AZ 3 MiniLink PD 5 Technical Guide 3

General

The ASM02454 MiniLink PD 5 is a RS-485 communications device that is used to integrate multiple local RS-485 commu-nication loops into a RS-485 network communications system See Figure 1 page 4 for dimensions

The MiniLink PD 5 is required on the Auto-Zone 3 (AZ 3) Control System to separate local loops Up to 60 MiniLink loops can be on a system

Local loop terminals on the MiniLink PD 5 are designed to connect to controllers that are daisy-chained together on its local RS-485 communications loop

Network loop terminals on the MiniLink PD 5 are used to daisy-chain multiple MiniLinks back to a CommLink 5 to form a network RS-485 communications loop This provides for a fully networked RS-485 communications system

The MiniLink PD 5 is required for VAV systems to allow infor-mation to be shared between the AZ 3 VAV unit controller and the AZ 3 VAVZone BACnetreg Controllers It is also required for zoning systems to facilitate voting of the zones to determine the HVAC unitrsquos heating and cooling mode of operation and provides tenant-logging capabilities

MiniLink PD 5

Features

The MiniLink PD 5 utilizes token passing communication ar-chitecture The MiniLink PD 5 is designed to serve as the local communications loop master This means that it is responsible for sending a token to all the controllers on the local communi-cations loop

Network communications are RS-485 type operating at 19200 or 115200 baud Local communications are also RS-485 type and operate at 9600 or 57600 baud

The MiniLink PD 5 is factory default set to high speed Dip switches can be changed to low speed if required for your ap-plication See Page 7

CV Single Loop System

The most basic of the Auto-Zone 3 systems is the CV Single Loop System It consists of one or more Constant Volume (CV) Make-up Air Units (MUA) andor Single Zone VAV (SZVAV) units each having their own AZ 3 Controller and associated expansion module(s)

The communications loop can have up to 59 controllers daisy-chained to-gether back to a MiniLink PD This is called a Local Loop The MiniLink provides for alarm polling of all controllers and also has the capability of broadcasting select sensor values to all controllers on the local loop This can be useful for example if you want to have one Outdoor Air Temperature Sensor to be used by all the controllers All communication wiring must be plenum-rated minimum 18-gauge 2-conductor twisted pair with shield cable AAON can supply communication wire that meets this specifi cation and is color coded for the network or local loop or if desired Belden 82760 or its equivalent wire may also be used

The CommLink 5 communications interface wires to the MiniLinkrsquos Network communication terminals This is called the Network Loop The CommLink 5 also connects via a USB cable to any Windowsreg computer with Prism 2 software installed for confi guring and monitoring of the system Prism 2 is a Windowsreg based graphical interface designed by AAON An optional IP Module is also available to provide IntranetInternet connectivity to the control system See Figure 5 on page 10 for a Typical CV Single Loop System Layout

CV Multiple Loop System

If you have more than 59 CV MUA andor SZVAV Units or other controllers such as the GPC-XP on your building project you will need to use a CV Multiple Loop System It is very similar to the CV Single Loop System except it has more than one local communications loop This system allows for up to 60 of these local loops to be tied together

Each local communications loop can have up to 59 controllers daisy-chained together back to a MiniLink PD This is called a Local Loop The MiniLink provides for alarm polling of all controllers and also has the capability of broadcasting select sensor values to all controllers on the control system This can be useful for example if you want to have one Outdoor Air Temperature Sensor to be used by all the controllers All communication wiring must be plenum-rated minimum 18-gauge 2-conductor twisted pair with shield cable AAON can supply com-munication wire that meets this specifi cation and is color coded for the network or local loop or if desired Belden 82760 or its equivalent wire may also be used

