NXC-IRS4 Send_Commands (Cont.)
Command Description
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.
PON Turn ON 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 OFF (such as if one turned it off manually at
the front panel), IR function 27 (if available) or IR function 9 is automatically generated in an attempt
to turn the device back ON. If three attempts fail, the IR port will continue executing commands in the
buffer and trying to turn the device On.
If there are no commands in the buffer, the IR port will continue trying to turn the device ON until a
'POF' or 'POD' command is received. If the IR port fails to turn the device ON, 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.
Syntax:
SEND_COMMAND <DEV>,"'PON'"
Example:
SEND_COMMAND IR_1,"'PON'"
Sends power up IR commands 27 or 9 to the IR_1 port.
