Digital - DCC Zentrale - Minibox 2 - Features und Spezifikationen

FREMO Minibox 2 


Entwickelt von Pål Olson, und prinzipiell als reine Fahrzentrale konzipiert.
Die Minibox 2 kann auch für Stellwerke verwendet werden. Eine Pufferung (Tracking) von Schaltbefehlen erfolgt nicht - das müssen die anderen Komponenten selbst erledigen.

Nachfolgendes gilt für Firmware Version 2.3 (erschienen ca. 2020):

The Minibox2 is normally just plug-n-play.
Power it up, and its Heartbeat/Status LED should light with a short blink every 2 sec indicating RUN-mode. 
Plugging in a FRED should give activity on Loconet, thus blink the LN-LED.

The Minibox2 supports:

  • RUN-mode (default at power up)
  • IDLE-mode (short flash every 1 sec) - rail-sync on sending only DCC IDLE-packets, and 
  • STOP-mode (slowly blinking 1 sec on, 1 sec off) - rail-sync off.

If it’s blinking fast - then either it’s an error, or it is in boot-loader mode - which should not happen by accident…

Setting Minibox2 in different modes is done by e.g JMRI or any (Digitrax) throttle having the run/stop/idle button.
Anyway, the Minibox2 does always power up in RUN-mode.
