his cable has one J1939 9-pin male receptacles and one J1939 9-pin female connector.There is also an Molex male connector
 The function is similar to that of Y cables, but the pass-through design can help save some space when connecting and installing telematics or fleet management devices such as ELDs (Electronic Logging Devices).

SAE standards documents on OBD-II

• J1708 - Defines a standard used for serial communications between ECUs on a heavy duty vehicle and also between a computer and the vehicle.
• J1850 - Defines a serial data protocol. There are two variants- 10.4 kbit/s (single wire, VPW) and 41.6 kbit/s (two wire, PWM). Mainly used by US manufacturers, also known as PCI (Chrysler, 10.4 kbit/s), Class 2 (GM, 10.4 kbit/s), and SCP (Ford, 41.6 kbit/s)
• J1939 - Defines a data protocol for heavy duty commercial vehicles
• J1962 - Defines the physical connector used for the OBD-II interface.
• J1978 - Defines minimal operating standards for OBD-II scan tools
• J1979 - Defines standards for diagnostic test modes
• J2012 - Defines standards trouble codes and definitions.
• J2178-1 - Defines standards for network message header formats and physical address assignments
• J2178-2 - Gives data parameter definitions
• J2178-3 - Defines standards for network message frame IDs for single byte headers
• J2178-4 - Defines standards for network messages with three byte headers*
• J2284-3 - Defines 500 kbit/s CAN Physical and Data link layer
• J2411 - Describes the GMLAN (single-wire CAN) protocol, used in newer GM vehicles. Often accessible on the OBD connector as PIN 1 on newer GM vehicles.

  DEUTSCH HD10 series connector 

  The HD series is an environmentally silicone rubber sealed, thermoplastic cylindrical connector, which is designed to be a faster, easier, trouble free assembly diagnostic connector in heavy-duty industry like truck, bus, cross-country vehicle,crane and forklift etc. When mated, the contacts are protected from water, dust, lubricating oils, fuel, road salt, grease, mud and other contaminants encountered.

• Operating at temperatures -40ºC to +125ºC, no Cracking, Chipping or leaking after 20 test cycles from -40ºC~+125ºC.

• No unlocking or unmating and exhibits no mechanical or physical damage after sinusoidal vibration levels of 20 G's at 10 to 2000Hz in each of the three mulually perpendicular planes for 2 hours. Force testing report as below shows

• IP68 rating, waterproof withstand immersion under 1.2 meter of water for 24 hours.
