Abstract: HVAC network devices are provided with radio frequency identification tags (RFID tags) which can be read by a read/write device. The read tag identification of each network device is stored in memory within the HVAC network device. A device capable of reading the RFID tags of the HVAC network devices will be used by a person to assign network addresses to each network device. In particular, the person will use information concerning the location of an HVAC network device to determine the network address that is to be assigned to the network device. The thus identified network address along with the tag identification is transmitted to a network controller for the communication network. The network controller will transmit a configuration message over the communication bus that will include the tag identification as well as the desired network address.

Abstract: A digital transmitter (13) for transmitting serial words of predetermined length at selected speeds for output at a plurality of parallel channels (120, 120'). The words selected for series transmission at said parallel output channels (120, 120') are sequentially repeatedly applied to a multiplexer (89) which forwards selected bits from these words at fixed and variably setable speeds to a selected shift register (101 or 102) and latch (105 or 106), combination for output transmission.
