1Introduction
The E2 controller is a microprocessor-based control
system designed to provide complete control of compressor groups, condensers, refrigerated cas
ponents related to refrigeration and building control. The
E2 is the controlling
uration (RS485 I/O, Echelo n
Ethernet) that includes input and output communication
boards, remote communication software, and a variety of
sensors, probes, and transducers.
The E2 efficiently operates all systems that support

3.4.1.3 Mounting the Four-Channel Repeater
The four-channel repeater (P/N 638-4830) serves the
same basic function as the two-channel repeater: boosting

useful as a means of connecting the E2 to its associated
devices using more than one daisy chain.

5.1 Overview
E2’s Serial Configuration is the centralized location
where all communication ports (COM ports) may be set up
in the E2 controller. To support the increasing number of
third-party devices that E2 can communicate with, E2 has
the expanded flexibility of dynamic COM ports that will
support different types of communication protocols to
meet the specific needs of the user.
Previously, all COM ports were pre-defined to support
specific type of serial device. E2 now has five configu-
a
rable COM ports that can communicate with different
ces on the network.

6 The RS485 Network and Hardware Setup
Previous versions of E2 hardware and firmware before
version 2.30F01 only supported one I/O network port,
with an optional expansion card that could be used for
connection to Copeland ISD compressors or IMC/Prodigy
S-Bus rooftop unit controllers. Beginning with E2 version
2.30F01, E2s now have up to three RS485 network ports,
each of which may be configured as an I/O network, IMC/
Prodigy, ISD, or ECT MODBUS port.
Section 5, Serial Configuration of this manual covers
how to assign COM ports COM2, COM4, and COM6 to
different RS485 network types.
Section 6 (this section)
explains the network types, the hardware that may be connected to each type, and how to configure the devices.
6.1 The I/O Network
All boards and controllers manufactured by Emerson
Retail Solutions for communication with E2 via RS485 are
generally referred to as I/O boards, and the network they
are connected to is referred to as the I/O network
(or I/O Net).
A COM port configured as I/O Net may connect with
up to 127 I/O boards. This network is used by the E2 to
read data from the input boards and to send commands to
the analog and digital output boards. Some unit control
lers, such as CCB case controllers and MultiFlex RCBs,
also communicate with the E2 via the I/O Network.
6.1.1 I/O Board Names and Terminology
There are many input, relay output, analog output, and
combination I/O boards available from Emerson Retail
Solutions for use with the E2. However, separate from the
various MultiFlex unit controller models, E2 only recog
nizes four different types of I/O boards: 16AI, 8RO, 4AO,
and 8DO. All E2-compatible I/O boards communicate
with E2 as if they are one or more of these types of boards.
In this manual and in the E2 interface, when you
encounter these board names, bear in mind that they are
terms that represent many types of boards.

With X as the number of plus boards and Y as the number of non-plus boards, use the following equation to
ensure th
at the number of devices on your network has not
exceeded the maximum load limitation of the network. For
example, if the total number of devices is less than 256,
the maximum load limitation has not been exceeded.
X + (Y • 8) < 256
6.1.3 Wiring Types
Emerson Retail Solutions specifies all RS485 I/O and
MODBUS wiring used by the E2 must be Belden 8641
(24A WG, 300V, Emerson Retail Solutions P/N 135-8641);
Belden 8761 (22 AWG, 300V not stoc ked by Emerson
Retail Solutions); or a 600V-shielded 22AWG equivalent
stocked by Emerson Retail Solutions (P/N 135-0600).
These are two-connector shielded twisted pair cables that
support a maximum daisy chain cable distance of 4000
feet (1219 m) between the E2 and the end device on the
network.
The MultiFlex-plus board contains a replacement
RS485 transceiver chip that presents less of a load on the
network than a non-plus board. This increases the maximum number of devices that can be
placed on the network,
but not the number of board types an Einstein controller
can communicate with.
The MultiFlex-plus board now
accounts for only 1/8
the load of a non-plus board with 32 total devices on the
network (one Einstein controller + 31 boards). This new
conversion allows for the placement of 256 devices on the
network (one Einstein controller + 255 boards). The number of boards an Einstein controller can support is
increased
from 31 up to 255 using MultiFlex-plus boards
only. In other words, the number of I/O net devices are no
longer restricted by the I/O net 31-node limitation.
NOTE: The MultiFlex-plus board replaces the
old-style MultiFlex boards and is currently
being shi
pped.
6.1.2.1 Board Designation
Plus boards are always identified with a plus (+) sign
that appears on the plastic insulating cover on the top of
the board, after the board name.
6.1.4 The I/O Network Structure (Daisy Chains)
The RS485 Input/Output (I/O) Network connects all
input and output communication boards together in a single open communications loop

