Frequently Asked Questions about our J1962 OBDII connectors: Q.) I am an experimenter / hobbyist, can I buy a small quantity for my own needs? A.) Yes. Please visit our "generic" connector page, and scroll to the bottom to see the link for on-line ordering. Q.) Can you customize the connector to meet my needs? A.) Yes, as you will read below there a number of ways we can customize. As with most custom orders, NRE's and order minimums may apply. Q.) Can you imprint my company name on the unit? A.) Yes, we can easily add your graphics to any portion of the assembly. Q.) Can you color match the OBDII cable assembly to my product? A.) Yes, in most circumstances, an exact color match can be made. Q.) If our scan tool requires only four of the 16 available OBDII positions, can you custom configure the pin allocation and assignment to meet my specific needs. A.) The connector is user customizable. At the time of assembly, you select the pin quantity and pin assignment. Q.) What is the ESD terminal pin back-plane? A.) It is the printed circuit board that the terminal pins are fixed to. The ESD protection comes from a copper ground plane designed to arrest incoming ESD (electrostatic discharge) thereby protecting both the vehicle and the scan tool from high voltage discharges (i.e. static spark). Q. What will fit inside the rear back-housing? A.) Besides concealing and securing the wires and terminals, it will house a PCB large enough for a 32 pin CPU and numerous SMT components. Q.) What purpose would a PCB inside the back-housing serve? A.) The PCB area inside the rear housing allows the designer to discreetly integrate a protocol conversion circuit, or signal conversion circuit into the OBDII cable, thereby eliminating the cumbersome, dangling box usually located in the middle of the cable. This will be especially attractive to PC and Palm based tool companies. There are a number of important design considerations. Please contact us for important details. Q.) What do you mean by Protocol or Signal conversion? A.) Cars speak their own language and computers/palms speak their own language - these are loosely called protocols. To have the computer talk to the car you must translate by converting the protocol. Additionally, some applications may require different signal levels, i.e. instead of 0-5 volts it could be -12 to +12 a design engineer may want to put a signal converter inside the rear housing. Q.) Does Peake Research offer a standard protocol converter PCB for use in their own OBDII connector? A.) Not at this time, but we are interested in moving in that general direction. If you have engineered a software / hardware protocol converter and would be interested in licensing your design to us please contact us. We are in a good position to sell many of them. Q.) What is the cable diameter range? A.) On custom applications we can go as small as 3.5mm, up to 6mm in standard cable sizes. For our off-the-shelf line we currently offer a single size of 5mm. Q.) What vehicles will the Peake Research OBDII connectors fit? Does it fit all cars with the J1962 connector? A.) Virtually all cars produced for North American markets from 1996 on share a common connector known as the J 1962 OBDII connector. The Peake Research "DCX" J-1962 compatible connector, while not adhering strictly to the J1962 specification (due to a few small improvements) was designed to plug into any J1962 equipped vehicle. We have not received a single complaint of incompatibility. Q.) Can you custom terminate my cable at the palm or PC end. A.) This varies depending on the application and quantity ordered. When quantities reach 5k we can do anything. Under that, we will need to discuss the specifics in order to give an answer. Generally, the ideal solution is to adapt abundant, low-cost, off-the-shelf computer cabling to your application.