The CommLink 5 communications interface is daisy-chained to one MiniLinkrsquos Network communication terminals and from it to all the other MiniLinkrsquos Network communication terminals This is called the Network Loop The CommLink 5 also connects via a USB cable to any Windowsreg computer with Prism 2 software installed for confi guring and monitoring of the system Prism 2 is a Windowsreg based graphical interface designed by AAON An optional IP Module is also available to provide IntranetInternet connectivity to the control system See Figure 6 on page 10 for a Typical CV Multiple Loop System Layout

VAVZone Single Loop System

If you have a single HVAC unit that will be using VAV terminal units or are using a zoning system and have VAVZones on your system you should select the VAVZone Single Loop System On a Variable Volume Variable Temperature Zoning System up to 16 VAVZone BACnetreg Controllers can be voting zones and additional zone controllers can be non-voting zones For VAV systems you can have up to 58 total VAVZone BACnetreg controllers in addition to the HVAC unit controller that serves those VAV boxes

The communications loop can have up to 59 controllers daisy-chained to-gether back to a MiniLink PD This is called a Local Loop The MiniLink provides for alarm polling of all controllers and also has the capability of broadcasting select sensor values to all controllers on the local oop This can be useful for example if you want to have one Outdoor Air Temperature Sensor to be used by all the controllers All communication wiring must be plenum-rated minimum 18-gauge 2-conductor twisted pair with shield cable AAON can supply communication wire that meets this specifi cation and is color coded for the network or local loop or if desired Belden 82760 or its equivalent wire may also be used

The CommLink 5 communications interface wires to the MiniLinkrsquos Network communication terminals This is called the Network Loop The CommLink 5 also connects via a USB cable to any Windowsreg computer with Prism 2 software installed for confi guring and monitoring of the system Prism 2 is a Windowsreg based graphical interface designed by AAON An optional IP Module is also available to provide IntranetInternet connectivity to the control system See Figure 7 on page 11 for a Typical VAVZone Single Loop System Layout

VAVZone Multiple Loop System

If you have multiple HVAC units that will be using VAV Terminal Units or will be using a Zoning System and donrsquot have any CV units you should select the VAVZone Multiple Loop System On a Zoning System each local loop allows up to 16 VAVZone BACnetreg Controllers to be vot-ing zones and additional controllers to be non-voting zones For VAV systems you can have up to 58 total VAVZone BACnetreg controllers in addition to the HVAC unit controller that serves those VAV boxes This system allows for up to 60 of these local loops to be tied together

General

The ASM02454 MiniLink PD 5 is a RS-485 communications device that is used to integrate multiple local RS-485 commu-nication loops into a RS-485 network communications system See Figure 1 page 4 for dimensions

The MiniLink PD 5 is required on the Auto-Zone 3 (AZ 3) Control System to separate local loops Up to 60 MiniLink loops can be on a system

Local loop terminals on the MiniLink PD 5 are designed to connect to controllers that are daisy-chained together on its local RS-485 communications loop

Network loop terminals on the MiniLink PD 5 are used to daisy-chain multiple MiniLinks back to a CommLink 5 to form a network RS-485 communications loop This provides for a fully networked RS-485 communications system

The MiniLink PD 5 is required for VAV systems to allow infor-mation to be shared between the AZ 3 VAV unit controller and the AZ 3 VAVZone BACnetreg Controllers It is also required for zoning systems to facilitate voting of the zones to determine the HVAC unitrsquos heating and cooling mode of operation and provides tenant-logging capabilities

MiniLink PD 5

Features

The MiniLink PD 5 utilizes token passing communication ar-chitecture The MiniLink PD 5 is designed to serve as the local communications loop master This means that it is responsible for sending a token to all the controllers on the local communi-cations loop

Network communications are RS-485 type operating at 19200 or 115200 baud Local communications are also RS-485 type and operate at 9600 or 57600 baud

The MiniLink PD 5 is factory default set to high speed Dip switches can be changed to low speed if required for your ap-plication See Page 7

CV Single Loop System

The most basic of the Auto-Zone 3 systems is the CV Single Loop System It consists of one or more Constant Volume (CV) Make-up Air Units (MUA) andor Single Zone VAV (SZVAV) units each having their own AZ 3 Controller and associated expansion module(s)

