8.4 Telecommunications and Data Retrieval
Telecommunications, in the context of CR800 operation, is the movement of
information between the CR800 and another computing device, usually a PC. 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.

any telecommunications system.

protocols are found in
