Multiplex Engineering is a technology company specializing in the serial databus standards being used in the automotive industry. We design and manufacture diagnostic interface hardware needed to build OBDII scan tools.
Our diagnostic interfaces support SAE-J1850 VPW, SAE-J1850 PWM, ISO-9141-2, ISO-14230 and ISO-14230. We have shipped over 200,000 diagnostic interfaces since 1996.
We do not sell any software to go with the interfaces. Any interface that you buy directly from Multiplex Engineering will not work with any existing commercial software you purchase from any source. It is necessary that you have, or write, your own.
