DNO and Sound Cards
When using DNO with a sound card you will need to give the sound card a signal that relates to the speed of the model. There are a number of ways to do this described Read More
DNO Current Limit Adjustment
As standard the DNO-5 and DNO-10 have their current limited to approx 50A and 100A respectively. These values are controlled by the value of the DNO current limit adjustment resistor R25 in the diagram below, Read More
DNO Under Voltage Protection
Although the DNO does not have an under voltage protection cut-off fitted as standard it is easy to retro-fit this feature. There are two ways to do this; Method 1; the easiest, is to cut Read More
DNO Version history
The DNO PCB number is 30-2D-01. The following is a list of modifications listed by serial number. The DNO was originally designed to block transition from ahead to reverse without reducing the throttle to zero. Read More
Disabling regen braking [DNO]
Although the DNO is very similar to the VTX, one feature that it does not have is the provision for disabling regen braking via on-board links. A number of people have asked if it is Read More
Double Heading Wiring Diagram [DNO]
This diagram shows how to connect two DNOs in different model locomotives together using the expansion port. You can download a PDF version here. For the slave cable we recommend using a bulgin Read More
Driving the DNO by Raspberry Pi
Our DNO range is ideally suited for use as an interface between a Raspberry Pi, Arduino etc, and a motor. The Pi can provide a PWM output via its GPIO pins and this can be Read More
Positional Servo Control [DNO / VTX]
Notes on how to create a positional servo control. There are two types of servo system: speed and position. These are explained in our Answers to FAQs on Battery Motors & Controllers. There is also Read More
Wiring for Hand Control and Radio Control
We are sometimes asked “Can a switch be fitted to swap between standard hand control and radio control?” This page explains how. The page details the DNO / VTX and Pro-120 but the same system Read More
Wiring for Push Button Use
This diagram shows how to connect a Pro or DNO (or earlier NTX and NCC) series controller for push button use, or with a centre-off switch. Note that the diode shown between the buttons must Read More
