Page 4 MX31 Cab, MX31FU Radio Cab
1. Introduction
This document describes the MX31 cab, the radio version MX31FU and the radio base module
MXFU.
The MX31 is designed to operate with the MX1 model 2000, MX1HS or MX1EC command station.
Certain restrictions apply when the MX31 is used with older command stations like the MX1/N and
MX1/MULT.

3. Connecting cab’s to command station
Each cab contains two identical sockets (internally parallel) for the CAN Bus connection to the com-
mand station. All cabs connected to the system (including different types) are connected in parallel,
usually by connecting a cable from the command station to the first cab and from there on to other
cabs, as shown below. Prefabricated cables in standard and custom length are available from ZIMO
(see pricelist), but can easily be homemade.
The cable, connectors (50 per package) and the
required special pliers are also available from
ZIMO.
As an alternative to daisy-chaining the cabs, a 6-
conductor wire can be installed with outlets
around the layout. Distribution boxes are also
available (see ZIMO pricelist).
With most applications that have a maximum of
10 cabs and the total CAN bus length is limited to
150 feet (50m) no special considerations are re-
quired when connecting cabs to the command
station (For example: no more than 2 cabs at the end of a 150’ (50m) cable, no more than 5 cabs at
the end of a 60’ (20m) cable). If the number of cabs or the total CAN bus cable length exceeds these
limits, certain precautions have to be followed such as installing termination resistors (type. 150 –
330 Ohms) between the two center conductors at the end of the CAN bus and/or a separate power
supply for the CAN bus. Please contact ZIMO if necessary!
