EDITs Pro Control Unit Protocol

Without question, the EEDTS Pro protocol has been the subject of most discussions related to EEDTS Pro, due to the fact that it differs from the old EEDTS and the Motorola protocol.Furthermore, many users and software suppliers have found it difficult to convert addresses and date to the trits coding required by the EDTS controller.Consequently, the protocol has been extended to include the command set listed in Table 1.Naturally, the existing command set (as described in the EEDTS Pro book) is still fully supported, and the new control unit is downwards compatible with the old version.The Märklin protocol formed the starting point for this move, but since that protocol does not have any commands for the extra functions, an extra byte has been specifically added (in particular, for the locomotive control commands).
