Introduction

SPROG II is a DCC decoder programmer for connection to the USB port of a

personal computer or similar device. SPROG II is supported by DecoderPro

and PanelPro, both part of the JMRI project (http://jmri.sourceforge.net/)

which, by use of the java programming language, allows platform

independent support of a wide range of DCC hardware. The JMRI software

is shareware available as a free download.

SPROG II is also capable of operating a small layout using the features of

DecoderPro and PanelPro. A larger layout can be driven by using an external

booster.

Requirements

 DecoderPro from http://jmri.sourceforge.net/ or the optional USB stick

 Regulated DC Power Supply (see Table 1)

 Short length or small oval of track for programming and/or test running

Features

 Programs virtually all NMRA compliant DCC decoders

 No extra hardware required for programming sound decoders (e.g. QSI,

Soundtraxx)

 Easy to use graphical interface with DecoderPro

 USB interface for easy connection to PC

 USB activity LED shows communication with the PC

 Power LED flashes when programming track power is live

Notes:

1. Minimum supply voltage depends upon the requirements of the

decoder being programmed. In general it is safer to use as low a

voltage as possible in case of problems with a newly installed

decoder.

2. SPROG II will remove track power if output current exceeds 250mA

as measured 100ms after applying power. Surge current during

decoder power-up may be considerably greater than this.

3. Depends upon required DCC current.

4. SPROG II is protected against reverse polarity connection of the

power supply but will not work unless the polarity is correct.

SPROG II is not protected against track and power connections being

interchanged.

SPROG IIv4 User Guide 6

Installation

The following steps are required to install SPROG II before you can use it for

the first time:

 Install the latest production version of JMRI (4.22 at the time of

writing)

 Connect the Power Supply

 Install SPROG II USB drivers (if required, depending on Operating

System)

 Edit DecoderPro preferences

 Connect the Programming Track

This document gives brief installation instructions. Please refer to the

appropriate driver installation document on the optional USB stick or on the

SPROG DCC Ltd website.

For instructions to install the JRE and DecoderPro on Linux, please refer to

the Install Guides on the JMRI website at http://jmri.sourceforge.net/download

Install DecoderPro

DecoderPro should be installed from the optional USB stick or a downloaded

copy. The USB stick includes a recent production version (but not necessarily

the latest). A newer version of DecoderPro may be available from the JMRI

download page http://jmri.sourceforge.net/download

This user guide assumes you are using version 4.22, or later.

To install from the USB stick, browse to the directory specific to your

operating system to find the JMRI installer. For example, if your USB stick

drive is D: browse to D:\Windows and double click the JMRI executable found

therein.

Connect the Power Supply

Power supplies packaged with a SPROG II are already connected to the

green pluggable terminal block.

For any other supply used, connect as described below.

 Cut off the low voltage DC plug

 Separate the two conductors for about 3cm

SPROG IIv4 User Guide 7

 Strip 6-8mm of insulation from each conductor and twist the copper

cores of each conductor together

 Insert the positive conductor the +V terminal and tighten the screw

 Insert the other conductor in the 0V terminal and tighten the screw

SPROG II is protected against reverse polarity connection of the power

supply but will not work unless the polarity is correct.

The power LED will only illuminate steadily when power is connected to a

SPROG IIv4 and the USB is connected to the host computer (next step).

The power LED will only illuminate steadily when power is connected to a

SPROG IIv3.

The power LED will flash when power is being applied to the track ouput.

Install the USB Drivers (if required)

Please refer to the appropriate document for your operating system on the

SPROG DCC Ltd website https://www.sprog-dcc.co.uk/download-page.

Getting Started with JMRI (DecoderPro and PanelPro)

DecoderPro and PanelPro are different interfaces to the same underlying

JMRI software. The split exists for historical reasons only. There are some

differences in the functions that are available from the menus but a lot of

features are available through both interfaces.

It has become customary to think of DecoderPro as the tool for programming

decoders and PanelPro for controlling a layout.

DecoderPro will often be used with a dedicated programming track for

‘service mode’ programming. This allows full read and write access to all

Configuration Variables (CVs) in a single decoder.

PanelPro will often be used with ‘on the main’ or ‘ops mode’ programming in

conjunction with layout control. In this mode CVs may be written, but (without

special hardware such as Railcom) values cannot be read back. The SPROG

II does not support reading from decoder in ops mode. The advantage of ops

mode programming is that any loco, out of all the locos on a layout, may be

programmed. Unlike service mode there is no single loco limit.

We will use that distinction (DecoderPro for service mode programming and

PanelPro for ops mode programming) in discussing the use of the SPROG II.

SPROG IIv4 User Guide 8

Setting the JMRI Connection Preferences

Now start DecoderPro by double clicking the icon that was placed on the

Windows desktop during the installation.

Click the arrow in the System manufacturer field and scroll down to select

SPROG DCC.

Then in the System connection field, select SPROG (not SPROG Command

Station just yet!). This will create a connection for using the SPROG as a

programmer. To use the SPROG as a command station you would select

SPROG Command Station.

Click the arrow in the Serial Port field and select the COM port noted during

driver installation.

Do not select any other fields at this time.

Click “Save” at the lowest left of the window.

Click “Yes”. DecoderPro will save the new settings and exit.

SPROG IIv4 User Guide 9

Connect the Programming Track

The programming track MUST be isolated from all other DC or DCC

control systems and connected only to the SPROG II. Damage may

result to the SPROG II or other equipment if this rule is not followed.

Connect the SPROG II to the programming track using the “Track” terminals

of the pluggable terminal block. There is no requirement to observe any

particular polarity when connecting the programming track. The DCC output

voltage will be approximately 1V below the power supply voltage, typically

about 11V with the standard power supply provided.

During programming the track current is sensed 100 milliseconds after the

programming track is powered up. If the current exceeds 250 milliAmps then

the programming track power is removed to avoid potential damage to an

incorrectly installed decoder.

SPROG IIv4 User Guide 10

Getting Started with DecoderPro

See the DecoderPro website http://jmri.sourceforge.net for any updates and

latest information.

Join the JMRI group https://groups.io/g/jmriusers/topics for help from other

DecoderPro users and the team who develop it.

Ensure that all software and drivers are installed and that DecoderPro

preferences have been setup in accordance with the previous steps.

Start DecoderPro. The main window will open and show the current

connection status. In the following example “Service Mode Programmer

SPROG Programmer Is Online” shows that the connection is setup to use the

SPROG as a programmer, rather than a command station. In command

station the Operations Mode Programmer would be available instead.

Click “New Loco” to open the Programmer Setup window. A new window will

pop up which shows a list of decoder manufacturers.
