65853 Marantec Old-to-New Programming Cable
Old-to-New Programming Cable is used to transfer the code from a
programmed remote to a new remote. Marantec garage door openers are
different from other brands in that they only hold the code for one
remote. Then when you get additional remotes the code from that one
programmed remote is copied on the new remotes by connecting the two
remotes with the programming connector and transferring the code. By
doing it this way you are able to add as many remotes to the operator
that you want.
*The Old-to-New Programming Cable can only be used
on remotes that have the same frequency. If you want to transfer the
code from one remote to another check the frequency printed on the back
of the remotes. If they aren't the same frequency the transfer won't
work. The cable also only works between the old ML style remotes (see
picture below) and the newer "M3" models and Digital remotes.
