Digital multimeter having remote display with automatic communication binding

Apparatus comprising:

• a first device and a second device each having control circuitry, IR interface circuitry and RF transceiver circuitry, said control circuitry having associated memory for storing an address of a current RF communication partner;
• said first and second devices having a respective first address and second address for RF communication;
• said first and second devices exchanging said first and second addresses with each other via said IR interface circuitry such that said first device will recognize said second device as its RF communication partner and said second device will recognize said first device as its RF communication partner;
• and
• said first and second devices being operative to communicate via said RF transceiver circuitry.

A device capable of establishing RF communication with a paired device of a communication pair, said device comprising:

• IR interface circuitry;
• RF transceiver circuitry;
• control circuitry having associated memory for storing a partner address of a current RF communication partner;
• said control circuitry operative to receive said partner address via said IR interface circuitry in an IR communication mode;
• and
• said control circuitry utilizing said partner address to communicate with said paired device in an RF communication mode.
