MAKING CONNECTIONS
3.1
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 SiteLink module is a Class 2 device (less than 30VAC). Take appropriate isolation
measures when mounting the SiteLink module in a control panel where non-Class 2 devices
(120VAC or greater) or wiring are present.
You can power several modules from the same transformer if you:
• maintain the same polarity
• use a transformer whose power rating is at least 20% greater than needed for the modules
For example, if the transformer is rated for 50VA and you connect it to two modules each rated at
20VA, the power trunk uses a recommended 80% of the transformer’s power (20+20=40).
!
CAUTION
Do NOT turn the module on. The module should be turned on by a factory trained specialist
only.
The SiteLink has an operating range of 21.6VAC to 26AVAC. If voltage measured at the module’s
power input terminals is outside this range, the module may not work properly.
Figure 5
Power connections
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).
4. Apply power to the transformer.
5. Make sure that 24VAC is present at the module’s power input terminals.
6. Set the module’s address. Refer to 4.0 - Addressing 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 and the Run LED begins blinking. (See
Figure 1 for location of the LEDs.)

IGM - Liebert Equipment
Information Gathering Module Network is the protocol SiteLink uses to communicate to Liebert units
over the EIA-422 connection type. IGM is a point-to-point protocol, where one device connects directly
to another and only those two devices communicate with each other.
NOTE
If shielded cable is used, connect the shield wire to earth (ground) at the Liebert equipment. Do
not ground the shield at the SiteLink.
Figure 6
3.3
IGM connections
ARCnet / CMnet
The SiteLink module can connect to an EIA-485 CMnet through the CMnet port at 9600 bps,
38.4 Kbps or 156 Kbps. Use a baud rate of 156 Kbps to communicate on a BACnet over ARCNET
156 Kbps network. When communicating at 156 Kbps, the CMnet uses a unique implementation of
the industry standard ARCNET protocol called ARC156.
1. Be sure the module’s power is off before wiring it to the CMnet.
2. Check the network communication wiring for shorts and grounds.
3. Connect the CMnet wires to the module’s screw terminals as shown in Figure 7. Be sure to follow
the same polarity as the rest of the CMnet.

Connection Considerations
Port A on the SiteLink is capable of several types of connections:
• EIA-232
• 2-wire EIA-485
• 2-wire or 4-wire EIA-485/EIA-422
Differences Between EIA-485 and EIA-422
Third-party manufacturers sometimes specify a device as either EIA-485 or EIA-422.
EIA-485 and EIA-422 terminology is interchangeable for the following reasons. Both can have 2-wire
or 4-wire connections, but an EIA-422 connection needs 4 wires to achieve two-way communication.
An EIA-422 4-wire network actually consists of two EIA-422 2-wire one-directional networks communicating between the same devices.
The reason for the one-directional limitation is that an EIA-422 transmitter cannot turn off automatically after transmission. An EIA-422 transmitter that is on—even when not sending data—will prevent another transmitter from effectively sending data.
An EIA-485 transmitter, by contrast, can turn on and off between transmissions. This feature makes
a 2-wire connection possible and preferable for many reasons, including the fact that 2-wire networking allows for daisy-chaining with no need to designate any devices as master, as 4-wire requires.
The only advantage of 4-wire over 2-wire is that 4-wire allows full duplex communications; however,
since very few protocols need full duplex communications, there is little practical reason to run 4-wire
EIA-485. Although technically there are voltage and driver load differences between EIA-485 and
EIA-422, the differences are indistinguishable in normal use.
Liebert recommends using a 2-wire connection unless:
• you are communicating with a device that uses EIA-422 or
• the third-party device does not support 2-wire EIA-485.
Use of the two terms—EIA-422 and EIA-485—can be confusing in engineering drawings. When drawings include SiteLink wiring details, Liebert suggests labeling any occurrences of EIA-422 as
“EIA-422 (EIA-485 4-wire).”
Termination
You can reduce reflections that cause communication and data errors on EIA-485/EIA-422 networks
by terminating a data cable with a value equal to its characteristic impedance. Although termination
is often unnecessary on networks where the baud rates are slow or the cables are short, termination
becomes important as the baud rate increases.
Resistors acting as terminators typically have 120-130 ohms, although twisted-pair cable impedances
can be as low as 100 ohms. Liebert recommends 120 ohm terminating resistors on EIA-485/EIA-422
networks. You must apply a value that closely matches the cable impedance as near as possible to the
ends of the network segment.
NOTE
Some third-party manufacturers provide a resistor within a device, using a jumper to disable
the termination option if termination is not required. If you are using one of these devices,
make sure that only devices that require termination are set to have termination.
6
Making Connections
Bias
Data collisions occur when two devices enable their transmitters at the same time; these are likely to
occur on EIA-485/EIA-422 networks. A master/slave protocol has one master and many slaves. The
slaves are always listening and respond only when they hear their address in the master’s request for
information. When the master is not transmitting, the network will float, enabling noise to falsely
trigger one of the slaves’ receivers, since the receiver’s output is undefined when the receiver’s input
voltage is between 200mV and -200mV (known as the undefined state).
You can apply bias to the network to ensure that the network assumes a defined state even when all
device transmitters are off.
When bias is used with terminators, the float network state’s voltage exceeds 200mV. This means
that:
• The receivers are biased in the mark state (OFF, logic 1) when the network is idle or when the
transmitter sends a logic 1.
• During the transmission of a logic 0 (less than -200mV), the network will be in the space state
(ON, logic 0).
Liebert’s DIAG boards can serve as bias on EIA-485/EIA-422 networks. Apply bias in the middle of
the network, and apply termination only at the two end devices.

EIA-485 Connection—2-Wire (Default)
NOTE
Port A is recommended for 2-wire EIA-485—the default setting for the module.
When connecting the SiteLink to a BMS that uses 2-wire EIA-485:
• The recommended wiring is shielded, 18-24AWG twisted pair.
• The distance from the SiteLink to the first EIA-485 device depends on the communications baud
rate; on average, this distance should not exceed 3,000 ft. (914.4m) at 9600 baud.
• Keep in mind that repeaters are often required when connecting 32 or more EIA-485 devices or
when using long runs of wire. Refer to your BMS documentation for information on when to use
repeaters.

Verify Communication on the CMnet
To verify that the SiteLink is communicating on the CMnet, make sure the CMnet transmit and
receive LEDs are active.
NOTE
Before setting or changing the address, make sure the SiteLink’s power is Off. The SiteLink
reads the address only when the module is turned On. After changing the address, you must
transfer memory to the module.
The SiteLink has two rotary switches for assigning the module’s CMnet address, as shown in
Figure 14. The switch at left corresponds to the tens (10s) digit, the one at right to the ones (1s) digit.
For example, if the module’s address is three (3), set the tens switch to zero (0) and the ones switch to
three (3).

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.
