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
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
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
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.
