Page 4: Installation
Installation Connection to the SBOOST II is via 4-way pluggable terminal blocks as shown below. The following steps are required to install SBOOST II before you can use it for the first time: Version 1.1 June 2015 © Copyright 2015SPROG DCC Ltd... -
Page 5: Connect To The Power Supply
SPROG II for both the DCC signal and to supply power to the SPROG II (See below), see the picture below. Connect the SBOOST II DCC inputs “In A” and “In B” to the SPROG II track outputs. - Page 6 17V, a separate power source, of the correct voltage, must be used for the SPROG II. For SBOOST II supply voltages in the range 15 – 17V you can use a separate power supply or insert a string of 3 1N4001 (or similar) diodes in series with the +V connection to drop the voltage slightly.
- Page 7 NO common wiring between power districts. If a single power supply is used to power more than one SBOOST II it must be rated to supply the maximum current to all SBOOST II simultaneously.
- Page 8 The power supply must be able to supply the full rated current (e.g., at least 5 Amp for 2 x SBOOST II). Power districts must be separated by isolation gaps in both rails. The SPROG 3 (or SPROG II) can be powered from one of the SBOOST II To further SBOOST Isolation Gap Power Version 1.1 June 2015...

- Page 10 SPROG 3, SPROG II or other booster and SBOOST II daisy-chained with common power supply. Using a SPROG 3 (or SPROG II or other booster) and SBOOST II in this way is not recommended. A short circuit in the SPROG 3 power district will affect the DCC signal to the SBOOST II, resulting in the loss of the DCC signal in the SBOOST II power district.
- Page 11 SPROG 3, SPROG II or other booster and SBOOST II with separate power supplies. Using a SPROG 3 (or SPROG II or other booster) and SBOOST II in this way is not recommended. A short circuit in the SPROG 3 power district will affect the DCC signal to the SBOOST II resulting in the loss of the DCC signal in the SBOOST II power district.
- Page 12 SBOOST II User Guide Auto-reverse Operation The SBOOST II can be configured for auto reverse operation, e.g., to supply power to a reverse loop or wye formation as a separate power district. To enable or disable auto-reverse operation you must open the casing of the SBOOST II and fit or remove a jumper link.
- Page 13 When a jumper link is fitted, auto-reverse operation is enabled. Auto-reverse operation must not be enabled in adjacent power districts. This may cause “thrashing” as both SBOOST II try to auto-reverse simultaneously. For UK customers, spare jumper links may be obtained from SPROG DCC Ltd on receipt of a stamped self-addressed envelope.