6.1.5 Network Noise Minimization
Site environments will frequentl y hav e nu merous
sources of high EMI, or “noise,” that must be accounted
for when routing RS485 network cable. Although the
cable is shielded against noise,
best practices for minimizing network noise.
In general, installers should follow these guidelines
when installing RS485 networks:
• Avoid running cable next to noise-generating
devices, such as motor starters, contactors, invert
ers, fluorescent light ballasts, arc welders, etc. If
possible, keep cable less than 1 foot away from
noise-generating devices (ideally, at least 5 feet).
• Do not run RS485 cable in the same conduit as
high-voltage wiring, such as 120VAC or 240VAC
power wiring. Keep RS485 cable a minimum of 3
inches away from high-voltage wiring (ideally, at
least 12 inches). If RS485 must cross paths with
high-voltage wiring, cross them perpendicular —
running RS485 and high-voltage wire in parallel
increases the amount of noise induced on the net
work.
• Ensure you are grounding each input device’s 0V
power terminal to a separate earth ground, and set
ting the termination and biasing jumpers as
instructed in
and Biasing Jumpers.
For more instructions on best practices for minimizing
noise, refer to publication 026-1903, E2 Controller Wir
ing Practices, available in the Product Manuals section of
the Emerson Climate Technologies Web site:

6.1.6 Network ID Numbers (Board Numbers)
Each device on an RS485 segment has either a network
dip switch or rotary dials that must be used to assign the
board a unique network ID number.
The network ID number makes a board unique from
other boards on the network of the same ty pe. This allows
E2 to find it and communicate with it easily.
Boards of the same type should be numbered in
sequence, starting with one and continuing with two,
three, and so forth. For example, if a segment contains
four 16AI boards and five 8RO boards, you should num
ber the 16AIs one, two, three, and four; and the 8ROs one,
two, three, four, and five. The same should be done with
multiple 4AO and 8DO boards, and IRLDS leak detection
units.
-
For all boards, except 8IO and 8DO boards, the network dip switch labeled S1 (or S3 for the 16AI board) is
used to set the unique board number of the unit and the
baud rate. The 8IO and 8DO uses rotary dials to set the
board number of the unit.
Numbering the MultiFlex Combination I/O Boards
When it comes to network numbering, the MultiFlex
Combination Input/Output boards (88, 88AO, 168,
168AO, and 168DO) are special cases. They are actually a
combination of three types
boards: the inputs are configured like a 16AI, the relay
outputs are configured like an 8RO, and the analog outputs
are configured like a 4AO.
When a MultiFlex combo board is present on the network, it must be addressed like all three board types.
Therefore, when numbering these boards, you must set a
unique number for both the 16AI, 8RO, and 4AO compo
nents of the board.
Addressing the MultiFlex Boards
For MultiFlex boards, set positions 1 to 5 on S3 for the
16AI component and positions 1 to 5 on S4 for the 8RO
component. Set positions 6 to 8 on S4 for the 4AO or 4DO
segment. For MultiFlex board controllers, use positions 1
to 5 on S3 to set the address.
Addressing the MultiFlex ESR Boards
The MultiFlex ESR uses standard Emerson Retail
Solutions I/O Network addressing. Set positions 1 to 5 on
S1 to set the network ID (address) of the MultiFlex ESR
from 1 to 31.
of Emerson Retail Solutions
6.1.7 Setting the Baud Rate
All I/O boards have dip switches that determine the
baud rate at which they communicate. Currently, the baud
rate dip switch in network components may be set at either
4800, 9600, 19200, and 38400. Setting of the baud rate is
accomplished using dip switches (refer to the board’s
installation sheets at the end of this section for specific dip
switch settings).
Baud Rate for the E2
The baud rate default for E2 is 9600.
Baud Rate for the Gateway
The Gateway can be set to either 9600 baud or 19.2K
baud by dip switch #6. “ON” places the rate at 9600 baud
while “OFF” sets it at 19.2K baud.
Dip switches 6 and 7 control the baud rate at which
the Gateway communicates with the site controller on the
RS485RS485 Network. These switches must be set to the
same baud rate setting as the E2 or REFLECS (usually
9600 baud).

