SECTION 1. RTMS SYSTEM OVERVIEW

Real Time Monitoring Software (RTMS) is PC software designed to enhance the capabilities of the CR10T

and future Campbell Scientific dataloggers. RTMS provides data collection, monitoring, and control for

applications involving one or more CR10T dataloggers. RTMS is designed to do several tasks

concurrently. OS/2 was chosen as the operating system. Using OS/2 multitasking, data can be collected,

displayed, analyzed, routed, and archived simultaneously.

The computer running RTMS, dataloggers, and

the various communications interfaces (RF95T,

SC32A, MD9, phone modems, etc.) form a net-

work with a physical communications path to

and from each of the dataloggers. The Data-

Logger Services Manager (DlsMgr) module

manages the network, organizing the exchange

of information between the computer and the

dataloggers. This information can be data-

logger data, control information, datalogger

programs, etc. DlsMgr handles multiple data

requests from multiple CR10T sites simulta-

neously within the network. Since the most

common request is for datalogger data, this

communication is optimized so that datalogger

table data can be retrieved quickly in an

ongoing method. DlsMgr in turn makes the

datalogger data available to other applications

such as DBSelect and RTM.
