Test Loopback Connector
The following information is used to create a URI Test (Loopback) connector.
Parts
- 25 pin male D-shell connector
- ATMEL AT93C46E-PU (Digikey Part Number AT93C46E-PU-ND) or equivalent for the EEPROM.

Assembly
- 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.
