ahah, good question. the exp bd grabs the 9v motor power for the servos, sonar, and 9v lego sensors. if you're not using any of these, you could leave connector off the exp bd and you'll have no probs. if these are important, you need to reconnect (...)

The modulation frequency of the IR diodes must match the sensor (depending on exact part number, around 38 KHz) within +/- 3 KHz. As you move away from the center frequency, detection drops off sharply. Are you able to confirm the modulation (...) (28 years ago, 23-Feb-99, to lugnet.robotics.handyboard)
