Digital logic voltage switch

The digital logic voltage switch lets you set the voltage to either 3.3 V or 5 V (default setting).

To interface with 3.3 V logic, use the 3.3 V setting. To interface with 5 V logic, use the 5 V setting. Refer to the

digital I/O specification on page 31 for the maximum and minimum threshold levels for each setting.

To change the logic voltage, slide the switch left or right with a screwdriver.

Factory default reset button

Press and hold this button for three seconds to restore the factory default network settings on the WEB-TC.

When held for 3 seconds, the POWER LED will turn off for a short time, indicating a reset is in process. When

the POWER LED turns back on, reset is complete and the factory default network settings have been restored.
