SPROG II / 3 / nano DCC

Content → Command Stations → SPROG II / 3

The SPROG II / 3 and SPROG nano are relative easy to use and economically priced DCC Generator/Programmer with some extras.

• 128 loco slots
• auto purging
• 14, 28 and 128 speed steps
• 28 mobile decoder functions
• programming on the main (OPS)
• service track programming (The S-Nano does not support a service track.)
• stationary DCC decoders

• Only the default speed step is supported for rolling road: 128¹

¹) The mode word is currently not changed if the speed step of a loco is not set to 128.

Rocrail sends every 25ms a byte string like "O 73 3F CC 80" as a command to SPROG II which on its turn generates the real DCC packet on the track output.
This byte string is a hexadecimal representation of the DCC packet to be send. A complete refresh cycle will take about 4 seconds if all 128 slots are in use.

Unique name of this controller.

The serial device connected with the SPROG.
SPROG 3 and S_Nano have device name "/dev/ttyACM0" under Linux.

The purge time in seconds before a locomotive will be purged if no commands has been send.
Setting this value to zero will disable purging.

The Pi-SPROG can only be used if Rocrail runs on the Raspberry Pi on which the Pi-SPROG is connected.
Pi-SPROG has the device name "/dev/ttyAMA0" under Linux/Raspbian.

Use the RCAN/CBUS library with serial 115200, and as device /dev/ttyS0.

Note: The Pi-Sprog must be powered on at Raspberry Pi boot.

The serial BPS must be set to 460800.
