2.1.4 Battery Backup
A lithium battery backs up the CR200(X) clock, program, and memory if it
loses power.
2.1.5 Power Supply
The CR200(X) is powered by a nominal 12 volt DC source. Acceptable power
range is 7 to 16 VDC.
The CR200(X) does not have an internal power supply but does have
connections for an external battery and a built-in charging regulator for charging
a 12 V lead-acid battery from an external power source. Charging power can
come from a 16-22 VDC input such as a solar panel.
2.1.6 Antenna
For CR200(X) models with a built-in radio, an FCC authorized antenna is a
required component. An SMA male connector is provided on the CR200(X)
wiring panel for antenna connection. Antennas are either 900 MHz or 2.4 GHz
depending on the type of radio installed.
