| 1. A method of conducting communications between a master transceiver and one of a plurality of destination slave transceivers
using a digital communication link comprising the steps of:
(a) at said master transceiver, transmitting toward a destination slave transceiver an information packet having a slave transceiver
address field and a slave transceiver identification field, said slave transceiver address field containing a slave transceiver
address code representative of the physical location of said destination slave transceiver relative to the physical location
of said master transceiver, and said slave transceiver identification field containing a slave transceiver identification
code representative of a logical address of said destination slave transceiver;
(b) at a respective slave transceiver between said master transceiver and said destination slave transceiver, receiving said
information packet, modifying the value of said slave transceiver address field of said information packet to produce a modified
information packet, and transmitting said modified information packet toward said destination slave transceiver; and
(c) at said destination slave transceiver, capturing said modified information packet, in response to contents of the the
slave transceiver identification field of said modified packet matching a slave transceiver identification code representative
of a logical address of said destination slave transceiver, or in response to said slave transceiver address field of said
information packet having a prescribed value.
