The i50 firmware can be updated by connecting a programming cable to the RJ-45 Prog connector
on the front panel, and using the Rabbit Field Utility (RFU) program. Programming cables may be
purchased from Datalink Systems, or made up using the pin outs defined in section 4.3. The RFU
program is available at http://www.datalinksystemsinc.com/download.html. Figure 9 shows the
