addrelay.tmb
Shows how to use multiple RC51
boards in an expanded system
when more than eight relays
are needed. The receive signals
of all boards are connected to
the host computer transmit
signal, and are given unique
addresses by different numbers
on line 1 of this program.

Program does the following-
- waits for an address value to
be entered followed by carriage
return.
- waits for a relay value for
the RELAYS instruction followed
by a carriage return.
- sets relay if address matches.
