For URIx P/N 9095 that uses the CM119A also include the following:
Pin 5 to Pin 10
Pin 6 to Pin 11
Do *NOT* include these connections for the older URI P/N 9080 that uses the CM108.
Remove EEprom pins 6 and 7 (not used).
Use an ATMEL AT93C46E-PU (Digikey Part Number AT93C46E-PU-ND)
or equiv. for the EEProm.
To accomplish this, pins 1 thru 4 of the the 8 pin DIP EEProm are soldered
directly to pins 15 thru 18 (1 to 15, 2 to 16, 3 to 17, 4 to 18) of the
25 pin D-shell connector. Pin 14 is wired to pin 8 (Vcc) and pin 19 is
wired to pin 5 (Gnd) of the EEProm. Pins 6 and 7 of the EEProm are not
used and may be removed.
