capture.channel1.port

capture.channel1.port

This command determines the port that should be monitored for user data. This allows the user to attach an external device, such as a keyboard or barcode scanner, and have input captured into the
capture.channel1.data.raw
command. Once the data is in the SGD they can use it as they would any other SGD (this includes functionality that allows users to be sent an alert when an SGD value changes).
The data received on the specified port will be read until the value in
capture.channel1.delimiter
is seen, at which point the data received until (but not including) the delimiter will be stored in
capture.channel1.data.raw
.
For the port specified in
capture.channel1.port
, no data will be sent to any of the parsers on that port. All data received is assumed to be user input that is to be placed in
capture.channel1.data.raw
. To disable the data capture functionality, set
capture.channel1.port
to
"off"
The delimiter will not be stored in
capture.channel1.data.raw
. The port will be shown in the data capture portion of the HZA response. The capture port shall be defaulted to
“off”
by any mechanism (including
^JUF, ^JUA
, and
device.restore_defaults
).

Setvar

To set the port to be monitored for user data:
! U1 setvar "capture.channel1.port" "value"
Values
  • off
    means no data is stored in
    capture.channel1.data.raw
    and all data is sent to the parsers - normal operation
  • serial
    means data is read off the serial port. No data sent to the parsers on this port.
  • usb
    means ata is read off the USB port. No data sent to the parsers on this port.
  • bt
    means data is read off the Bluetooth
    ®
    port. No data sent to the parsers on this port.
  • usb_host
    is not yet supported. Reserved for when usb host is implemented.
Default
"off"

Getvar

To retrieve the printer’s current port being monitored for user data:
! U1 getvar "capture.channel1.port"
Example
This example sets the command value to
"off"
, preventing it from capturing data.
! U1 setvar "capture.channel1.port" "off"
