1 - Newer dataloggers supply power to the RF401 radio on this connector. Dataloggers purchased before December 1997 require the #14291 Field Power Cable.

2 - The push button that allows you to check/edit programmable settings while the radio is connected to a computer may not operate at temperatures colder than -25°C.
