UID ECHO
The “UID Echo” command offers an easy way to test output to the LCD, Keyboard Wedge, and VCOM
port. Issue “UID Echo” followed by a space. The first 20 characters of text following the space will be
echoed to the top line of the LCD, and the entire text will be echoed to the Keyboard Wedge and the
VCOM ports.
Information:
The Keyboard Wedge function and LCD Display must be set to ON
in order for the text following the ECHO command to appear.
Change Input Delimiters “UID IDLM”
The UID IDLM command is used to change the UBS-200L input delimiters. This is only necessary if a
legacy host program requires it. If custom input delimiters to the UBS-200L are needed, please contact
UI Devices for proper use of the UID IDLM command.
Note:
Improperly setting the input delimiters through the “UID IDLM”
command can cause the UBS-200L to become unresponsive to
host commands. Only make adjustments to this parameter if
instructed to do so by UI Devices.
Change Output Delimiters “UID ODLM”
The UID ODLM command is used to change the UBS-200L output delimiters. This is only necessary if a
legacy host program requires it. If custom output delimiters from the UBS-200L are needed, please
contact UI Devices for assistance in using the UID ODLM command.
Change Keyboard Wedge Delimiters “UID KWDLM”
The UID KWDLM command is used to change the UBS-200L output delimiter keystrokes. This is only
necessary if a legacy host program requires it. If custom output delimiter keystrokes from the UBS-200L
are needed, please contact UI Devices for assistance in using the UID KWDLM command. Available
keystrokes are summarized in Table 12 of the “Universal Serial Bus (USB) HID Usage Tables.”
Change Keyboard Wedge Separator Keystroke “UID KWSPR”
The UID KWSPR command is used to change the UBS-200L keystrokes that separate the transponder ID
from the accompanying transponder data. This is only necessary if a legacy host program requires it. If
custom data separator keystrokes from the UBS-200L are needed, please contact UI Devices for
