The following steps will get you up and running in no time: 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 1. Familiarize yourself with the PT-Link II components (Figure 1). DIP switches. 2. Connect your PT-Link II to the Controller(s) on your system (up • Set the BACnet® MS/TP MAC Address using the PT-Link A to four) and connect your PT-Link II to the BACnet® Network Bank DIP switches. The BACnet® MS/TP MAC Address (Figure 2). NOTE: Controllers must be addressed as MUST be set between 1 and 127. 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.

The DIP Switches allow you to set the protocol between BACnet® MS/ FFP-485 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 DIP shown in Figure 3. Switch Bank A 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 DIP Switch Using B1 – B4 to Set Baud Rate Bank B Baud B1 B2 B3 B4 9600 ON ON ON ON 19200 OFF OFF OFF ON 38400 ON ON OFF ON Figure 3: DIP Switches 57600 OFF OFF ON ON 76800 ON OFF ON ON CAUTION: DIP Switch 8 in Bank A must always remain OFF Table 2: Baud Rate Settings for proper operation.
® 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.

1.) Connect the PT-Link II directly to your computer by using a standard CAT5 or crossover cable (by others) as shown. See Figure 4 for details. 2.) Locate a CAT5 cable and plug one end into your computer’s Ethernet port. Plug the other end of the Cable into the Ethernet port on the PT-Link II. 3.) Power up the PT-Link II by plugging in the power cable. The PT-Link II may take up to three minutes to power up completely. Once the PT-Link II is powered up, you should notice that the RUN LED is blinking continuously on the ProtoCessor Board. See Figure 18, page 21 for a diagram showing the location of the ProtoCessor RUN LED.

PT-LInk II BACnet4 Technical Guide 19 Zone 5. TROUBLESHOOTING Zone 5.2 Troubleshooting LEDs
5.2.1 PT-Link II Board LEDs The 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 LED When 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 LED When 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 1 When 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 2 Figure 17: PT-Link II BACNET® LED Locations When 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 WATCH DOG LED that the “PWR” LED is lit up on the ProtoCessor Module. The “W-DOG” LED is used for troubleshooting by AAON Controls Support. The “W-DOG” LED should always be on solid.

If both LEDs When the PT-Link II is first powered up, the PWR“ ” green LED should are blinking, then communication is working properly. If not, check light up and stay on continuously. If the LED doesn’t light up, check the protocol network wiring and the baud rate in the configuration file. that the ProtoCessor is installed correctly and firmly connected to the Base Board. RUN LED Upon 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 LED The “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 LED The “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 LED The “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.

For instructions on downloading BACnet Explorer, perform a search in your internet browser for the latest Sierra Monitor’s BACnet® Examples: Explorer Start-up Guide. For purchasing information, go to the BACnet® Explorer page on 1.) Properties of the controller address as 1 will range the Sierra Monitor website (www.sierramonitor.com/connect/all- from 0 to 499. protocol-gateway-products/bacnet-explorer) and click on the “BUY 2.) Properties of the controller address as 2 will range NOW” tab. 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.
