SMART6 Connector and Cable Requirements
Custom cables for installing the SMART6 can be created using the following guidelines:
•
Wire size: must be 0.5 mm-1.25 mm (20-16 AWG)
•
Batt+ connection must be protected by 5 A fast blow fuse
•
Serial data signals (TxD, RxD, signal ground) must be run in shielded cable. Connect shields
to ground at SMART6 end only
•
CAN signal conductors must be twisted (40 twists/m, 12 twists/ft)
•
Use only the recommended mating connectors listed below. Use only gold plated pins
The connector used in the SMART6 is an “AMPSEAL” dust and water sealed type produced by Tyco. The
following part numbers pertain to the mating connector required to make connections to the SMART6. These
numbers are provided for information only and are not available from NovAtel as separate parts.
