RS-232 Computer Interface
The WS-1000 firmware will support the computer interface to upload and download the
eight memory blocks. If you intend to use the computer interface, jumper J7 must be
changed. TTL for the Peet Brothers Weather Station and RS232 for the computer
interface. Solder a single pole double throw toggle switch to the three-conductor
cable provided in the WS-1000 kit. Connect the header plug to J7 and mount the switch
in a convenient location. This will simplify changing between the weather station and
the computer interface when the CAT-1000B is in the rack mount enclosure.
The Davis Weather Wizard III operates through the RS-232 port so the change over
switch is not required.
