Oct 26, 2024 · CV 29 before programming = 006 = 0x06 = 0000 0110 b - bit 2 is set so analogue (DC) available Programed loco to 411 as it was a 411 CV 29 after programming = 034 = 0x22 = 0010 0010 b = bit 2 is clear so DCC only, extended address range as address is greater than short address so bit 5 set, bit 1 is unchanged Jan 13, 2012 · The look up table below shows the results of different CV values that you can program into CV29. DCC CV29 Calculator. CV 28 bit 2 must be set. Please note: Some CVs (such as CV29) have specific meanings for each bit. Our CV 29 Calculator can automatically generate the value needed by simply selecting your desired options! Bit 3 is ignored by the DCC system firmware. If done correctly, there is no risk whatever to other locos or accessories on and about the layout, because you dial up the loco first, so are only addressing it, not the layout as a whole. com The DH165 series has "analog mode conversion"; the default setting is for operation in both DC and DCC environments. Oct 26, 2024 · So what is DC runaway, it is the loco shooting off because is sees the DCC signal as DC and so runs at the rectified value of the DCC voltage. CV values are shown in both decimal & hex. (Typical values are CV 28=3 or CV 28=131) If you’re unsure, you can place the locomotive on the Programming Track to read the value of CV 28. If you use an extended (4-digit) decoder address of 128 or higher, activate the speed curve by setting CV 29 = 62. )A 2 digit decoder address can extended address will only be recognized by the decoder when CV 29, bit 5 is set to 1. The locomotive must be…. Keep in mind that CV 29 is a Bitwise CV, and failure to properly modify the CV can result in other features being inadvertently modified. Seen it happen and sure enough it shoots off. (See your DS54 manual for special method of programming CVs related to stationary decoders that are above this range. The speed curve is then controlled by CV 68-93 (speed steps 2-27). A TCS UWT will show you which bits are set. CV 29 Program the sum of the value(s) you choose into CV 29 CV 29 Configuration: CV 29 is the primary configuration CV in all DCC decoders and can be used to make basic setting changes. If you do not know the current value of CV 29 you can read CV 29 using the program track. Order Ascending; Order Descending; mike33469. The DT100 is limited to programming CV#s 01-128. Please visit our Video FAQ page In this episode of MRVP's DCC Programming Series host Dana Kawala takes on CV 29, one of the most powerful (and often-feared) configuration variables in DCC. CV 17 contains the most significant byte and must be loaded with values within the range of 0xC0 and 0xE7. I think half the blame must go on the makers of throttles which attempt to be "friendly" but fall a bit short and leave their users stuck without a clue what is going on. It does so with Bit Switches to activate features by setting a specified bit on or off. As I said earlier I'd be annoyed if other settings unrelated to the address were changed by the DCC system. May 10, 2023 · This CV is used to set up or enable basic functions of your decoder such as direction, speed step modes, enable/disable DC operation, and select the active address type. This CV is used to set up or enable basic functions of your decoder such as direction, speed step modes, DC operation, and address type. CV29 is probably one of the most useful, but also one of the most feared, CVs in a DCC locomotive decoder. The bit assignments in this table use a bit numbering scheme of 0-7 to correspond the NMRA convention for universal bit numbering. When this setting is enabled, the decoder will use a 4-digit "long" address. 18 replies. Enable the speed curve by adding a value of 16 to the current value in CV 29. If the decoder does not support a feature contained in this table, it shall not allow the corresponding bit to be set improperly. CV values are shown in both hex & decimal. Dana methodically walks you through how to use CV 29 to control many of the basic functions of your DCC-equipped locomotives, Oct 1, 2017 · Electronics and DCC » CV 29; CV 29 5832 views. Dec 22, 2014 · Courtesy of Digitrax. Decoders don't change other bits by themselves. You can fix it in software but a lot of companies don't implement it. Jul 27, 2013 · But it gets messy when a CV contains many configuration options. Many handhelds use a scheme of 1-8 to refer to Jan 17, 2023 · NMRA CV 28 - Bi-Directional Communication