2.1.8 Data Cable Recommendations
The new design of the Trailblazer replaces proprietary cables with standard
CAT5 Ethernet cables terminated with RJ45 connectors for the sync and
repeater functions.
NOTE: Feed the cable through the weatherproof cord grip before terminating it.
The cord grip is too small to accept an RJ45 connector especially while occupied
by other cables!
