The following guidelines are provided here
for addressing KTX keychain transmitters
and RCR receivers.
The encoders and decoders used in these
products allow for tri-state addressing. That
is, each of the 8 address nodes may be set in
either ground, +Vcc or open states.
As shipped from the factory, the address
nodes for both products are set to ground,
and it is not necessary to modify these
address for the products to work together.
However, if a different address is desired,
address nodes on both transmitter and
receiver must be set to the same
configuration.
The following describes how to set an
address node to a particular state:
Open State
To configure a node in the open state, the
trace connecting the address node to ground
must be cut.
+Vcc State
To configure a node in the +Vcc state, the
trace connecting the address node to ground
must be cut AND a connection must be
made from the address node to the +Vcc
node. A dab of solder is typically used to
short across the solder bridge.
Ground State
As configured from the factory.
