Data Storage and Retrieval Peripheral Overview
Campbell Scientific offers a full range of communication devices. On-site peripherals include external data storage devices, PDAs, laptop or desktop computers, and displays.
Telemetry peripherals support communications between the datalogger and one or more computers. These peripherals allow the user to access remotely the datalogger's real-time data, stored data, and programming. Examples include short haul, multidrop, telephone, radio, and satellite modems.
Combinations of on-site and telemetry devices can be used in the same application for maximum flexibility, convenience, and reliability.
There are several options:
- Use the SC-USB connector/interface.
- Use the SC32B with a p/n 17394 (USB-to-9-pin RS-232 cable).
- Use a user-supplied USB interface with the SC32B.
If the datalogger being used has an RS-232 port, only a serial cable is needed. It is not necessary to use the SC32B unless there is another device connected to the RS-232 port or there are concerns about low-level noise from a permanently connected, ac-powered computer.
In its simplest form, a server "hears" requests and "delivers" answers. In the case of RTMC Web Server, it "hears" requests from PCs, and it delivers files using hypertext transfer protocol (HTTP), the language of the Internet.
Be ready to provide information about the measurement system, such as datalogger, power supply, and telemetry preferences. Depending on the system, there may be questions about the distance between measurement stations, type of topography, and location of each station. It may also be helpful to provide maps of the measurement area.