The communications loop can have up to 59 controllers daisy-chained to-gether back to a MiniLink PD This is called a Local Loop The MiniLink provides for alarm polling of all controllers and also has the capability of broadcasting select sensor values to all controllers on the local loop This can be useful for example if you want to have one Outdoor Air Temperature Sensor to be used by all the controllers All communication wiring must be plenum-rated minimum 18-gauge 2-conductor twisted pair with shield cable AAON can supply communication wire that meets this specifi cation and is color coded for the network or local loop or if desired Belden 82760 or its equivalent wire may also be used

The CommLink 5 communications interface wires to the MiniLinkrsquos Network communication terminals This is called the Network Loop The CommLink 5 also connects via a USB cable to any Windowsreg computer with Prism 2 software installed for confi guring and monitoring of the system Prism 2 is a Windowsreg based graphical interface designed by AAON An optional IP Module is also available to provide IntranetInternet connectivity to the control system See Figure 5 on page 10 for a Typical CV Single Loop System Layout

CV Multiple Loop System

If you have more than 59 CV MUA andor SZVAV Units or other controllers such as the GPC-XP on your building project you will need to use a CV Multiple Loop System It is very similar to the CV Single Loop System except it has more than one local communications loop This system allows for up to 60 of these local loops to be tied together

Each local communications loop can have up to 59 controllers daisy-chained together back to a MiniLink PD This is called a Local Loop The MiniLink provides for alarm polling of all controllers and also has the capability of broadcasting select sensor values to all controllers on the control system This can be useful for example if you want to have one Outdoor Air Temperature Sensor to be used by all the controllers All communication wiring must be plenum-rated minimum 18-gauge 2-conductor twisted pair with shield cable AAON can supply com-munication wire that meets this specifi cation and is color coded for the network or local loop or if desired Belden 82760 or its equivalent wire may also be used

The CommLink 5 communications interface is daisy-chained to one MiniLinkrsquos Network communication terminals and from it to all the other MiniLinkrsquos Network communication terminals This is called the Network Loop The CommLink 5 also connects via a USB cable to any Windowsreg computer with Prism 2 software installed for confi guring and monitoring of the system Prism 2 is a Windowsreg based graphical interface designed by AAON An optional IP Module is also available to provide IntranetInternet connectivity to the control system See Figure 6 on page 10 for a Typical CV Multiple Loop System Layout

VAVZone Single Loop System

If you have a single HVAC unit that will be using VAV terminal units or are using a zoning system and have VAVZones on your system you should select the VAVZone Single Loop System On a Variable Volume Variable Temperature Zoning System up to 16 VAVZone BACnetreg Controllers can be voting zones and additional zone controllers can be non-voting zones For VAV systems you can have up to 58 total VAVZone BACnetreg controllers in addition to the HVAC unit controller that serves those VAV boxes

The communications loop can have up to 59 controllers daisy-chained to-gether back to a MiniLink PD This is called a Local Loop The MiniLink provides for alarm polling of all controllers and also has the capability of broadcasting select sensor values to all controllers on the local oop This can be useful for example if you want to have one Outdoor Air Temperature Sensor to be used by all the controllers All communication wiring must be plenum-rated minimum 18-gauge 2-conductor twisted pair with shield cable AAON can supply communication wire that meets this specifi cation and is color coded for the network or local loop or if desired Belden 82760 or its equivalent wire may also be used

VAVZone Multiple Loop System

If you have multiple HVAC units that will be using VAV Terminal Units or will be using a Zoning System and donrsquot have any CV units you should select the VAVZone Multiple Loop System On a Zoning System each local loop allows up to 16 VAVZone BACnetreg Controllers to be vot-ing zones and additional controllers to be non-voting zones For VAV systems you can have up to 58 total VAVZone BACnetreg controllers in addition to the HVAC unit controller that serves those VAV boxes This system allows for up to 60 of these local loops to be tied together

