Section 13. Telecommunications and
Data Retrieval
Telecommunications, in the context of CR1000 operation, is the movement of
information between the CR1000 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 CR1000 is with PC200W software by way of a PC COM port. In this
example, hardware are the PC COM port, the CR1000 RS-232 port, and a
serial cable. The carrier signal is PC 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, which utilize two or more
hardware and signal carriers.
Contact a Campbell Scientific applications engineer for assistance in
configuring any telecommunications system.
