2.1 Quick Start Guide

Figure 1: PT-Link II BACnet® Dimensions and Components

The following steps will get you up and running in no time:

1. Familiarize yourself with the PT-Link II components (Figure 1).

2. Connect your PT-Link II to the Controller(s) on your system (up to four) and connect your PT-Link II to the BACnet® Network (Figure 2). NOTE: Controllers must be addressed as 1, 2, 3 & 4.

3. Obtain the following from your Building Automation System Integrator: the BACnet® MAC address (System Node ID) and the MS/TP network baud rate. Also, relay to your System Integrator that the BACnet® Device Instance Number for the PT-Link will be the MAC address + 50,000 (50,000 is the default Device Instance Number). If you want the Device Instance number to be anything other than 50,000, you will need to access the FS-GUI Toolbox. See Section 3.3.2, page 12.

4. Configure your PT Link DIP Switches. See Section 2.3, page 7.

• Set the BACnet® MS/TP baud rate via the B Bank set of DIP switches.

• Set the BACnet® MS/TP MAC Address using the PT-Link A Bank DIP switches. The BACnet® MS/TP MAC Address MUST be set between 1 and 127.

2.3 Configuring the PT-Link DIP Switches

The DIP Switches allow you to set the protocol between BACnet® MS/TP and BACnet® IP (AAON only supports BACnet® MS/TP appli-cations), set the BACnet® MS/TP baud rate, set the BACnet® MS/TP MAC address, and set the BACnet® MS/TP device instance. You can obtain the MAC address, Device Instance, and baud rate from your Building Automation System (BAS) Integrator. The DIP Switches are shown in Figure 3.

NOTE: You must cycle power after making changes to the DIP Switch Settings for the settings to take effect.

2.3.1 Set the BACnet® MS/TP Baud Rate

“B” bank DIP switches B1 – B4 is used to set the BACnet® MS/TP baud rate of the PT-Link. This matches the baud rate required by the Building

2.3.2 Set the BACnet MS/TP MAC Address

1. Only (1) MAC address is set for the PT-Link regardless of how many devices are connected to it.

2. Set the BACnet® MS/TP MAC addresses of the PT-Link to a value between 1 and 127 (MAC Master Addresses). This is so that the BMS Front End can find the PT-Link via the BACnet® auto discovery func-tion. MAC addresses from 128 to 255 cannot be auto discovered by the BMS Front End.

3. Set “A” bank DIP switches A1 – A7 to assign a MAC Address to the PT-Link for BACnet® MS/TP. Please refer to Section 9, page 82 for the complete range of MAC Addresses and DIP switch settings.

NOTE: The BACnet® Device’s Instance is generated by adding the MAC address to the Node Offset, which defaults to 50,000. If the Device Instance must be set to something other than in the range of 50,001 to 50,127, see Section 3.3.2, page 12 to change the Node Offset value.

CAUTION: DIP Switch 8 in Bank A must always remain OFF for proper operation.

3.1 Graphical User Interface

The PT-Link is configured using a Graphic User Interface (GUI) which is a password protected web browser-based interface that uses a combination of technologies and devices to provide a platform from which you can gather and process information. The GUI allows you to do the following:

• Change the BACnet® Device Instance to something other than 50,001 to 50,127

• Check the status and diagnostics of the PT-Link, such as network settings, connection information, node information, map descriptors, and error messages

• Monitor the PT-Link’s internal data and parameters

• Change or update the PT-Link’s internal data and parameters

• Restart the PT-Link

The following items are needed to be able to run the GUI:

• PC Requirements—a computer with a web browser that connects over the Ethernet on port 80*

*NOTE: Computer and network firewalls must be opened for Port 80 to allow the GUI to function.

• Software Requirements—Chrome 19.0 and higher, Firefox 13.0 and higher, Opera 11.0 and higher, Microsoft Edge, and Safari 4.1 and higher

Zone5. TROUBLESHOOTING


5.2.1 PT-Link II Board LEDsThe PT-Link II BACnet® is equipped with LEDs that can be used for troubleshooting. There are eight LEDs on the PT-Link board. See Figure 17 for the locations of the LEDs on the PT-Link board. The LED descrip-tions and functions are listed in the following paragraphs.

POWER LEDWhen the PT-Link II BACnet® is powered up, the “POWER” LED should light up and stay on continuously. If it does not light up, check to be sure that you have 24 VAC connected to the board, that the wir-ing connections are tight, and that they are wired for correct polarity. The 24 VAC power must be connected so that all ground wires remain common. If after making all these checks the “POWER” LED still does not light up, please contact AAON Controls Support at our Toll Free number—866-918-1100—for assistance.

LOOP LEDWhen power is applied to the PT-Link II BACnet®, the “LOOP” LED will also light up. The LED should flicker rapidly, indicating that the PT-Link is trying to communicate with the controllers on the loop. A “flicker” is defined as a brief moment when the LED turns off and back on. If the “LOOP” LED does not operate as indicated above, first power down the unit and then reapply power. If this does not work, please con-tact AAON Controls Support at our Toll Free number—866-918-1100—for assistance.

