The FLGS-TDP XM1000 system is a complete CR1000 based logger system for 32 TDP probes. The CR1000 is housed in a weather-resistant enclosure while collecting data under extremely harsh conditions. The AM16/32 Relay Multiplexer increases the number of sensors that may be scanned by the CR1000 data logger.

The PC400 data logger support software for windows facilitates programming, communication, and reliable exchange of data between a PC and a CR1000 data logger. The interactive toolbar launches and controls independent windows used to communicate with the data logger, edit programs, view and graph real-time data, retrieve stored data, and process data files. The minimum requirements include: Windows, 15MB disk space, VGA monitor, RS-232 port(s) for modem or serial communication interfaces.
