A standard Ethernet connector is provided for use as
the primary programming interface.
The Trio programming software, Motion Perfect v3,
must be installed on a Windows based PC that is
fitted with an Ethernet connection. The IP address is
displayed on the MC4N display for a few seconds after
power-up or when an Ethernet cable is plugged in.
Ethernet cable must be CAT 5 or better.
The Standard Ethernet connection may also be used for
Ethernet-IP, Modbus and other factory communications.
See back page for set-up details.

Ensure that:
1. The shield screw is grounded as close to the
MC4N as possible.
2. 0V connection is NOT used for terminating
screens.
3. Pin 5 of Encoder/Stepper plug is connected
to 0V on drive.
4. Encoder cable screen is clamped to 9 way D
shell.
5. The MC4N 24V supply has common 0V with
the drive(s).
When wiring MC4N Stepper output to a
differential input stepper drive, use the 0V
and shield connections shown for the encoder.
The stepper drive must have its common 0V
connected to the MC4N.

drives and I/O devices are normally connected
in a chain.

An internal relay may be used to
enable external amplifiers when the
controller has powered up correctly
and the system and application
software are ready. The amplifier
enable is a single pole solid state
relay with a normally open “contact”.
The enable relay contact will be open
circuit if there is no power on the
controller OR an axis error exists OR
the user program sets it open with
the WDOG=OFF command.
RTEX drives will be enabled via the RTEX network so the
“Amplifier Enable” connection is not normally required.
All non RTEX stepper and servo amplifiers MUST be inhibited
when the amplifier enable output is open circuit
An additional safety relay may be required so as to meet
machine safety approvals.

DISPLAY The IP address and subnet
mask of the MC4N is
shown on the LCD display
for a few seconds after
power-up. The factory
default IP address is
192.168.0.250. This can
be changed using the
IP_ADDRESS command
via the Motion Perfect v3
software tool.
See back page for set-
up details.

CAN 24V
This is a 5 way 3.5mm pitch connector. The
connector is used both to provide the 24 Volt
power to the MC4N CAN circuit and provide
connections for I/O expansion via Trio’s CAN
I/O expanders. A 24V dc, Class 2 transformer or
power source should be used.
This 24V input is internally isolated from the I/O
24V and main 24V power.
5-WAY CAN
CONNECTOR
The CAN connector may be left unused. The MC4N is
grounded via the metal chassis. Fit a short shield connection
between the chassis earth screw and the earthed metal
mounting panel / plate.
The SD Card maybe used for storing or transfering programs, recipes
and data to and from the MC4N. The card must be FAT32 format and
a maximum 16Gb size.
SD Cards may be FAT16 formatted when purchaced. Re-format in
a PC to FAT32 prior to use.

M4 screws should be used in
2 places to mount the MC4N
to to an unpainted metal
panel.
The best EMC performance
is obtained when the MC4N
is attached from the Shield
screw (marked) using a flat
braided conductor with
a cross section of 4mm x
1mm. Do NOT use a circular
section wire or run the braid
to a central star point.
Ensure that the ventilation
slots at the top and bottom
of the MC4N are kept clear
to ensure a free flow of air
through the module.

NETWORK SETUP
SwitchPC Laptop MC4N
PC Laptop MC4N
DCHP Server
Example : 192.168.0.100 Example : 192.168.0.250
NETWORK CONNECTION
Set IP_ADDRESS in MC4N to an
available unused address. It MUST
match the subnet in use. Set the PC
to use DHCP server.
Note: the MC4N always has a fixed IP
address.
POINT-TO-POINT OR CLOSED NETWORK
(No DHCP server)
The PC MUST be set to a fixed
IP_ADDRESS.
The first 3 “octets” MUST be the
same as the MC4N and the last MUST
be different, but not 000, 254 or
255.
SETTING A FIXED IP ADDRESS
In Windows 7. Open “Network
and Sharing Centre” then change
“Adapter Settings”. Select
the properties of the Local
Area Network and the IPv4
properties. The IP Address is set to
192.168.0.100 with subnet mask set
to 255.255.255.0. Assuming that the
MC4N has IP_ADDRESS=192.168.0.250
or similar.
