General Information
The OE368-23-LON, PT-Link-LON, provides bi-directional communication between ONE of the following types of Orion controllers—
VCM-X, SA, VCM, MUA II, or VAV/CAV:
VCM-X Controller (SS1026, SS1030, SS1032,
SS1033, SS1034, Y200920); SA Controller (Y200921)
VCM Controller (SS1016, Y200409, Y200616, Y200822)
*MUA II Controller (Y200405); VAV/CAV Controller (Y200301)
*NOTE: Documentation is available for MUA II/VAV/CAV on
our Orion Controls website: www.orioncontrols.com/
literature-new.html
NOTE: The PT-Link-LON device can be used to connect to only
one Orion controller. If more than one Orion controller is
present in a system, each one will require a PT -Link-LON
device for integration with a LON protocol network.
To determine what controller you have, you must look at the label located on the controller EPROM. If the controller label does not match
any of the SS or Y numbers listed above, your controller will not work
with the PT-Link-LON
®
.
Data Sharing
The PT-Link-LON interface provides the following data sharing capabilities:
• Provides values from points on the Orion side of the
gateway to LON® devices as if the values were
originating from LON® objects.
• Allows LON
®
devices to modify point values on the
Orion controller side of the PT-Link-LON® by using
standard LON® write services.

Locate a CA T5 cable and plug one end into your computer’s Ethernet
port (use a crossover cable if connecting directly to the PT-Link).
If connecting directly, plug the other end of the Cable into the Ethernet
port on the PT -Link. If connecting through an Ethernet Hub, plug the
other end of the PC cable into the hub, and use a second CAT5 cable
to connect the PT-Link to the hub as well.
Power up the PT-Link by plugging in the power cable. The PT-Link
may take up to three minutes to power up completely. Once the PTLink is powered up, you should notice that the green “GPI05” LED
light on the ProtoCessor Board remains on continuously. See Figur e
19 on page 12 for a diagram showing the location of the ProtoCessor
“GPI05” LED.
Computer IP Address Set-up for
Windows 98, NT, and XP
In order for the PT -Link to communicate properly, it is imperative to
set the IP address of both the PT-Link as well as the computer to be
within the same netmask. You need to change the IP address on your
computer. The following instructions will explain how to confi gure
the IP address for Microsoft
NT and XP computers.

PT-Link-LON® Technical Guide
Confi guring the PT-Link Controller
Connecting To The PT-Link
In order to communicate and program the PT-Link you will need to
install RUINET software on your computer. If you do not have the
software, it is available for downloading at www.orioncontrols.com in
the software area of the web site. After installing the software, proceed
with the following instructions.
WARNING: Make sure to load RUINET onto your hard drive
and run the program from your hard drive. DO NOT under any
circumstances run RUINET from your cd drive.
If RUINET is in the desktop directory (if it isn’t, locate its directory),
double-click on RUINET , and the RUINET program should run. If you
have only one PT-Link connected to the network, then RUINET will
automatically connect to that particular PT -Link; otherwise, a menu will
appear to allow the selection of the desired PT-Link.
This menu will look similar to the one shown in Figure 9.
Note: If RUINET is unable to establish a connection, there
are a few simple procedures you can perform to try to
determine the problem. To verify your network cables,
observe the “Yellow” LED displayed below “Ethernet
Connection” on the PT-Link’s ProtoCessor Module.
This LED should be on if the 10 BaseT cable is good.
Secondly, observe the “Green” LED below “Ethernet
Connection”. This LED should be solid while RUINET
is running. If the LEDs are lit as expected, and RUINET
still does not receive replies, then the netmask is probably incorrect. If this does not help, then your Ethernet
setup on your PC is possibly not compatible. Ensure that
you have an Ethernet adapter installed in your software
confi guration and that it is confi gured to run the TCP/IP
protocol. If you are still unable to connect, please contact
WattMaster Controls, Inc.
Making Changes to the Confi guration
File (confi g.csv)
To make changes to the confi guration fi le on the PT-Link, use the pro-
cedures outlined that follow — Upload, Address, Poll, and Download
the Confi guration File.
Figure 9: RUINET PT-Link Selection Menu
Select the required PT-Link by typing the Number or Letter in the left
hand column. You should now have a menu that looks like Figure 10.
You are now ready to send and receive fi les to and from the PT-Link.
Upload Confi g.csv from the PT-Link
The PT-Link contains a confi guration fi le (confi g.csv) that includes
information such as addressing. This fi le can be uploaded from the
PT-Link for modifi cation if needed. The PT-Link also contains an
external interface fi le otherwise called an XIF fi le (fserver.xif). The
XIF fi le includes information such as SNVT names and LON network
information. This fi le can be uploaded for use with LON programming
software. When uploaded, these fi les can be located in the same directory
that the RUINET executable fi le is stored and run from. Be sure when
uploading that the correct fi le is specifi ed in the upload window. Refer
to Figures 11 & 12 for screen details. Refer to Appendix B for details
on uploading XIF fi les.

