The RLM20 is the retail version of the LM15a
Socket Rocket. It is a lamp module that
screws into the lamp socket. It does not dim
like most; only does on and off. To program
it you turn on the lamps local switch and
then have 30 seconds to send an X10 ON
signal on the address you want it to follow.
Like if you want B4. Turn on the local lamps
switch send a B4 ON; B4 ON; B4 ON. It then
is programed to B4. You can even do it in a
convenient lamp and move it to the place you
want it to be used. It will sat on B4 unless
you send a different address 3 time as it is
powered up. If it is on the DS7000 Security
Lights address it will flash like any other
lamp module would. Also the standard X10
buttons on the remote can also turn it on or
off if the address is correct.
