Connecting the N8042 & N8042A Rotating Beacon Simulator
Installing the N8042 is very straightforward. Its tiny size and thin construction will allow it to be placed easily in even the smallest scale models. Because the module has circuitry on both sides, care must be taken to be sure that the components or wires soldered will not make contact with any metal object causing a short circuit.
The N8042 can be powered by battery or any well-filtered and regulated DC power source with an output of 6-18VDC.
Included with the module are two 6” lengths of #32 insulated wire. If necessary, these can be used for power input wires.
Most wired decoders have a blue wire which is the common connection for all wired functions (F0, F1, etc.). It is the + DC connection and will be connected to solder point #1 as shown in Fig. 1.
Solder point #1 is the + DC power connection as shown in Fig. 1.
Important note: A low-wattage iron with a pointed tip should be used for connection of wires. Too much heat or solder can easily damage the wires, decoder or module and void the warranty.
Also, all connecting wires should be pre-tinned before soldering them to the module. This will make connection quick and easy and ensure excessive heat is not applied to the solder points.
When connecting the LEDs, proper polarity must be observed. LEDs are “polarity sensitive” and will not function if connected backwards. The N8042 is configured to allow the connection of three (3) 20ma yellow LEDs with device voltages of 2.0 VDC. This covers Ngineering’s Micro and Nano yellow LEDs, as well as many yellow LEDs available. The N8042A Simulator is configured to connect three (3) 20 ma LEDs with device voltages of 2.8-3.3 VDC. This covers all of Ngineering’s 2x3, Micro, and Nano white & blue LEDs, as well as many white & blue LEDs available.
This module will connect to 3 LEDs pre-wired and configured as described in detail in LED Construction. See Fig. 2 below for a complete overview of wiring.
Once again, be sure to use a low-wattage soldering iron when connecting wires to the module.
Our N40M2 12-watt Iron with either the N408I (iron clad) Needle Tip, or the N408X (bare copper) Needle Tip would be an excellent choice for this operation (or any DCC decoder work).
This completes hookup of our N8042 Rotating Beacon module. We hope the added realism it provides enhances your enjoyment of the hobby.
