Section 13. Telecommunications and<br />
Data Retrieval<br />
Telecommunications, in the context of <strong>CR200</strong>(X) operation, is the movement of<br />
information between the <strong>CR200</strong>(X) and another computing device, usually a<br />
PC. The information can be programs, data, files, or control commands.<br />
Telecommunications systems require three principal components: hardware,<br />
carrier signal, and protocol. For example, a common way to communicate with<br />
the <strong>CR200</strong>(X) is with PC200W software by way of a PC COM port. In this<br />
example, hardware are the PC COM port, the <strong>CR200</strong>(X) RS-232 port, and a<br />
serial cable. The carrier signal is RS-232, and the protocol is PakBus®. Of these<br />
three, a user most often must come to terms with only the hardware, since the<br />
carrier signal and protocol are transparent in most applications.<br />
Systems usually require a single type of hardware and carrier signal. Some<br />
applications, however, require hybrid systems, which utilize two or more<br />
hardware and signal carriers.<br />
Contact a <strong>Campbell</strong> <strong>Scientific</strong> applications engineer for assistance in<br />
configuring any telecommunications system.<br />
Synopses of software to support the various telecommunications devices and<br />
protocols are found in Section Support Software (p. 143).<br />
13.1 Hardware and Carrier Signal<br />
<strong>Campbell</strong> <strong>Scientific</strong> supplies or recommends a wide range of<br />
telecommunications hardware. TABLE. <strong>CR200</strong>(X) Telecommunications Options<br />
(p. 131) lists telecommunications destination, device, path, and carrier options<br />
which imply certain types of hardware for use with the <strong>CR200</strong>(X) datalogger.<br />
Information in TABLE. <strong>CR200</strong>(X) Telecommunications Options (p. 131) is<br />
conceptual. For specific model numbers and specifications, contact a <strong>Campbell</strong><br />
<strong>Scientific</strong> applications engineer or go to www.campbellsci.com.<br />
