CV29CV29 is the basic decoder setup CV that is used by all DCC decoder manufactures. So,if you are familiar with CV29 from other manufacturer's decoders MTH's is nodifferent. The most important part of CV29 is the ability to switch between long andshort addressing. By default, CV29 on your MTH PS3.0-equipped engine is set to 2.Long and Short AddressingLike most DCC Decoders, your MTH PS3.0-equipped engine can be programmed withboth Long and Short Address. Short addresses are those from 1-127 and Longaddresses are those from 128-9999. You can program the engine address either withProgramming on the Main (PoM) or using a Programming Track. Since it's easiest, inmost cases, to PoM the instructions will show you how to do it this way.By default, your MTH PS3.0-equipped engine comes programmed with both a longand short DCC address. The default Short address is always 3. The default Longaddress will be 3333.To change your engine's Short Address using PoM:1. Call up the engine's current address on your DCC handheld2. Enter Programming on the Main on your DCC handheld3. Enter the new address you want – Remember you can only use address 1-127 forShort Addressing4. Once you hit Enter the engine will give you a two whistle/horn blast response5. Call up the engine on its new address and away you go. Alternatively, dependingupon the type of DCC system you have, you can enter PoM and then write the newaddress in the Address Menu. This only works for short addressing. For example,on an MRC Prodigy Advance2 system, you would:1. Call up the engine's current address on your DCC handheld2. Hit the PROG button twice to enter PoM mode3. Hit Enter twice so the LCD displays “Adr”4. Type in the new Short Address (1-127) that you want and hit Enter5. The engine will give you a two whistle/horn blast responseRailKing Diesel Engine w/Proto-Sound® 3.021SD60