way communicates with the other devices
on the Receiver
Bus Network. This baud rate may only be set to either
9600 baud (switch DOWN) or 19200 baud (switch UP).
All Gateways and receivers on the Receiver Bus Network
must have the same baud rate dip switch setting. It is recommended you use 9600 baud as the Receiver Bus Network baud rate.
Baud Rate for the 8IO, 8DO, and ARTC
There are three I/O devices that do not have baud rates
determined by dip switches. They are as follows:
1. The 8IO -

baud rate being used by the I/O devices on the
network, and adjusts to match their baud rate.
2. Th
e 8DO - this board automatically detects the
baud rate being used by the I/O devices on the
network, and adjusts to match their baud rate.
3. T
he ARTC - this board is fixed at 9600 baud.
Baud Rate for MultiFlex Boards
On all MultiFlex boards, switches 6 and 7 on S3 are
used to set the baud rate. To communicate at 9600 baud,
set switch #6 to the UP position and #7 to DOWN. For
19200 baud, set switch #6 to the DOWN position and #7
to UP.
Baud Rate for the MultiFlex ESR
Set the baud rate on the MultiFlex ESR board by set-
ting switches 6 and 7 on the network address terminal
(labeled S1).

Figure 6-2 shows the proper terminating jumper settings
for the E2 and for all I/O boards.
Figure 6-2
- I/O Network Te rmination Jumper Settings
6.1.9 Powering the I/O Boards
All models of E2-compatible I/O boards require
24VAC Class 2 input power. Some boards such as the
16AI, 8RO, 4AO, 8DO, MultiFlex ESR, and MultiFlex 16
use a center-tapped power source. All other models, such
as the 8IO and MultiFlex Combination I/O boards, may
use non-center tapped power sources.
6.1.8 Setting the Terminating and Biasing Jumpers
The I/O Network connector, for all I/O boards and the
E2, has a set of three terminating jumpers. They are the
jumpers positioned closest to the I/O Network connector.
The E2 has jumpers next to each of the COM ports that
can be configured as an I/O network (COM2, COM4, and
COM6).
The purpose of the jumpers is to provide network termination resistance and network biasing to the two ends,
termination points, of the daisy chain. One device at the
or
beginning and one device on the end must be terminated
and biased by placing all three jumpers in the UP or I/O
position. All other devices on the daisy chain must have all

- Device Power Requirements
To select a power transformer for
a board or a series of
boards:
1. Determine what the total VA is for the boards
that
will be powered by the transformer
(see Table 6-3).
Example: Two MultiFlex 168AOs (15 VA
each), a
nd one 8DO (18 VA) boards are to
be powered by one transformer. The total
VA is:
2. Use a transformer that has a power rating
higher than the total calculated VA
(see Table 6-2).
Example: For boards totalling 48VA, a 56VA trans-
former is sufficient, since 56VA is greater than
48VA.
I/O Board Transformers should be located within 10
feet
of the board it is powering, preferably within the
board enclosure.
6.1.9.1 Wiring Types
For powering I/O boards, use only the listed wire types
from Table 6-4. Three-conductor non-shielded cables are
the recommended wire for connecting between
tapped transformer and the I/O boards. The third conductor should be connected to earth ground. If boards use a
-tapped transformer, also connect the center tap to
center
the earth grounded third conductor.

