About the JANUS Configuration Files
When the JANUS RF device performs a cold boot, it looks for a configuration
file *.INI, whose path is specified in the AUTOEXEC.BAT file. The *.INI file
that you use depends on which software you install on your JANUS device.
J24TE.INI If you install Intermec TNVTxxx, 3270, or 5250 terminal emulation
software, this configuration file is automatically loaded in the DRIVEC
subdirectory.
JANUS.INI If you install Novell TVNTxxx or NetWare Client, you need to
create this configuration file. Use IC.EXE to create the JANUS.INI file and then
you save it to drive E. If you do not want to lose the configuration file when
you cold boot the device, you can put the JANUS.INI file in the DRIVEC
subdirectory.
Remember to update your AUTOEXEC.BAT file with the correct path name of
the new JANUS.INI file.
To load the JANUS.INI file
1. Create a configuration file that you want to load whenever the reader
performs a cold boot.
2. Save this configuration file as JANUS.INI.
3. Copy the JANUS.INI to drive E on the device.
Note
: Since drive E is initialized on a cold boot, you will lose JANUS.INI if you
perform a cold boot on the device. If you want to put the JANUS.INI file on drive
C, use Auto-Loader or MkImage/PutImage to update drive C. Refer to your
JANUS user’s manual for more information.
4. At the DOS prompt on the device, load the configuration file by typing:
IC /L E:\JANUS.INI
Using RF Communications
Once your RF system is configured for RF communications, you can begin
collecting and transmitting data using your JANUS RF device. When you
transmit data using the JANUS RF device, the information is first sent to its
radio buffer. The data is then sent on to the access point and then to the host.
If the RF network goes down, you can continue to collect data until the radio
buffer is full. When the buffer is full, the application returns a communication
timeout status. The actual status response depends on what language you used
to develop the application.
