MX31 Cab, MX31FU Radio Cab Page 21
tional communication is implemented in decoders. Until then, “SENT” is displayed as an internal
system confirmation only.
The
key
switches the cab to
binary programming,
where the
display in addition to the decimal values also displays the binary
code and the number keys no longer are used to enter digits but to
invert Bit values with the 0 .. 7 keys instead with 0 referring to the
rightmost least significant bit. The resulting decimal value is con-
tinually updated and displayed as well. Pressing the
key again,
exits the cab from the binary programming.
After a CV is edited, a
new entry (another CV)
can be started by
pressing the
C key,
where a new CV number can be entered,
value changed etc. The C key can only be used that way after a
CV editing operation is finished (accepted with the “A” key), be-
cause the “C” key acts as the “cancel” key while editing!
The data content of a CV can be
read-out
in “service mode” (and
in the future thanks to bidirectional communications in “operations
mode” as well). Press the
“A” key twice
after the CV number is
entered to start the read-out.
WHERE TO AND BACK? Returns to the LOCO or SWI mode.

Exit programming procedures with the
E key.
In contrast to the E-procedures, the E key is the only
way to exit the programming procedure, since decisions whether to accept the programming steps
have already been made.
ERROR MESSAGES
Err0: Stand-by voltage at start of programming less than 12 V.
Err1: Voltage test timed out.
Err2: Over current at start of programming (higher than 250 mA)
Err3: Voltage too low for current consumption (rise of more than 60 mA is necessary)
Err4: No decoder acknowledgment (doesn’t necessarily mean unsuccessful programming. Could
also be because no consumers like head light or motor are connected or the current consumption of
those is too low, thus decoder read-out is not possible.
Err5: Over current at programming output end stage
Err9: Selected register does not exist.
