PROGRAMMING
!RFID HOST
Function This command instructs the Printer to transmit the
specified ASCII string to the Host Machine using
the serial port. When used in conjunction with the
printer "Delimit" command in a label format,
certain variable values can also be returned to the
host.
Explicit Form
RF HOST "ASCII-string-to-send-to-host"
Parameters The data placed inside the " " must be ASCII data.
Data length must be between 0 and 240 characters.
Response The static string is transmitted to the Host
Machine by way of the printer’s serial port.
Command Type RFID Standard Command
Example To Printer:
!RFID HOST “Setting RFID Power-Up Defaults”
!RFID CONFIRM OFF
From Printer:
Setting RFID Power-Up Defaults
NOTE: All CPL-RFID Configuration-Setup Commands
are processed outside the context of a standard CPL
Label-Format (i.e. CPL beginning with a header-line ‘! 0
100 nnn 1’ and ending with ‘END’). So, attempts to use
CPL-RFID Configuration-Setup Commands within a
Label-Format result in being completely and
unabashedly ignored without indication.
Additionally, only static valued strings will print with this
command. Delimited variable substitution is an intra-
label-format function only. For example, variables such
as “$RF_IDNUM$” may not be used.
