Bob,
Inputs 3 & 4 in the default digital mode require a pullup resister to +5 V (10K between Input and +5V works well, as you have done). To change the state of Inputs 3 or 4 when in digital mode, connect Input to GND through a dry contact switch, just like Inputs 1 & 2.
When Inputs 3 & 4 are configured for Analog operation, the analog Input voltage should swing from 0 volts to +5 volts with no pullup resister.
Not specific to EZSrve, Smarthome documents that devices with BoosterLinc can interfere with Insteon powerline traffic and BoosterLinc should be turned off.
