2.1.7 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!
