One of the great features of the URI, is that it allows you to<br />
connect an ATMEL AT93C46E-PU (Digikey Part Number AT93C46E-PU-ND)<br />
or equiv. to the URI via the interface connector, thereby allowing<br />
the USBRadio channel driver's working parameters for that radio<br />
in the connector going to the radio (in other words, if you change<br />
URI's or USB positions, the radio parameters stay with the radio and<br />
wont require re-calibration).<br />
<br />
To accomplish this, pins 1 thru 4 of the the 8 pin DIP EEProm are soldered<br />
directly to pins 15 thru 18 (1 to 15, 2 to 16, 3 to 17, 4 to 18) of the<br />
25 pin D-shell connector. Pin 14 is wired to pin 8 (Vcc) and pin 19 is<br />
wired to pin 5 (Gnd) of the EEProm. Pins 6 and 7 of the EEProm are not<br />
used and may be removed.<br />
<br />
Be sure to set eeprom=1 in the stanza for the USB channel in then<br />
/etc/asterisk/usbradio.conf configuration file.</div>N8THN