Configuration (RailCom®) This CV is used to configure decoder’s bi-directional communication characteristics when RailCom is enabled in CV 29. CV 18 contains the least significant byte Jun 3, 2024 · RailCom enabled in CV 29 (see below) RailCom- addressed feedback must be enabled in the decoder. Jul 16, 2024 · This setting will disable CV 5 and CV 6 for use in the 3-Point Speed Curve when enabled (CV 2 will always be enabled for use) OFF 16 Address Type This setting switches the Address Type between 2-digit and 4-digit addressing. CV 29 has a default value of 6, so to enable the 4-Digit Address just add a value of 32 and pro-gram the resulting value of 38 into CV 29. CV29 is one of the most advanced CVs defined by the NMRA and is used to configure multiple settings such as speed step modes (14/28/128 speed step modes), DC operation, 4-digit addressing, and more. Let’s review how the manual of the decoder might look like: 0 = Standard orientation; 1 = Reversed orientation … 0 = Respond to short address as defined in CV#1 Mar 30, 2023 · This setting will disable CV 5 and CV 6 for use in the 3-Point Speed Curve when enabled (CV 2 will always be enabled for use) OFF 16 Address Type This setting switches the Address Type between 2-digit and 4-digit addressing. Member since March 2002; 228 posts CV 29 Mar 10, 2021 · Most, but maybe not all, DCC Command Stations can POM (Program On the Main) but you use a different setting from that for the programming track. Decoder Lock is used when a locomotive has 2 or more decoders in it. See full list on dccwiki. If you find that you have a decoder that is acting up, I have found that it can often be fixed by re-writing CV 29 rather than doing a full reset of the decoder. Within the setup of a DCC controlled locomotive, CV29 seems to cause an inordinate amount of trouble. CV29 Values: The factory default value for CV29 is 06. See the table below for more information on the settings controlled by this CV. For instance, if you would like to use 28/128 speed TCS CV 29 Calculator Visit Tool . The columns show the function outputs on your decoder that you can map to be controlled by the function controls on your throttle. Each row shows a function control key on your throttle and its associated control CV. Jul 16, 2024 · NMRA CV 29 - Configuration Data #1. CV Value for CV29 Hex or Dec Speed Steps / Speed Table Analog Mode Conv Normal Direction of Travel 2 or 4 Digit Addr x00. It allows configuration of up to 8 parameters which contribute to the operation of the decoder and can bite if not set correctly. Inside CV29, each bit has a unique meaning. Changing CV 29 (Bit 0, Direction) reverses both the locomotive's direction of travel and its lighting effects. Most command stations have a method of automatically entering a 4-digit "Long" address which will May 21, 2024 · The Normal Direction of Travel is configured with CV 29. CV number 29 is a good example (because the DCC standard defines it so). Consist Addressing is similar to Short Addressing in that it can accept values from 1-128. This is sometimes difficult to determine if you have a decoder where you can't easily read CVs. Here is a listing of the bit meanings: Bit 1 ON [1] = 28 Speed Step Mode (should always be enabled) Bit 3 is Railcom and is usually ignored by the DCC system firmware. Bit 4 ON [1] = Alternate Speed Curve Active OFF [0] = Use table defined by CV 2, 5 and 6. Bit 5 ON [1] = Use long address in CV17/18 OFF [0] = Use short address defined in CV1. CV29 controls a number of features on both Accessory and Multifunction Decoders. In practice, most Digitrax operators now only use decimal. Manufacturers of the highest quality DCC Decoders and Control Systems for Model Railroads Program the above value into CV 29: Train Control Systems. Oct 26, 2024 · Yeah but Colin's saying his observations show other CV 29 bits being changed/cleared by the action of programming an address on his Elite. The look up table below shows the effects of different CV values that you can program into CV29. Bits 6 and 7 are ignored by the DCC system firmware. On a Digitrax system, rather than figuring out what value CV29 should be, simply reprogramming the address will cause the system to also write CV29. To set-up CV 29 select the features from above that you want to use and tally up the corresponding values. There are some that do not want this feature, and it can be disabled by setting CV29. Phone (215 Click here for more information on CV33 - CV46.
