IR port will continue executing commands in the
buffer.
If there are no commands in the buffer, the IR port will continue executing
commands in the buffer and trying to turn the device OFF until a 'PON' or 'POD'
command is received. If the IR port fails to turn the device OFF, a PUSH and
RELEASE is made on channel 254 to indicate a power failure error. You can
only use the 'PON' and 'POF' commands when an IR device has a linked
I/O channel. Channel 255 changes are disabled after receipt of this command.
You can only use the 'PON' and 'POF' commands when an IR device has a
linked I/O channel.
Syntax:
SEND_COMMAND <DEV>,"'POF'"
Example:
SEND_COMMAND IR_1,"'POF'"
Sends power down IR commands 28 (if present) or 9 to the IR_1 device.
