Running RUINET
Connecting To The PT-Link II
1.) In order to communicate and program the PT-Link II 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/software-new.html under PT-Link II Software
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.
2.) If RUINET is in the desktop directory (if it isn’t, locate its directory), double-click on RUINET, and the RUINET program should
run. Initially, you might see the screen below (Figure 9). Type <I> for
Specify IP Address and the message “Enter IP Address of the Field
Server to Connect to” will appear on the screen.
5.) On subsequent connections, a list of PT-Link II’s that have been
recently connected may appear under the message “Recently connected
to FieldServers.” Select the required PT-Link II by typing the Number
or Letter in the left hand column. (Figure 10).
Figure 10: RUINET PT-Link II Selection Menu
6.) Once connected, you will see the RUINET Main Menu (Figure
11). Unless you need to make changes to the confi g.csv fi le (see Steps
9-13 on page 10 & 11), you are now ready to send and receive fi les to
and from the PT-Link II .
Figure 9: RUINET PT-Link II Specify IP Address
3.) Type the IP Address of <192.168.1.24> and press <Enter>.
4.) If you have only one PT -Link II connected to the network, then RUINET will automatically connect to that particular PT -Link II ; otherwise,
a menu will appear to allow the selection of the desired PT-Link II .
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 green LED displayed directly above and to
the right of the Ethernet port. This LED should be on
if the 10 BaseT cable is good. Secondly, observe the
red LED displayed directly above and to the left of the
Ethernet port. 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.
NOTE: If you are installing a LON PT Link and the LON BAS
is using implicit addressing, no changes need to be made
to the confi g.csv fi le and you can skip to step 14.

PT-Link II LON® Technical Guide
Changing the Confi g.csv File
NOTE: The PT-Link II contains an external interface fi le other-
wise 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 12 & 13 below for screen details. Refer to
Appendix B, page 25 for details on uploading XIF fi les.
7.) Type the letter <U> to upload the Confi g fi le (Figure 12), then type
<U> again (Figure 13) for Upload.
WARNING: Only edit the confi g.csv fi le using Notepad. DO
NOT use Excel. Using Excel to edit the confi g.csv fi le will cor-
rupt its contents!
9.) Follow the directions under “Explicit and Implicit Addressing”
on pages 12 & 13 to make changes to the confi g.csv fi le.
10.) Once the changes are made to the confi g.csv fi le, click <File>
in the upper left and then click <Save>. Now close the fi le and
return to the RUINET Main Menu.

PT-Link II LON® Technical Guide
Implicit Addressing
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 II 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 II LON to other LonWorks nodes—the
PT-Link II LON is assigned its data transfer (binding) parameters by
the Network Management Tool.
NOTE: The PT-Link II 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.
Implicit Addressing Commissioning Using
LonMaker
1.) Ensure that the correct fi rmware and latest confi guration is
loaded on the PT-Link II LON.
NOTE: Each change in the PT -Link II LON requires re-commis-
sioning of the PT-Link II LON in LonMaker.
5.) Once Visio is open with the Network showing, drag a new
device onto the drawing from the toolbox.
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 II LON when asked to
do so, and the PT-Link II 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 II 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.
2.) Ensure that the PT-Link II 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

PT-Link II Interface
Explicit Addressing & Domain Table Setup
To use explicit addressing, the client needs to change the factory settings
contained in the PT-Link II 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 17 to “Explicit”
shown in Figure 18. You should also change the “Lon
works _Input” and “Lonworks_Outputs” from Update to
Polled.
Figure 17: PT-Link II LON Implicit Confi guration
PT-Link II LON® Technical Guide
Explicit Addressing
Figure 18: PT-Link II LON Explicit Confi guration
In addition, the PT -Link II 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 II LON parameters
as follows:
//==================================================
//
// Common Information
//
Bridge
System_Address ,Title
23 ,”:D48:S01:Wattmaster Explicit Lon v1.00d”
Figure 19: PT-Link II 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.

PT-Link II LON® Technical Guide
Troubleshooting the PT-Link Controller
PT-Link II Board LEDs
The PT-Link II LON® is equipped with LEDs that can be used for
troubleshooting. There are eight LEDs on the PT-Link II board. See
Figure 20 for the locations of the LEDs on the PT-Link II board. The
LED descriptions and functions are listed in the following paragraphs.
POWER LED
When the PT -Link II LON® 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 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 “POWER” 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 II LON
also light up. The LED should fl icker rapidly, indicating that the PT -Link
II 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.
®,
the “LOOP” LED will
LED 1
When power is fi rst 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
II , “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
communications problem. The best way to fi nd out which board is not
communicating is to go to each controller and look at its “COMM”
LED. The “COMM” LED should be solid and will fl icker occasionally
indicating communication with the PT -Link II LON
LED does not fl icker, there is no communication with that controller.
®
. If the “COMM”
LED 2
When power is fi rst applied, “LED 2” will be off temporarily and then
will blink slowly indicating that the PT-Link II 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
II baseboard and that the “PWR” LED is lit up on the ProtoCessor
Module.
PROTO LED
When the PT-Link II is fi rst powered up, the “PROTO” LED should
light up and blink continuously. This LED verifi es communication with
the board and the ProtoCessor. If the LED doesn’t light up, check that the
ProtoCessor is installed correctly and fi rmly connected to the Base Board.
The “PWR” LED should also be lit on the ProtoCessor Module.
Figure 20: PT-Link II LON® LED Locations
WATCH DOG LED
The “W-DOG” LED is used for troubleshooting by W attMaster Controls
Technical Support. The “W-DOG” LED should always be on solid.
HEARTBEAT LED
The “H-BEAT” LED blinks to show the PT-Link II board software is

