Re: DR4018 & DC Question

 

Don , Let's start chasing down this buzz. I want you to take out the signal wires and no power going to the DR4018 and turn on track power. if there's no buzzing then It's not the turnout. Next put the signal wires back in so the blue wire is to the right (inside ) and turn on track power If It's still buzzing turn off track power and remove all of the ?but one?DR4101 and remove the common wire, and turn on track power and see if its buzzing still. If still buzzing ,turn off track power and put the common back and take of one of the blue wires. let us Know how that goes. It's always a pain in the ass to find a grounding problem ( The buzzing )

My thoughts are:

1. Add the RRAmpmeter to the test bed and see what is happening, if that works then:
2. Check the DR5000 that it is set for 3000ma. and not 1500ma.
3. Check that you have not accidentally reversed a buss wire drops to your track, meter and check you did not reverse a drop.
4. I watched a video of someone who uses the Kato Turnouts and he isolates both rails on the threw and diverging routes.

Re: DR4088 LN CS wiring, twisted or not, ? help a confused newbee! but do i keep them parallel?

 

LocoNet is not RS-485. RS-485 is a master/slave polled serial bus, whereas LocoNet is a peer to peer CSMA/CD network much like Ethernet, just running way slower so that it works over flat cabling and various topologies. NCE cab bus, Lenz XPressNET, and C/MRI use various implementations of RS-485, with NCE running at 9600 baud, and XPressNet running at 62.5kbps. Those numbers can be compared to each other, but not to LocoNet's?~17kbps bandwidth, as LocoNet is far more efficient in using that bandwidth due to CSMA/CD not having the polling overhead.

LocoNet is not designed to be run on twisted pair wiring, but I don't fully understand why. NCE is now encouraging the use of twisted pair CAT-5e cables with their new throttle panels, but I think that's more about carrying more DC power for throttles than anything to do with their RS-485 bus signal.

However the DR4088 (or at least mine does - DR4088LN) uses current sensing to detect presence or otherwise of a loco or resistor wheelset and at that frequency, the tail wiring shouldn't need to be twisted tough it shouldn't do any harm if it is.

The Loconet bus will be a balanced signal bus which, I believe it uses EIA RS-485 signalling between the 4088 and Command Station and therefore should be a twisted pair for noise rejection, especially if the signal run is a significant length. It should not need to be shielded but in the electrically noisy model railway environment that should be considered. The idea of a balanced signal is intended that induced noise will be cancelled out and thus longer cable runs are possible. RS-485 is a relatively low speed bus compared with CAN-bus and ethernet UTP (TIA-568) though these busses work in noisy environments too.

Enough waffle! I wouldn't worry about twisted pairs on the track to DR4088 wiring - mine is a real rat's nest but it works. On the DR4088 to command station cables use good quality pre-made RJ-12 'phone cables which should have twisted signal pairs (I don't remember the TIA spec number). I have 50cm, 1m, 3m and 5m in use without issues.

Re: DR5000 Network Interfaces.

 

Ian

Around the beginning of 2019 we inquired to find out if the DR5000 WiFi and LAN could use different protocols and were told no.? This was for our test environment when we were evaluating the DR5000 for use on our club layout.? As far as I know this has not changed.? It may be an underlying hardware limitation - the Raspberry PI has a similar limitation.

What software does the user want to use to control his layout?? ?If we knew more specifics there might be a way to accomplish what the user wants to do


Re: DR4018 & DC Question

 

Dennis,
? ? ? ? ? ? ?Yes, I have done that. I completely disconnected the DR5000 from the layout and ran the track output wires of the DR5000 straight to the DR4018 signal inputs. I then connected a Kato turnout using a DR4101 to the DR4018. I then connected a 12v 3a wall wart power supply to the power inputs on the DR4018. When track power was turned on there was no buzzing noise from the turnout. I also tried the exact same setup except with the DR5000 connected to a laptop via USB. I ran the DR5000 software so I could throw the turnout and it worked as it should.

Hi James,

That would work and I think is the way I've currently got the last 4018 setup (ie. all preset 6 for my MTB's)? ?So I was hoping to add the relevant CV's to switch the last three outputs to lights for ports 11 - 16.

Many thanks,

Hello Suart
Would be alot easier?to do this the other way round the first out put?for the motors CV47 to a value?to 6.

The other output?for the light would this be ok?
If so I will send across?the CV to change.

Re: DR5000 Network Interfaces

 

I use Rocrail on a RaspberryPi connected to my DR5000 using Loconet over LAN. I do not use the WiFi at all. I have a Roco Multimouse connected directly to the DR5000 using the XN+FB port. So the network is not the same as propsed. However, the Multimouse does control Locos and DCC connected accessory decoders while the LAN is active and (different) devices controlled by Rocrail. I wouldn't be surprised if manual operation with the multimouse would confuse? Rocrail however! I must say the multimouse is most useful for testing devices even though I have to remember to increase the accessory addresses by 1.
