Overview
The Orion system components can be confi gured into several types
of systems. It is a good idea to become familiar with the different
types of systems and their architecture by reading the information in
this section and looking at the confi guration diagrams in the System
Confi gurations section of this manual. The information below is de-
signed to help you understand how the system components integrate
with each other and the available confi guration options.
System Types
Four different system confi gurations are available depending on
the type and number of controllers that you have on your system.
1. Stand Alone
(See
Figure 3, page 22 for Connection Diagram)
2. Interconnected
(See
Figure 4, page 23 for Connection Diagram)
3. Networked Single Loop
(See
Figures 5-9, pages 24-28 for Connection
Diagrams)
4. Networked Multiple Loop
(See
Figures 10-11, pages 29-30 for Connection
Diagrams)
5. Computer, CommLink 5, IP Module, USB-Link 2
(See
Figures 54-58, pages 76-80 for Connection
Diagrams)
System Type Definitions
Stand Alone
This system consists of a single VCM-X E-BUS Controller. Pro-
gramming and status monitoring are accomplished by one or more
of the following methods.
1. By using an operator interface. This can be a Modular
System Manager, a System Manager TS II, a Modular
Service Tool, or all 3 devices.
2. A computer interface can also be used in conjunction
with the other operator interfaces listed above, or
by itself. This requires a CommLink 5 or USB-Link 2
and a personal computer with the Prism 2 computer
front end software installed.
Interconnected
This system consists of a group of VCM-X E-BUS Controllers
interconnected with communication cable to allow programming
from one central location. Broadcasting between controllers is not
available. Programming and status monitoring are accomplished by
one or more of the following methods.
1. By using an operator interface. This can be a Modular
System Manager, a System Manager TS II, a Modular
Service Tool, or all 3 devices.
2. A computer interface can also be used in conjunction
with the other operator interfaces listed above, or by
itself. This requires a CommLink 5 or USB-Link 2 and a
personal computer with the Prism 2 computer front end
software installed.
Networked Single Loop
The Networked Single Loop system, as its name implies, consists of
a single communications loop. This loop utilizes a network device to
share information that is broadcast from one controller to all control-
lers on the loop. The system can consist of the following devices.
1. A series of VCM-X E-BUS Controllers that utilizes
a network device to share information that is broadcast
from one controller to all controllers on the loop.
2. A single VCM-X E-BUS Controller and a series of VAV/
Zone Controllers. These VAV/Zone Controllers can
either be of the Modular type or Non-modular type.
The Modular type use Power/Comm Boards and
prefabricated cables and the Non-Modular type utilize
terminals and 2 conductor twisted pair with shield wire.
A network device is used to share information which is
broadcast back and forth between all controllers on the
loop.
These systems require a network device in the form of either a
CommLink 5 communications interface or a MiniLink Polling De-
vice. Both network devices may also be used together. Programming
and status monitoring are accomplished by the following methods:
1. By using an operator interface. This can be a Modular
System Manager, a System Manager TS II, a Modular
Service Tool, or all 3 devices.
2. A computer interface can also be used in conjunction
with the other operator interfaces listed above, or
by itself. This requires a CommLink 5 or USB-Link 2
and a personal computer with the Prism 2 computer
front end software installed.
When using the MiniLink Polling Device alone, only the System
Manager, System Manager TS II, and Modular Service Tool can be
used to program and monitor the system. With the addition of the
CommLink 5, the Prism 2 computer front end software and a PC
can be used to program and monitor the system in addition to the
Modular Service Tool, Modular System Manager, and the System
Manager TS II.
