3.3 Programming and ReadingMARCoThe MARCo transmitter 68320 can be programmed with the Intellibox, on the programmingtrack in. The MARCo transmitter stores its information exactly like a DCC locomotive decoderin CVs and/or registers as in the following table:CVsLocoCVsMARCO MeaningValueRangeFactorydefault1 116 Short address 0-127 317 117 Long address High byte 192-231 19918 228 Long address Low byte 0-255 20829 129 0=Short address valid, 32=Long address valid 0-32 0Programming of long Addresses without Programming MenuIf the MARCo transmitter is not installed in a locomotive with digital decoder (e.g. in a Wagon),then the long address can not be programmed from the Intellibox Programming. CVs 117 and118 must be calculated and individually programmed.Here is a guide for programming address 2000.• Divide the address value by 256 (2000:256 = 7 remainder 208).• Take the whole number result (7) and add 192.• Enter the result (199) as the value in CV 117 (Factory default).• Enter the remainder (208) as the value in CV 118 (Factory default).• Important: Set CV 129 to 32, so that the decoder uses the long address.TIP: If you do not wish to calculate the values for CVs 117 and 118, then if you have alocomotive with the same address, you can read the values of CVs 17 and 18 in thelocomotive decoder and program them into CVs 117 and 118 of the MARCo transmitter.Important: Set CV 129 to 32, so that the decoder uses the long address.It is also possible to program the the decoder using mainline programming from a digitalcenter while it is driving around. The precise method is carried out according to the manual forthe center.If the MARCo transmitter is installed it is programmed, together with the locomotive, using theCV programming according to the column “Locomotive CVs”.The MARCo transmitter can also be programmed separately from the locomotive, when theCVs are programmed according to the column “CVs MARCo”.ATTENTION: There are some locomotive decoders that also use the CVs from the “CVsMARCo” column but for a totally different purpose. In this case the MARCo transmitter canonly be programmed separately from the locomotive.The MARCo transmitter CVs can also be read with the Intellibox (see Intellibox Handbook). If itis installed in a locomotive with a decoder it is always read together with that decoder. Thiscan lead to error reports especially if the locomotive decoder and MARCo transmitter havedifferent values in the CVs. In this case the locomotive decoder must be disconnected fromthe power pickup, i.e. remove the decoder’s plug from its socket. Reading of the values from aMARCo transmitter is similarly possible.NOTE: For programming the decoder, the vehicle must always be on the Intelliboxprogramming track alone. If a number of vehicles are on the programming track then alllocomotive decoders and MARCo transmitters are programmed the same!11