The wire length from the transformer and the number
of boards connected to the same wire determines the type

is not enough to be concerned with. But it is very important not exceed this maximum wire
length or the boards

6.3.5.1 Overview
The Energy Meter provides a solution for measuring
energy data with a single device. Inputs include Control
Power, CT, and 3-phase voltage. The Energy Meter supports multiple output options, including solid state relay
tacts, Modbus (with or without data logging), and
con
pulse. The LCD screen on the faceplate allows instant output viewing.
The meter is housed in a plastic enclosure suitable for
installation on T35 DIN rail according to EN50022. The
Energy Meter can be mounted with any orientation over
the entire ambient temperature range, either on a DIN rail
or in a panel. The meter is not sensitive to CT orientation
to reduce installation errors.
6.3.5.2 Supported System Types
The Energy Meter Series has a number of different
possible system wiring configurations. To configure the
meter, set the System Type via the User Interface or Modbus register 130 (if so equipped). The System Type tells
eter which of its current and voltage inputs are valid,

6.4 BACnet
BACnet is a communications protocol for building
automation and control networks available for E2 versions
4.02 and above. Any of the three serial ports (COM2,
COM4, and COM6) can be used to communicate with
devices over BACnet. E2 supports BACnet devices that
communicate using MS/TP and IP.
6.4.1 BACnet Overview
BACnet is defined by three basic concepts:
• Object
tors, and other functional elements that make up a
BACnet device. The
specified by BACnet protocol. Analog Input object
and Analog Output object are two of the most commonly used objects. BACnet devices are defined on
the network as

common properties include
flags. Optional properties for objects such as analog
input include minimum and maximum range, high
and low limits, etc.
• Services –
BACnet protocol defines “services”. These include
object access services, alarm and event services,
file access services, and a few more. Object access
services are the most commonly used since these
provide the fundamental “read/write” access to
object properties.
Data inside a BACnet device is organized as a series of
objects. Each objec
There is always at least one object in a device – it is used
to represent the device itself. This is called the Device
Object. The other objects represent the device’s data.

6.4.2 BACnet Communication
BACnet supports MS/TP or IP based communication.
6.4.2.1 Master Slave Token Passing
Master Slave Token Passing or MS/TP is the protocol
used over RS-485 for BACnet. Each device on the link is
considered the “master” when it has the token. If it does
not have immediate need to use the token, it is required to
pass the token along to the next device. All devices on the
link that do not currently have the token are regarded as
slaves, and are expected to listen to any messages the current master may have for it. Because some devices take
rns being master, the link is effectively peer to peer (not
tu
all MS/TP devices can be master).
It is possible for a device to be a constant slave, though
is uncommon, because in this case a device cannot send
it
such request as I-Am, notifications, etc.
MS/TP devices differentiate themselves with a MAC
address. MAC addresses

It should be noted that MS/TP BACnet devices do not
use their unique identifier for access
second identifier called a Device ID is used. This is
because BACnet traffic can be routed across IP or MS/TP
(i.e., the physical layer is different). The Device ID has a
much larger addressable range.

6.4.2.2 BACnet IP (Internet Protocol)
The E2 also supports connecting to devices through IP
(Internet Protocol). The device ID is used to identify the
devices.
6.4.2.3 Discovery
BACnet supports discovery of the devices on a network and interrogation of the devices so they report what
data objects they contain and what properties ea
supports.

6.4.2.4 Client-Server
To describe which role the device plays during communication we will use the term: client-s
is the side that actively initiates the request. The server is
the side that passively responds to the client reply. BACnet
devices can act both as client and server.
Most simple MS/TP and IP devices are passive servers. They wait passively for a system
and only then do the devices respond. The E2 will mostly
be an active client (although it does have to support some
server aspects).

