If your Guide Port RJ-12 cable is not long enough, use this extension cable for
an extra 5 metres worth of length. In order to join two RJ-12 cables
together you will need the Guide Port Cable Coupler.
Warning About Cables
The use of improperly wired cables with mounts can result in damage
to the electronics in the mount, as well as damage to the interface adapter.
The importance of using a properly wired cable cannot be stressed enough. If
you choose to make or buy your own from another source, please be sure it is
built per the description in the user manual.
