  • Add the following resistors:
Connection Notes (as applicable)
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:
Connection Notes (as applicable)
Pin 5 -> Pin 10 Do *NOT* include for the older URI P/N 9080 that uses the CM108
Pin 6 -> Pin 11 Do *NOT* include for the older URI P/N 9080 that uses the CM108

Assembly

  1. 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.
  2. Pin 14 is wired to pin 8 (Vcc) and pin 19 is wired to pin 5 (Gnd) of the EEPROM.
  3. Pins 6 and 7 of the EEPROM are not used and may be removed.
