Wiring Panel – The set of terminals and underlying circuits that enable
connections of sensors, control and power supply wiring to the datalogger
itself. Some dataloggers such as the CR23X have built-in wiring panels.
Others, such as the CR10X, have removable wiring panels.
Watchdog – An entry in the status table that shows the number of watchdog
errors that have occurred. The watchdog checks the processor state and resets it
if necessary. If an error occurs, the watchdog error counter is incremented.
