This updated version remains just as easy to use, but is now completely programmable, allowing even more control, and of course possibilities. As before, the user need only issue the desired commands - the data formatting, error checking, bus arbitration, etc. is all handled by the ELM320.
If you presently use one of our v1. x ICs, you will be pleased to know that this version is pin-compatible with the old (the only difference at power-up is that linefeeds are now on by default) . Simply unplug the old and plug in the new.
