The short circuit protection is carried out for the total current of all outputs. Use the “soft start” op-
tion (i.e. CV #125 = 52) to prevent cold-start problems of light bulbs (in-rush current interpreted as a
short circuit, which leads to the output being turned off!
Software - Update:
ZIMO decoders can be updated by the user, provided that one of the following update devices is at
hand: ZIMO decoder update-module
MXULF
(since 2011), system-cab
MX31ZL
or
command sta-
tion MX10
. The updating process is carried out via a USB stick (MXULF, MX31ZL / MX10) or a PC
with Windows operating system and the program ZIMO Firmware Flasher (within the ZIMO Sound
Programmer
ZSP)
.
The same hardware together with the program ZSP is also used to load sound projects into the de-
coder.
There is
no need to remove the decoder or to open up the locomotive.
Just set the locomotive on
a track section connected to the update module and start the update with the computer or other
equipment mentioned above.
