Mounting
Screw the M220nx into an enclosed panel
using the mounting holes provided on the
cover plate. Be sure to leave about 2 inches (5
centimeters) on each side for wiring.
Addressing
Before setting or changing the address, make
sure the M220nx’s power is off. The M220nx
only reads the address when the module is
turned on. After changing the address, you
must transfer memory to the module. Refer to
“Transferring Memory”on page 8.
The M220nx has two rotary switches for
assigning the module’s CMnet address. One
switch corresponds to the tens digit and the
other corresponds to the ones digit. For
example, if the module’saddressisthree,set
the tens switch to zero and the ones switch to
three, as shown in Figure 2.
Power Wiring
Whenever possible, make sure the module’s
power and communications connections are
working properly before connecting any input
or output points.
CAUTION The M220nx module is a Class 2
device (less than 30VAC, 100VA maximum).
Take appropriate isolation measures when
mounting the M220nx module in a control
panel where non-Class 2 devices (for
example, 120VAC) or wiring are present.
You can power several modules from the
same transformer if you maintain the same
polarity.

Revised 4/3/00 •M220nx 4 © 2000 Automated Logic Corporation
The M220nx has an operating range of
21.6VAC to 26.4VAC. If voltage measured at
the module’s power input terminals is outside
this range, the module may not work
properly.
1. Turn the module’s power off. This
prevents the module from being powered
up before the proper voltage is verified.
2. Make sure the 24VAC power source is off.
3. Connect the power wires to the module’s
power terminals labeled Gnd and 24VAC
(see Figure 1 on page 2 for location).
4. Apply power to the transformer.
5. Make sure that 24VAC is present at the
module’spowerinputterminals.
6. Set the module’s address. Refer to
“Addressing”on page 3 for details about
setting the address.
7. Turn the module’s power switch on.
When the module turns on, the Run and
Power LEDs turn on. The Run LED begins
blinking and the Error LED turns off. See
Table 5 on page 8 to troubleshoot the
LEDs. If the module does not respond,
call Technical Support at [phone].
CMnet Communications
A CMnet is a peer to peer network that allows
multiple control modules to communicate
over an EIA-485 standard. A token passing
scheme is used to control access to the
network. A CMnet may be configured as a
legacy CMnet at 9600 bps or 38.4 kbps or an
ARCNET CMnet at 156 kbps. The ARCNET
CMnet configuration provides BACnet
compatibility, as well as better performance
over a legacy CMnet. All modules on a CMnet
must communicate at the same speed.
When communicating at 156 kbps, the CMnet
uses a unique implementation of the industry
standard ARCNET protocol called ARC156.
For a summary of the differences between
ARCNET and ARC156, please refer to the
156K CMnet Wiring Technical Instructions.
Using the M220nx on an ARC156
CMnet
Use the appropriate wire for CMnet
communications. When communicating with
the ARC156 protocol use an A3ARC156 wire
available from:
Magnum Cable Corporation
Cleveland, OH 44110-0500
[phone]
When the Comm Select jumper is set to
ARC156, the CMnet port is connected to an
ARCNET processor, enabling the M220nx to
communicate on an ARC156 CMnet.
Communication speed is 156 kbps regardless
of the Baud Select jumper setting (see below).
Using the M220nx on a 9600 or
38.4K bps CMnet
Use a dedicated 22AWG to 18AWG twisted
pair wire for legacy CMnet (EIA-485) wiring.
When the Comm Select jumper is set to
CMnet,themodulecommunicatesona
legacy CMnet at the baud rate set by the Baud
Select jumper (see the following diagrams).

Communicating with the
Wo r k s tat i o n
You can connect a workstation or portable
computer directly to the M220nx module
using an APT and the module’sAccessport
(see Figure 3). This type of connection can be
used to troubleshoot the module or transfer
memory. If you are using an ARC156 CMnet,
you can receive colors while connected to a
module’sAccessportifagatewaymoduleis
on the CMnet. You cannot receive alarms
through the Access port, however.
The Access Port’sbaudrateisdeterminedby
the Baud Select jumper on the module.
1. Connect the computer’s serial port to the
EIA-232 port of the APT using a standard
straight-through serial cable.
2. Set the APT’s Mode Select switch.
•On an ARC156 CMnet, use the TTL
setting.
•On a legacy CMnet, use the 485 setting.

to 5VDC source must not exceed
10kohms. The input impedance of the
M220nx is approximately 1Mohm.
•0 to 20mA: The input resistance on the
“A”input is 250 Ohms. The “B”terminal
supplies a voltage source to power the
4-20mA transducer. The “B”terminal is
capable of supplying 18 to 24VDC, but
the total current of both “B”terminals
must not exceed 40mA. If the voltage
measured from the “B”terminal to Gnd
is less than 18VDC, you need to use an
additional external power supply.
•Dry Contact: A 5VDC wetting voltage is
used to detect contact position. This
results in a 0.5mA maximum sense
current when the contacts are closed.
The M220nx accumulates up to ten input
pulses per second.
1. Be sure the M220nx’s power is off before
wiring any inputs or outputs.
2. Connect the input wiring to the screw
terminals on the module as shown in
Figure 4.
NOTE If a 4-20 mA sensor uses an
external 24VAC power supply, connect
one leg of the 24VAC supply to the module
ground.
3. Set the configuration jumper for each
input to indicate the type of input used.
Make sure the jumper is positioned
correctly, and be sure to grip the jumper
by the sides only. See Figure 5 on page 7.
4. For each input, enter the channel number,
offset, and gain on the Function Block’s
Parameter page in SuperVision. Valid
channel numbers are listed in “Channel
Numbers”on page 7.
5. To verify each input’s operation, have
each sensor create a known value and

To verify each output’s operation, lock the
output to a known condition using the
Function Block’s Parameter page, then make
sure the equipment actually operates as
specified.
Each digital output can be placed in Manual
or Auto mode by setting the HOA switches
(see Figure 1 on page 2 for the switches’
location). You can monitor the status of the
HOA switches through SuperVision by
assigning each switch a digital input in the FB
using channel numbers 81 and 82.
An off status on these channels means the
HOAswitchisinAutomode.Anonstatus
means the HOA switch is in Manual mode.
Channel Numbers
The following tables show the valid channel
numbers for each point on the M220nx. Enter
the channel number, offset, and gain for each
point in Eikon before the Function Block is
made, or on the FB’s Parameter page in

Troubleshooting
Formatting the Module
When you are unable to communicate with a
module, you can, as a last resort, manually
format the module to try to restore
communication. Formatting the module
erases all memory, so you need to transfer
memory back to the module once it is
formatted.
1. Turn the module’s power off. Make sure
the module’saddressswitchesarenotset
to ’0,0’.
2. Press and hold the Format button (see
Figure 1 on page 2 for location).
3. While continuing to hold the Format
button, turn the module’s power on.
4. Continue to hold the button until the Error
LED flashes three times in sync with the
Run LED.
5. Release the Format button.
6. Transfer memory to the module. Refer to
“Transferring Memory”.
