How can the Niagara G3 ENC platform be accessed if the user name and password have been forgotten?

Environment

Niagara G3 ENC

Cause

Forgot username and password for the Niagara G3 ENC.

Resolution

1. To connect via the serial port of the ENC you will need a UNCC-405, an Ethernet cable 7' or less, and Hyperterminal (or another terminal program).
2. In the upper right corner of the ENC-520 is a block of four pins marked J4 Mode. Using one of the bias jumpers from the board, temporarily short the front two pins. Using the UNCC-405 and short Ethernet cable connect the laptop to serial port one of the ENC. Open HyperTerminal and configure a connection as 57600, 8, none, 1, no flow control.
3. Reboot the ENC. When this appears: "Press ESC to restore factory default username and password...", go ahead and press the ESC key. Enter "y" when prompted to force the platform user name and password back to "tac" and "niagara".
4. After using WorkBench to verify the user and password have been changed, remove the jumper and disconnect the serial connection.
