The jacks on the front and sides of the UP5, UR92, UR91, UR90, and LNRP front panels are Throttle Jacks and should only be used for connecting throttles to LocoNet. They should not be used to connect to other LocoNet devices. The jacks on the back of these units are LocoNet Jacks that are used for connecting LocoNet devices to the network. Technically speaking! These units were designed to have the FRONT jack's second Railsync differential signal run as a diode-or'ed power source (for throttles). This means that some cable orientations and power loads could cause unexpected operations in downstream LocoNet devices ...
1) Does the LNRP terminate and re-time the LocoNet data signal in both directions? Yes 2) Does the LNRP repower the LocoNet data lines for each segment? Yes 3) What happens to the signal on a protected segment when there is a fault on an adjacent segment? Nothing, it keeps going 4) What happens RailSync on a protected segment when there is a fault on an adjacent segment? Nothing, it keeps going 5) What do the various diagnostics/error indicators really do? They monitor and report the protected sides. A Digitrax PS14 power supply is required for correct operation.
LocoNet is Digitrax's method of communication between LocoNet compatible devices on a model railroad layout. LocoNet compatible devices are designed to work together on the network, and in some cases can also accept DCC commands from the track, but often go beyond the scope of simple DCC train control. LocoNet is a peer-to-peer Ethernet type multiple access network. Because of its design architecture, it is very robust and powerful. Layout implementation is simple and wiring is free form with minimal limits. LocoNet is designed to run an unshielded 6 conductor ribbon cable. Digitrax recommends using flat, six-conductor telephone wire ...
Q) You are offering a Loconet Repeater Module LNRP. Is it an RailSync Booster, too? There is no description in the PDF-File about this attribute. A) The LNRP boosts (and separates) the Railsync "Standard" outputs from the master command station ("Protected" Railsync), so if there is a problem with this separated "Standard" Railsync copy, the master Command Station is unaffected along with other devices like track boosters that need good Railsync copies. This boosted Railsync is also over-current protected and the LNRP will turn off an overloaded "Standard" Railsync and automatically retry re-powering, so when the fault clears the "Standard" ...
Installation: Figure 1 shows the general arrangement for connecting one or more LNRP's to configure a LocoNet based system for operation. Note that the LNRP's drive the power and Railsync signals on the "standard" LocoNet cable segments, so each LNRP should have a DC input of +15V to +18V at up to 250mA supplied on the side DC power jack. Note that the shaded cable connections are made from the protected network side connections of the LNRP units to the components that are on the "protected" or high reliability part of the System. The other solid cable connections are the ...
I have purchased an LNRP, UR90, and 4 UP5s. I have noticed the LNRP seems to have a solder point between the two LocoNet jacks as the UR90 and UP5.Can all of these be connected to the same 12 volt power supply? No. It is important that each LNRP has its own power supply. As noted in the documentation that comes with the unit, "the LNRP drives the power and Railsync signals on the standard LocoNet cable segments, so each LNRP should have a DC input of +12V to +18V at up to 250mA supplied on the side DC power ...
