Cable, J1962M to DB9F, Type D, 6ft

P/N:	143301
Description:	Cable, J1962M to DB9F, Type D, 6ft
Weight	8oz / 218g
Length:	6ft / 1.8m
AWG:	24
Warning:	The OBD-II cable is designed to be used in conjunction with ElmScan family of interfaces (or other interfaces, which isolate your computer from the vehicles electrical system). Plugging the cable directly into the PC may damage the serial port.

Features: RoHs Compliant Designed with the European market in mind. The thin shell allows the cable to mate with J1962F connectors built into the dashboard. Very good noise immunity: BUS+/BUS-, and CAN High/Low lines are twisted pairs. External shielding (aluminum foil).
