A.2.3 SMART-MR10 Connector and Cable Requirements
Custom cables for installing your SMART-MR10 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 (value TBD) fast blow fuse
• Serial data signals (TxD, RxD, signal ground) must be run in shielded cable. Connect shields to
ground at SMART-MR10 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
WARNING!: Failure to observe the given cable construction guidelines in this section
will result in damage to the wiring (not covered by warranty).