1.) Begin the upload by pressing “U.”
2.) When the upload is completed, open the uploaded fi le with
Microsoft® Notepad. This program is supplied with
Microsoft® Windows. Type “N” to open using Notepad.
Implicit Addressing Commissioning Using
LonMaker
1.) Ensure that the correct fi rmware and latest confi guration is
loaded on the PT-Link-LON.
NOTE: Each change in the PT-Link-LON requires re-commis-
sioning of the PT-Link-LON in LonMaker.
2.) Ensure that the PT-Link-LON and the LonMaker machine
are on the same network.
3.) Open the existing Network in LonMaker or create a new
Network.
4.) Click on “Create New Network” and follow the network
wizard, making the following selections:
Network Interface: Choose Network Attached
Management Mode: Choose Onnet unless you are
working offl ine
Registered Plug-ins required: None
5.) Once Visio is open with the Network showing, drag a new
device onto the drawing from the toolbox.
WARNING: Only edit the confi g.sys fi le using Notepad. Do
not use Excel. Using Excel to edit the confi g.sys fi le will corrupt
its contents!
Explicit and Implicit Addressing
Clients can address the PT-Link using explicit or implicit addressing.
Clients using explicit addressing obtain their data transfer parameters
directly from the PT -Link-LON confi guration fi le (confi g.csv). Implicit
addressing is used when a Network Management T ool such as LonMaker®
is used to connect a PT-Link-LON to other LonWorks nodes—the
PT-Link-LON is assigned its data transfer (binding) parameters by the
Network Management Tool.
NOTE: The PT-Link-LON is confi gured from the factory to use
implicit addressing.
Implicit Addressing — Network Manager assigns addresses for
communication and ensures (via address tables in the devices) that
communication connections are known.
Explicit Addressing — Device knows the address of the point in
the remote device and communicates directly without the assistance of
the Network Manager.
6.) Follow the Device Network, making the following
selections:
Enter Device Name: Choose commission device
Specify Device Template: Choose upload from device
Specify Device Channel: Choose Auto Detect
Specify Device Properties: Leave as is (Ping is optional)
Identify Device: Choose service pin
Device Application Image: Leave unchecked
Initial State: Leave as is
7.) Press the service pin on the PT-Link-LON when asked to
do so, and the PT-Link-LON will be commissioned.
8.) Drag a new function block onto the drawing from the
toolbox. Give the function block a name and ensure that it
is allocated to the PT-Link-LON device.
9.) Once the function block is on the drawing, you can drag
input and output variables onto the function block. When
you do this, LonMaker will show you the variables
avail able for binding. Click on the variables you require
(or use the select “all” option), and they will be
commissioned onto the function block.
10.) You are now ready to connect these variables to other
devices by dragging connections from the toolbox and
connecting the variables.

PT-Link Interface
Troubleshooting the PT-Link Controller
Explicit Addressing & Domain Table Setup
To use explicit addressing, the client needs to change the factory settings
contained in the PT-Link-LON’s confi guration fi le (confi g.csv). The
following are the steps to change the confi guration fi le from implicit to
explicit addressing:
1.) Upload and open the confi g.csv fi le.
2.) Locate the “Connections” section.
3.) Locate the “Lonworks_Server” column and change the
value from “Implicit” shown in Figure 13 to “Explicit”
shown in Figure 14. You should also change the “Lon
works _Input” and “Lonworks_Outputs” from Update to
Polled.
Figure 13: PT-Link-LON Implicit Confi guration
PT-Link-LON® Technical Guide
Figure 14: PT-Link-LON Explicit Confi guration
In addition, the PT-Link-LON must have its domain, subnet, and node
IDs set. This feature is enabled in the confi guration fi le by fi lling out
the Title and System_Address fi elds of the PT-Link-LON parameters
as follows:
//==================================================
//
// Common Information
//
Bridge
System_Address ,Title
23 ,”:D48:S01:Wattmaster Explicit Lon v1.00d”
Figure 15: PT-Link-LON Domain and Subnet Setting
The Title fi eld must start with “:D”, followed by the domain_id in
hexadecimal notation, followed by “:S”, followed by the subnet_id in
hexadecimal notation, and enclosed by “:”. The domain length is automatically determined by the number of digits in the [domain_id] fi eld.
With 2 hexadecimal digits constituting 1 byte, “:D123456:”, for example,
would have a length of 3.
Once the domain table has been set, the “:Dxx:Sxx:” part of the Title
fi eld will be removed.
Now the Title fi eld will be left with [Title continued…] which may be
the Node self documentation string or any title.
After the changes are done, do not forget to save the fi le, download
the new confi guration fi le, and restart the PT-Link-LON. Refer to the
Download Section that follows.

Troubleshooting the PT-Link Controller
PT-Link Board LEDs
The PT -Link-LON® is equipped with LEDs that can be used for troubleshooting. There are four LEDs on the PT -Link board. See Figur e 18 for
the locations of the LEDs on the PT-Link board. The LED descriptions
and functions are listed in the following paragraphs.
PWR LED
When the PT -Link-LON® is powered up, the “PWR” 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 wiring 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 “PWR” LED still does not light up,
please contact WattMaster Controls Technical Support at our Toll Free
number—866-918-1100—for assistance.
LOOP LED
When power is applied to the PT-Link-LON
also light up. The LED should fl icker rapidly, indicating that the PT -Link
is trying to communicate with the controllers on the loop. A “fl icker”
is defi ned as a brief moment when the LED turns off and back on. If the
“LOOP” LED does not operate as indicated above, fi rst power down
the unit and then reapply power. If this does not work, please contact
W attMaster Controls Technical Support at our Toll Free number—866918-1100—for assistance.
