On-site serial communications are preferred if the datalogger is near the PC,
and the PC can dedicate a serial (COM) port for the datalogger. On-site
methods such as direct serial connection or infrared link are also used when the
user visits a remote site with a laptop or PDA.
In contrast, telecommunications provide remote access and the ability to
discover problems early with minimum data loss. A variety of devices, and
combinations of devices, such as telephone modems, radios, satellite
transceivers, and TCP/IP network modems are available for the most
demanding applications.
2.1.2 CR1000 Mounting
The CR1000 module integrates electronics with a sealed stainless steel
clamshell, making it economical, small, and very rugged.
2.1.3 Wiring Panel
The CR1000 module connects to the wiring panel, which provides terminals
for connecting sensors, power and communications devices. The wiring panel
also incorporates surge protection against phenomena such as lightning. See
FIGURE 2.1-1.
2.1.4 Battery Backup
A lithium battery backs up the CR1000 clock, program, and memory if it loses
power.
2.1.5 Power Supply
The CR1000 can be powered by a nominal 12 volt DC source through the
green “POWER IN” connector. Acceptable power range is 9.6 to 16 VDC.
