The PLX DM-5 AFR is a standard size 2 1/16" (52mm) LED automotive display designed to display the values measured from the SM-AFR. Measuring only 0.7" (18mm) thin, it can virtually be mounted anywhere. The DM-5 is designed to fit into most aftermarket 2 1/16" (52mm) cups, and mounts for seamless integration into your vehicle. This is an ideal accessory for your SM-AFR module. Up to 32 can be daisy chained together in the iMFD system. There are two recommended uses for the DM-5. The simple setup connects to just one SM module. This is great for stand alone gauges. The full setup is great for monitoring several SM modules simultaneously. The DM-5 automatically "knows" where to look for the information with respect to where it is connected in the iMFD chain.