Each local communications loop can have up to 59 controllers daisy-chained together back to a MiniLink PD This is called a Local Loop The MiniLink provides for alarm polling of all controllers and also has the capability of broadcasting select sensor values to all controllers on the control system This can be useful for example if you want to have one Outdoor Air Temperature Sensor to be used by all the controllers All communication wiring must be plenum-rated minimum 18-gauge 2-conductor twisted pair with shield cable AAON can supply com-munication wire that meets this specifi cation and is color coded for the network or local loop or if desired Belden 82760 or its equivalent wire may also be used

The CommLink 5 communications interface is daisy-chained to one MiniLinkrsquos Network communication terminals and from it to all the other MiniLinkrsquos Network communication terminals This is called the Network Loop The CommLink 5 also connects via a USB cable to any Windowsreg computer with Prism 2 software installed for confi guring and monitoring of the system Prism 2 is a Windowsreg based graphical interface designed by AAON An optional IP Module is also available to provide IntranetInternet connectivity to the control system See Figure 6 on page 10 for a Typical CV Multiple Loop System Layout

VAVZone Single Loop System

If you have a single HVAC unit that will be using VAV terminal units or are using a zoning system and have VAVZones on your system you should select the VAVZone Single Loop System On a Variable Volume Variable Temperature Zoning System up to 16 VAVZone BACnetreg Controllers can be voting zones and additional zone controllers can be non-voting zones For VAV systems you can have up to 58 total VAVZone BACnetreg controllers in addition to the HVAC unit controller that serves those VAV boxes

The communications loop can have up to 59 controllers daisy-chained to-gether back to a MiniLink PD This is called a Local Loop The MiniLink provides for alarm polling of all controllers and also has the capability of broadcasting select sensor values to all controllers on the local oop This can be useful for example if you want to have one Outdoor Air Temperature Sensor to be used by all the controllers All communication wiring must be plenum-rated minimum 18-gauge 2-conductor twisted pair with shield cable AAON can supply communication wire that meets this specifi cation and is color coded for the network or local loop or if desired Belden 82760 or its equivalent wire may also be used

other MiniLinkrsquos Network communication terminals This is called the Network Loop The CommLink 5 also connects via a USB cable to any Windowsreg computer with Prism 2 software installed for confi guring and monitoring of the system Prism 2 is a Windowsreg based graphical interface designed by AAON An optional IP Module is also available to provide IntranetInternet connectivity to the control system See Figure 9 on page 11 for a Typical VAVZone Multiple Loop System Layout

VAVZone amp CV Single Loop System

If you have a single HVAC unit with VAV Terminal Units or a Zoning system also have CV MUA andor SZVAV units and other controllers such as the GPC-XP controller andor your total number of controllers is less than 58 you should select the VAVZone amp CV Single Loop System The local loop provides for up to 58 previously mentioned controllers in addition to the HVAC unit controller that is connected to the VAVZone BACnetreg Controllers On the local loop up to 16 VAVZone BACnetreg

Controllers can be voting zones and additional controllers can be made up of non-voting zones or the other previously mentioned controllers For VAV systems you can also have up to 58 total VAVZone BACnetreg Controllers andor previously mentioned controllers in addition to the HVAC unit controller that serves those VAV boxes

The communications loop can have up to 59 controllers daisy-chained together back to a MiniLink PD This is called a Local Loop The MiniLink provides for alarm polling of all controllers and also has the capability of broadcasting select sensor values to all controllers on the local loop This can be useful for example if you want to have one Outdoor Air Temperature Sensor to be used by all the controllers All communication wiring must be plenum-rated minimum 18-gauge 2-conductor twisted pair with shield cable AAON can supply com-munication wire that meets this specifi cation and is color coded for the network or local loop or if desired Belden 82760 or its equivalent wire may also be used
