Pin 1 to Pin 7

Pin 2 to Pin 3

Pin 4 to Pin 8

Pin 11 to Pin 24

Pin 14 to EEProm Pin 8

Pin 15 to EEProm Pin 1

Pin 16 to EEProm Pin 2

Pin 17 to EEProm Pin 3

Pin 18 to EEProm Pin 4

10K Resistor between Pins 21 & 22

10K Resistor between Pins 21 & 23

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.
