Peet Brothers Weather Station Setup
Connect the weather station component cables as described in the weather station
owner’s manual. Install the 9-volt battery. If you use the rain gage it will be
necessary to set the weather station's clock so the rainfall will clear at midnight.
Davis Weather Wizard III Interconnect
Install the Weather Link in the base of the display unit. Adapt the modular phone
plug to the CAT-1000B J1 connector as described in Figure 12-2. Note: the 25 pin "D"
adapter cannot be connected directly to J1. You must prepare an adapter cable or use
a modular wall jack. Connect the black wire on pin 14, the green wire to pin 4 and
the yellow wire to pin 17 of J1. To test the interface, unlock the CAT-1000B and
enter the [*27] programming command. If the controller and the weather station are
communicating, the voice synthesizer will say: "CONTROL OK." If a problem exists the
voice will say "ERROR NO DATA." This command will also reset the high and low
temperature to the current reading.
