Description and introduction

Parameters:
Power supply 7~18V DC, recommend 12~18V DCC

Decoder is supplied directly from DCC signal (line), it is highly recommended use signal booster. Power consumption is ca 300mA at running of servo (max is depended of type of servo and load), <70mA v at idle. Power consumption are at 15V DC.

Firmware is according to:
NMRA S-9.1/2006 – DCC electrical standard
NMRA S-9.2.1/2012-7 – DCC Extended Packet Formats

Heads up
During servo’s movement, board not catching DCC signal due to accurate timing of servo’s movement.
All settings, i.e. limits, DCC address, last position etc are stored in internal EEPROM and are stored even after power supply interruption.

LED1 is connected with relay K1 (connector X3) – when LED1 lit relay is switch to NO
LED2 is connected with relay K2 (connector X2) – when LED2 lit relay is switch to NO

After connection of power line (DCC) servo will move to last know limit position with delay calculate from DCC address. For example, board has address 2, servo will start moving 2 seconds after power up, next board has board for example address 4 so that servo will move 4 second after power up. This is important against to overload power supply at start-up.