LED 1When power is first applied, “LED 1” will be off temporarily and then will blink one time for each controller it is communicating with. For example, if you have 4 controllers on the loop connected to the PT-Link, “LED 1” will blink 4 times. If the amount of blinks does not match the number of controllers connected to the loop, it indicates there is a com-munications problem. The best way to find out which board is not com-municating is to go to each controller and look at its “COMM” LED. The “COMM” LED should be solid and will flicker occasionally indicating communication with the PT-Link II BACnet®. If the “COMM” LED does not flicker, there is no communication with that controller.

LED 2When power is first applied, “LED 2” will be off temporarily and then will blink slowly indicating that the PT-Link baseboard is communicating with the ProtoCessor Module. If “LED 2” does not blink, check that the ProtoCessor Module is installed correctly on the PT-Link baseboard and that the “PWR” LED is lit up on the ProtoCessor Module.

PROTO LEDWhen the PT-Link II is first powered up, the “PROTO” LED should blink rapidly and may appear to be on solid. This LED verifies com-munication with the board and the ProtoCessor. If the LED doesn’t light up, check that the ProtoCessor is installed correctly and firmly connected to the Base Board. The “PWR” LED should also be lit on the ProtoCessor Module.

TIMER LEDThe “TIMER” LED is used for troubleshooting by AAON Controls Support. The “TIMER” LED should always be blinking steadily.

Figure 17: PT-Link II BACNET® LED Locations

WATCH DOG LEDThe “W-DOG” LED is used for troubleshooting by AAON Controls Support. The “W-DOG” LED should always be on solid.

HEARTBEAT LEDThe “H-BEAT” LED blinks to show the PT-Link II board software is running. If the LED doesn’t light up, and all other checks have been made, please contact AAON Controls Support at our Toll Free num-ber—866-918-1100—for assistance.

5.2.2 PT-Link Module LEDs

Refer to Figure 18 for LED locations.

PWR LEDWhen the PT-Link II is first powered up, the “PWR” green LED should light up and stay on continuously. If the LED doesn’t light up, check that the ProtoCessor is installed correctly and firmly connected to the Base Board.

RX & TX LEDsDuring normal operation, the “RX” LED will flash when a message is received on the field port of the ProtoCessor and the “TX” LED will flash when a message is sent on the field port of the ProtoCessor. The “TX” and “RX” LEDs work together to indicate that communication is being established with the desired protocol network. If both LEDs are blinking, then communication is working properly. If not, check the protocol network wiring and the baud rate in the configuration file.

RUN LEDUpon power up, the “RUN” LED should light up and stay solid for 15 seconds. It should then blink steadily, signifying normal operation. The ProtoCessor will be able to access RUINET once this LED starts flashing.

RUN2 LEDThe “RUN2” LED should blink steadily after power up, signifying normal operation. The Protocessor will be able to access RUINET once this LED starts flashing.

SYS ERR LEDThe “SYS ERR” LED will go on solid 15 seconds after power up and then shut off. A steady red light will indicate there is a system error on the ProtoCessor. If this occurs, immediately report the related “system error” shown in the error screen of the Remote User Interface to Field-Server Technologies for evaluation.

NODE OFFLINE LEDThe “NODE OFFLINE” amber LED will go on solid 15 seconds after power up and then shut off. A steady amber light indicates the ProtoCes-sor is not communicating with a device that it is polling.

NOTE: If all of these tests are made and the controller still doesn’t operate, please contact AAON Controls Support at our Toll Free number—866-918-1100—for assistance.

5.3 Troubleshooting the PT-Link Controller

5.3.1 Addressing AAON Devices in a BACnet® Network

Each PT-Link II BACnet® generates only one BACnet® device regardless of the number of AAON controls connected to it. This device will have all the properties of all the AAON controls con-nected. The instance of the device is equal to the unit address. The properties of each control can be differentiated by an offset of 500.

Examples:

1.) Properties of the controller address as 1 will range from 0 to 499.2.) Properties of the controller address as 2 will range from 500 to 999.3.) Properties of the controller address as 3 will range from 1000 to 1499.

To search for the instance of a specific property, follow the next formula:

Property Instance = ((Controller Address – 1) * 500) + Instance Number from table.

Example:

1.) The PT-Link II BACnet® has a Node ID equal to five.2.) Two VCM controllers connected and addressed to one and four.3.) Searching for the Outdoor Temperature of each controller.4.) Instance of the Outdoor Temperature in the VCM table equal to AI: 54.5.) Client will only see Device 5. 6.) Under Device 5 it will see AI: 54 for the Outdoor Temperature of the unit addressed as 1 and AI: 1554 for the Outdoor Temperature of the unit addressed as 4.

NOTE: To simplify the calculation, we recommend that the AAON controllers be addressed in sequential order from one to the last controller without any unused address(es) in between.

5.3.2 BACnet® Explorer for Validating PT-Link in the Field

Sierra Monitor Corporation offers a tool, BACnet® Explorer, that can be used to validate BACnet® MS/TP communications of the PT-Link in the field without having to have the BMS Integrator on site.

For instructions on downloading BACnet® Explorer, perform a search in your internet browser for the latest Sierra Monitor’s BACnet® Explorer Start-up Guide.

For purchasing information, go to the BACnet® Explorer page on the Sierra Monitor website (www.sierramonitor.com/connect/all-protocol-gateway-products/bacnet-explorer) and click on the “BUY NOW” tab.
