ELECTROSTATIC DISCHARGE CAUTION
This integrated circuit can be damaged by ESD. Failure to observe proper handling and
installation procedures can cause damage. ESD damage can range from subtle
performance degradation to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric changes may cause the
device to not meet its published specifications.

1Hardware
Overview
Site Supervisor (P/N 860-1200) is a system that
combines energy management with the ability to monitor
various facility systems and provide alerts when there are
issues that need attention. This system provides HVAC
control, Refrigeration System Monitoring and Control, as
well as Lighting Control. In addition, the Site Supervisor
can monitor and report energy consumption and take
action to reduce the energy demand during peak periods.
This can have a direct impact on utility bills by reducing
total energy costs. Site Supervisor ensures that the HVAC
and lighting systems are on and off at the appropriate
times. This ability to monitor store conditions can
potentially minimize energy consumption.
1.1 Technical
Specifications
1.2 Housing Dimensions
and Mounting
The Site Supervisor is DIN Rail mounting compatible.
Snap the orange tabs to the down position to fasten. If not
using the DIN Rail mounting option, fasten to the
mounting surface using the openings in the mounting tabs.

2RS485I/ONet-
work Boards and
Peripherals
Site Supervisor has up to two RS485 network ports,
each of which may be configured as an I/O network or
MODBUS port.
2.1 The I/O Network
Most of the general purpose input and output
communications devices required by the Site Supervisor to
control refrigeration systems are connected via the I/O
Network. The I/O Network is a simple RS485 three-wire
connection that allows data interchange between input
boards, which read sensor values and digital closures,
output boards, which carry out commands from Site
Supervisor's control applications, and the Site Supervisor
itself. All boards and controllers manufactured by
Emerson Retail Solutions for communication with Site
Supervisor 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 Site
Supervisor to read data from the input boards and to send
commands to the analog and digital output boards. Some
unit controllers, such as CCB case controllers and
MultiFlex RCBs, also communicate with the Site
Supervisor via the I/O Network.
2.2 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 Site Supervisor. However,
separate from the various MultiFlex unit controller
models, Site Supervisor only recognizes four different
types of I/O boards: 16AI, 8RO, 4AO, and 8DO. All Site
Supervisor-compatible I/O boards communicate with Site
Supervisor as if they are one or more of these types of
boards.
2.2.1 MultiFlex Boards
The MultiFlex line of control system boards provides a
wide variety of input, output, and smart control solutions,
all of which are based on a single universal hardware
platform. The board design uses flash-uploadable
firmware and plug-in expansion boards to configure the
base platform board and apply it for use as an input board,
relay output board, analog output board, or a combination
I/O board.
2.2.1.1 MultiFlex 16 Input Board
The MultiFlex 16 input board offers sixteen
combination analog/digital input points for use by Retail
Solutions Site Supervisor, Einstein, and REFLECS control
systems. The MultiFlex 16 may be used in retrofits with
no additional hardware or software setup or upgrades.Site
Supervisor
The MultiFlex 16 is designed to be 100% compatible
with the previous generation of Retail Solutions input
boards (the 16AI), communicates with the site controller
via an RS485 connection to a REFLECS COM A&D
Network or an Site Supervisor I/O Network. Dip switches
on the board set the network ID (board number) and baud
rate.
The board also provides both +5VDC and +12VDC
output voltage points for use in powering transducers or
other input devices that require power.
The MultiFlex 16 has a Hand-held Terminal interface
Section 2.2.7, Hand-held Terminal (P/N 814-3110) that
may be used by technicians to view the input voltage and
engineering unit values for each input point without need
of a voltmeter or front panel controller display.

2-2 • Site Supervisor Controller User Guide 2.0 026-1800 Rev 3 02-AUG-2016
Table 2-1 shows the part number of the MultiFlex 16.
The MultiFlex 16 is designed with several features that
make it easy to install, wire, and configure. These main
user interface features are shown in Figure 2-1.
2.2.1.2 MultiFlex Combination Input/
Output Boards
There are several models of the MultiFlex board that
combine the functionalities of input boards, relay output
boards, digital output boards, and analog output boards.
The MultiFlex combination input/output boards are
designed to be replacements for the 8IO Combination
Input/Output Board, but the MultiFlex board provides
several new hardware options and software features.
The MultiFlex combination I/O boards consist of up
to 16 combination digital/analog inputs, and a
combination of relay outputs, digital outputs, and analog
outputs.
