Synchronous update for accessory decoders MX820, MX821
This method removes a problem especially known with large-scale layouts: decoders built-in to turnout
casings (e.g. LGB) have to be removed and connected individually to a decoder-update-device to load an
update.
Using the
synchronous update
, the decoders can stay on the layout, the decoder-update-device MXULFA
is connected instead of the digital command station and sends the new software to all accessory decod-
ers. Every single accessory decoder then has the possibility to request a repetition by negative acknowl-
edgements, until all decoders have the update installed. Vehicles can usually stay on the tracks during
this procedure.

9. Driving operation with MXULFA
The MXULFA is also a small command station with max. 2A This allows test drives to be completed after
sound loading or CV programming. You can only drive with the MXULFA (version with display).

ATTENTION:
the MXULFA, or the power supply connected, is limited in its efficiency. The current draw
of connected consumers (including vehicles which are placed on the layout) as well as the inrush-cur-
rent at power-up can lead to a shut-down due to a short circuit.
NOTE:
the searching process can take up to 2 seconds per decoder.
