First I have received several very generous offers from members of s.e.d
to help me with the programming my remote light switch project and I
greatly appreciate your help. But before I can send off the
requirements I need to resolve a couple of things.
Right now I have it working with two PIC 16F87x processors, one in the
base switch and one in the remote, communicating via Linx 916Mhz
tranceivers. The final system will have 3 remote stations. One at the
navigation station, one in the cockpit and a portable one to carry in
the dinghy. I can see how by sending a station address in the data
stream multiple remotes can exist in the system. The base broadcast the
system status every 30 seconds and the remotes send 4 byte command
strings only when a button is pressed so collisions would be very rare.
The thing is, these tranceiver modules cost $40 each and are not really
needed or desired for the perminently installed remotes at the
navigation station and cockpit. I would like to keep the programming the
same on all stations and just eliminate the tranceiver on the fixed
stations. Can I get by by just routing RX/TX/SDO/SDI to a modular jack
and tying them to the base with CAT5? The wire runs would be about 30'
max.
