The information can be programs, data, files, or control commands. Telecommunications systems require three principal components: hardware, carrier signal, and protocol. For example, a common way to communicate with the CR800 is with PC200W software by way of a PC COM port. In this example, hardware are the PC COM port, the CR800 RS-232 port, and a serial cable. The carrier signal is RS-232, and the protocol is PakBus®. Of these three, a user most often must come to terms with only the hardware, since the carrier signal and protocol are transparent in most applications. Systems usually require a single type of hardware and carrier signal. Some applications, however, require hybrid systems that utilize two or more hardware and signal carriers. Contact a Campbell Scientific applications engineer for assistance in configuring any telecommunications system. Synopses of software to support the various telecommunications devices and protocols are found in Support Software (p. 76, p. 382). Of special note is Network Planner, a LoggerNet client designed to simplify the configuration of PakBus telecommunications networks. 332
