Transparent Data Link on 868/914MHz band

A DWA3 is a single channel, 869 or 915MHz wideband, transparent data link. It has a TDL2A pin out (and firmware), but uses a BiM3 series radio module. DWA3 acts as a transparent serial cable to attached host. DWA3 is an intermediate level OEM radio modem which is in between a raw FM radio module like BiM3A/BiM3B and a sophisticated OEM radio modem like RPM3. It takes care of preamble, synchronisation, bit balancing and error checking along with automatic noise squelching.