Troubleshooting the PT-Link Controller
ProtoCessor Module LEDs
PWR LED
When the PT -Link II is fi rst powered up, the “PWR” LED should light
up and stay on continuously. See Figur e 21. If the LED doesn’t light up,
check that the ProtoCessor is installed correctly and fi rmly connected
to the Base Board.
GPI05 LED
The “GPI05” LED will light up when the Base Board and the ProtoCessor Module have established communications. See Figure 21. This can
take up to 3 minutes depending on the number of units connected to
the PT-Link II . If it fails to light up after 3 minutes, check that the
ProtoCessor is installed correctly and fi rmly to the Base Board.
LON LED
Once the unit is powered up, the “LON” LED will blink continuously
until the PT-Link II has been commissioned. Once commissioned, the
“LON” LED will remain off.
PT-Link II LON® Technical Guide
LA LED
Once the unit is powered up, the “LA” LED must be blinking constantly.
See Figure 21. If this LED is constantly on or off, the Module is not
working properly and needs to be replaced.
TX & RX LEDs
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. See Figure
21. If not, check the protocol network wiring and the baud rate in the
confi guration fi le.
D14 & D15 LEDs
The “D14” and “D15” LEDs work together to indicate that communication is being transmitted and received from the USB Port when
performing an update to the PT-Link II software.
If all of these tests are made and the controller still doesn’t operate,
please contact WattMaster Controls Technical Support at our Toll Free
number—866-918-1100—for assistance.

Using RUINET
Before continuing with the troubleshooting, make sure the PT-Link II
is connected correctly and the RUINET software is installed, running,
and functioning correctly.
Verifying Proper Communications
From the RUINET Main Screen, press <O> to go the Connection
Overview Screen. This screen supplies information on communication
between the PT -Link II and remote devices. A number of aspect screens
are available, and some of the aspect screens have more than one page.
Use the space bar to toggle between aspects and use the <PgUp> and
<PgDn> keys to toggle between pages of the same aspect. The Connec-
tion Overview and Settings Aspect Screen is shown in Figure 22.
The main purpose in this screen is to verify that messages and characters
are being transmitted and received. In addition, it shows the number
of communication errors. If the PT-Link II connection “03” is the
protocol connection, verify that is communicating appropriately. If it
is not, check that the PT-Link II LEDs are working properly, the unit
is wired correctly, and the PT-Link II is confi gured correctly. If the
number of errors is constantly increasing, move to the Error Scr een by
pressing the
Use the <PgUp> and <PgDn> keys to toggle between pages of the

Verifying Proper Values
To verify that the correct values for each unit are being communicated
to the PT-Link II , move to the Data Array Overview Screen. To get to
the screen, press
for screen details.
In the Data Array Overview Screen (Figure 23) you will be able to see
the data arrays of all the units connected to the PT-Link II denoted by
an array name “DA_XXX_IY”—Y being the address of the unit minus
one. The Address of the unit is determined by a set of dip switches.
To view the values being communicated from a specifi c unit, move to
the Data Array Detail Screen (Figure 24) of the unit by entering the
number under which it is listed. For example, for the unit listed in the
third position, enter
To understand what each value means, look at the Data Array Tables
for the desired unit type, VCM-X, SA, or VCM. You can change the
writable values from this screen by using the modify command. T o use
the modify command, press
and then enter the Offset you want to change followed by a space and
the new value.
Example: T o change the Cooling Supply Setpoint to 60 in the VCM, press
<M>, enter <58 60>, and then press <Enter>. This could be useful to
prove that the unit can take and keep the setpoints properly.

fi guration can be changed by uploading and editing the confi g.csv
fi le; therefore, the XIF fi le must be obtained by uploading it from the

6.) After connection has been verifi ed, you can
now exit to the RUINET Main Menu by pressing <ESC>.
7.) Type <U> – Upload Confi guration.
8.) Type
<O> to select other fi les.
9.) If prompted, press any key to continue.
The recommended procedure for obtaining the XIF fi le for the PT-Link
II LON is to upload it. Remember that this XIF fi le will change when-
ever the confi guration fi le has been changed and downloaded and the
PT-Link II LON restarted. The following are the steps to extract the
external interface fi le (XIF) from the PT-Link II LON:
1.) Start RUINET application.
2.) Select Fieldserver option <1> (this step may be skipped
when application auto-detects PT Link).
3.) From the RUINET Main Menu, type <A> – Data Array
Overview.
4.) You should see 2 array items that are labeled wattmstr dump and wattmstr-stats. Ignore these.
5.) You should see 2 additional arrays for the controller
connected.
Example: DA_C162_I0 and DA_C162_I0b.
5.1.) The “b” at the end of the Data Array Name indicates
that it is a mirror array. You can ignore these.
5.2) Verify that your controller is visible or the XIF will not
be generated.
10.) Type
<R> – Remote Filename.
11.) Type <fserver.xif>.
12. You should now see the name fserver.xif in the column to
the right.
13. Type
<U> to upload the XIF fi le.
14. Once fi nished, you will have an .xif fi le available in the
same directory as the RUINET executable fi le you were
running from.
WARNING: For easier confi guration, set the unit address to 1.
