Using JMRI with NCE Power Cab, SB5 and PH-Power Pro

Posted by on Aug 19, 2015 in Tech Specs, Tips DCC Components, Tips DCC Systems, Tony's Tips |

JMRI works very well with NCE (Power Cab, SB3/5 and Power Pro). The NCE USB is the ONLY way to connect a Power Cab or SB3/5 to a computer. DO NOT USE AN NCE USB TO CONNECT TO A POWER PRO. It will not do what you want JMRI to do. Use a USB to Serial cable to connect your computer to the Power Pro Learn more here Make sure you always use the latest version of JMRI. Download and install SiLabs CP210x drivers for the NCE USB from <http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx> There has been some confusing documentation about jumper settings for a V7 NCE USB. The following are the CORRECT settings for JMRI with various NCE USB versions and NCE hardware combinations. The correct settings for a Power Cab V1.65 or V1.28 (as shown when the Power Cab starts up) and an NCE USB V6 (or you are not sure of the USB version) are: All USB Jumpers off (or at least 2, 3 & 4. Jumper 1 is ignored). JMRI preferences are: System manufacturer: NCE System connection: NCE USB Serial port: <whatever is appropriate for your system> USB version: V6.x.x System: Power Cab Additional Connection Settings->Baud rate: 9600. The JMRI console log should then report V6.3.0. If it reports V7.3.0 and your Power Cab is V1.65, use the settings below instead. The correct settings for a Power Cab V1.65 and an NCE USB V7 are: All USB Jumpers on (or at least 2, 3 & 4. Jumper 1 is ignored). JMRI preferences are: System manufacturer: NCE System connection: NCE USB Serial port: <whatever is appropriate for your system> USB version: V7.x.x System: Power Cab Additional Connection Settings->Baud rate: 19200. The JMRI console log should then report V7.3.7. The correct settings for an SB5 and an NCE USB V7 are: USB Jumper 4 on. All others off (or at least 2 & 3. Jumper 1 is ignored). JMRI preferences are: System manufacturer: NCE System connection: NCE USB Serial port: <whatever is appropriate for your system> USB version: V7.x.x System: SB5 Additional Connection Settings->Baud rate: 19200. The JMRI console log should then report V7.3.1. If this does not work, either: use Help->System console…->Copy to clipboard and paste into a post https://groups.yahoo.com/neo/groups/NCE-DCC/info use Help->Upload Debugging Info… and tell https://groups.yahoo.com/neo/groups/NCE-DCC/info . The JMRI developers on the NCE Yahoo! group can then look in the reports. Your computer will need an Internet connection to do this.

Clearing The Lenz LZV100 Stack

Posted by on Aug 11, 2015 in Tech Specs, Tips DCC Components, Tony's Tips |

You clear the stack of the LZV100 by setting the address on your display to 000 in the same way as you would for any other decoder address. Then, you press the 4 key about 20-28 times. Somewhere, around key press 17-20, you will see a short delay of response on the LH display.  If you have an RRampmeter, you will notice the power to track and the display go off for for a second or two. Shut off power to the system and count to 45. Then turn the system back on.  You will have cleared the stack and reset the command part of it system to factory default. Any decoder address you control with an LH unit will automatically be entered into the system...

Program the PSX delay for Digitrax

Posted by on Aug 7, 2015 in Tech Specs, Tips DCC Components |

  Make sure the programming jumper is on J3, and the normal position is connecting J3-2 to J3-3. To place the PSX in the program mode, move the J3 jumper so that it is connecting J3-1 and J3-2. When you turn the PSX on, it will now flash the software version code. Leave the jumper installed J7-3 to J7-4. This sets the PSX to work optimally with Digitrax systems. Programming: You do not need to give the PSX an address in order to program it. To program CVs, you use Program on the Main mode. This mode wants an address because of the way the POM format works. So when the system asks for an address while programming, you can use any address not on the layout. 9900 is usually a safe choice. Turn on your system and turn on track power. Press LOCO and use the left hand knob to select 9900 (or any other address you like). Hit ENTER. Move the J3 jumper to connect J3-1 to J3-2. Now connect the PSX to the booster output (or clip lead it to the track, etc.). Press PROG until you see in the bottom center of the display Po (You may see P6, Ph, Pd). Now turn the left knob until you see 055=???. Turn the right knob until you see 055=001. Press ENTER. You should see D6 flash. Disconnect the PSX from the booster and move the J3 jumper to connect J3-2 to J3-3. CV55 is now set to 1 and there should be enough delay that moving the engine off/on the track does not trip the breaker. If you want to set CV65, follow the same procedure, except the display would be 065=??? where you use the right knob to set ??? to the value you want (default is 24, so it should be greater than 24). When you are all done, press EXIT to return the system to normal operation. These instructions assume you are using a DT400 throttle.  ...