7.2 Hardware Specifications
Standard industry-accepted practices for wiring of
Ethernet networks are expected. E2 controllers use a star
topology, identical to PC deployment. This includes a
unique “point-to-point” run from a switch or hub to the
controller (see Table 7-1 for hub part numbers for order-
ing). This is done with Category5 (or better) cable. Maximum distance for a run of 10BaseT is 328 feet (100
ers) (11.5 dB loss max).

TCP/IP
E2 controller versions 2.10 and later communicate

8.1 Overview
Echelon is an optional, two-conductor network that interconnects E2s and other associated devices, such as CC-100
case controllers, TD3 temperature displays, and ESR8 evaporator stepper regulator boards. All Echelon devices are wired
together using the daisy-chain method of network structuring. If an Echelon network-enabled E2 is required, it must be
specifically ordered from Emerson Retail Solutions as an Echelon-enabled E2, and equipped with an Echelon plug-in
card. See Section 4.3.1, Echel

8.4.1 Using a Termination Block (P/N 535-2715) to Terminate a Daisy Chain
Some Echelon Network devices, notably TD3s, have
no on-board means of terminating. For some other
devices, it is inconvenient to use the jumpers supplied for
termination (the CC-100/CS-100 case controllers, for
example, require the enclosure to be removed to set the
jumper).
To remedy these problems, Emerson Retail Solutions
ies termination blocks that can be wired to the end of
suppl
an Echelon cable segment. This termination block uses the
same three-pin connector as all other Echelon devices.
Wire the two signal wires to the outside terminals, and
connect the shield to the middle terminal (see Figure 8-4).

9 Input and Output Setup
9.1 The 16AI, 8IO, and MultiFlex Inputs
9.1.1 Connecting Sensors to Input Boards
There are five I/O Network boards that may accept
inputs: the MultiFlex, the 16AI, the ARTC, and the 8IO
Combination Input/Output Board. Wiring an input to these
boards requires three steps:
1. Connect the sensor’s signal wires to the two terminals of an input point.
2. Set the input type dip switch that corresponds to
the point
3. If necessary, connect t
to one of the 5V or 12V power terminals.
9.1.1.1 Wiring
MultiFlex Boards
An input point connector on a MultiFlex, 16AI, and
16AIe board consists of two terminals, as shown in Figure
9-1. One of these terminals, labeled
nal from the sensor, while the other, labeled “0v” is where
’s ground and/or cable shield wire is connected.

On the ARTC board, the input and output points are
predefined and are
labeled accordingly.
9.1.1.2 Sensor Wiring Types
Specific wiring types are required for each type of sen-
sor used with E2.
All Analog Temperature Sensors and Air Flow Sensors
Temperature and air flow sensors are to be wired with
shielded, 2 conductor, at least 22 GA wire (Belden # 8761
or equivalent).
All Pressure Transducers, Humidity Sensors, and
Refrigeration Transducers
Pressure and refrigeration transducers and humidity
sensors are to be wired with shielded, 3 conductor, at least
22 GA wire (Belden #8771 or equivalent).
Dewpoint and Light Level Sensors
These sensors are to be wired with shielded, 4 conductor at least 22 GA wire (Belden # 8729 or equivalent).
9.1.1.3 Input Type Dip Switches
An input type dip switch must be set for each input
point. Input type dip switches are located in the switch
banks labeled S1 and S2 on the MultiFlex, 16AI, and
switch bank S4 on the 8IO.
The input type dip switch tells the input board whether
the sensor connected to the point requires a DC sup-
or not
ply voltage in order to operate. If the sensor requires DC
ltage, the dip switch should be set to the DOWN posi-
vo
tion. If the sensor does not require power, or if it uses AC
wer, the dip switch should be set to the UP position. Dip
po
switches for unused points should be set to the UP position.
The dip switch positions for each specific s
is shown in Figure 9-2.
