R/F Terminal Firmware Upgrades
The R/F Terminal firmware can be upgraded by replacing the EPROM or
by downloading new firmware into the R/F Terminal from your computer.
Replacing the EPROM
The same procedure used to replace the EPROM on the R/F Base or Relay
applies to the R/F Terminal also. Refer to Appendix A; Frequency and
Jumper changes for instructions on opening the Terminal's case.
To replace the R/F Terminal EPROM:
• Open the R/F Terminal and locate the EPROM. The R/F Terminal
EPROM is square and has a paper label on it for identification.
• To remove the EPROM, insert a paper clip leg at each corner with a
groove in it, lifting up on the clip to pry out the EPROM.
• Notice that one corner is blunt. Put the new EPROM in the socket,
lining up the blunt corner of the EPROM with the same blunt corner
on the socket.
• Press it in, and put the case back together, replace the batteries and
turn it on.
• If the first screen comes up correctly-- you're done. Otherwise, you
probably didn't get it seated all the way in. Try again.
Downloading firmware from your computer
The RF Terminal firmware can also be upgraded by downloading a file with
the current firmware into the RF Terminal's flash EPROM using the
LOADER.EXE program or the RF Terminal EPROM Loader Windows
program found on the R/F Terminal Utilities Disk.
If you have received a disk with the latest firmware or have downloaded the
firmware from our website, www.barcodehq.com, download the firmware
into the R/F Terminal using one of the following procedures:
