4.5.5 Default/Shorting Plug (JP1 JP2) - 3 Pin Male Connector
If you are having difficulty opening the Web Browser or the Terminal Interface, you can
reset the M&C interface settings. Use the supplied default plug (CNRSHUNT). See
Figure 4-5.
1. Install the default plug across pins 1 and 2 of JP1 and JP2 connectors.
2. Cycle the power.
3. The interface default settings will reset.
Default jumper/shunts are with the supplied connector kit. The default jumper might be installed
between pins 2 and 3.
1. Reposition the jumper across pins 1 & 2.
2. After the default settings have been activated, remove the Jumpers.