Block Watcher and Turntables

Posted by on Aug 7, 2015 in Tech Specs, Tips DCC Components, Tony's Tips |

Hi guys. I have a Walthers digital turntable. I also have a digital sound unit with turntable sounds that I operate with a push button. What I want to do is have the sound unit operate when the turntable is activated. The turntable is self contained and I have no desire to tamper with it. So, I would like to cut a current detector with a built in on off switch into the turntable power leads (it runs off a power pack) so that when the detector senses the turntable operating it will turn on the sound unit, thus replacing the push button. Do you have a device that will do the job?    Carl S. Hi Carl, The DCC Specialties Block Watcher will do exactly what you want. It will detect current and turn a switch on. The switch is completely isolated and will switch AC, DC, or DCC and is good for up to 30 volts and 1 ampere. You can also calibrate the trip current level so it only responds to the actual movement of the...

DCC Specialties PSX Circuit Breaker and Digitrax AR1 Compatibility

Posted by on Aug 3, 2015 in Tech Specs, Tips DCC Components, Tony's Tips |

The Digitrax AR-1s are very slow because they are a mechanical relay, and hence keep the reverse short on the layout for an electrically long time. The PSX is fast, so it trips first. The best solution is to switch the AR-1s to PSX-ARs. Since the PSX-AR is a breaker AND a reverser, you can run it directly from the booster and still have short circuit protection AND reversing capability. The next possible solution is institute a delay in the PSX trip time. Set CV55 to 1; CV55 tells the PSX to initiate a delay before tripping. Remember that this will prolong the short on the layout. Try setting CV65 to 160. CV65 tells the PSX how long to delay in 1/8 ms increments. A value of 160 will delay the PSX by 20 ms, which is most likely to work. You can set CV65 as high as 255, but the ideal value is the smallest number that consistently allows the AR-1s to work without interference. NOTE: If you are using the PSX with a Digitrax system, we recommend that you install a jumper from J7-3 to J7-4. This allows the PSX to work with the known properties of the Digitrax booster to help it start the maximum number of sound...

PSX-AR Snap Coil Wiring & Switching Polarity Automatically

Posted by on Jul 16, 2015 in Tech Specs, Tips DCC Components, Tony's Tips |

Hi Guy’s, I’m looking into purchasing 2 PSX-ARSC units but have some questions? 1) I am using Hornby 3 wire point motors (switch motors). On the circuit board you show two common terminals. Do I wire the Hornby common wire to either one of the common ports or do I need to add a jumper across both common ports? 2) I want to use the units on a reversing loop. After the train enters and travels sufficiently round the loop so that the current and the point motor switch what happens next? More precisely, after train leaves the reversing loop what happens? A) Does the polarity and points stay as they are until the next train enters (and goes round in the opposite direction) and then the current and points switch back; or, B) Does the polarity and points revert back to the start position / polarity, and if so what triggers the switch back? C) Either option above is fine – I just want to make sure that I don’t end up in a situation where the polarity of the track reverts back but the points (switch) doesn’t. Thank you Kevin Jones Buy PSX-AR Here Hi Kevin, On the PSX-ARSC the J9-2 and J9-4 pins are wired together and are the coil common. You can connect the common wire from your coils to either one (two are provided since some coils require 4 connections). J9-1 and J9-3 then control the remaining connection to each coil. After the train leaves the loop, the points and polarity remain in the position they were in when the train exited the loop. The track polarity and point position are linked together in software, so they remain locked together. You can manually change the point position/polarity by sending an accessory on or off command to the switch address on the PSX-AR. The default address is 2044. Since the PSX outputs are locked together, you must make sure the point position and track polarity match (for a given point position, the first part of the reverse loop encountered should be in phase). If they don’t, simply reverse the leads to your switch machine....
