hardware are the PC COM port, the CR1000 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. 77, p. 399).
