Introduction to ThermoTrak II
ThermoTrak II is a hardware/software networking system for the operation of Thermotron chamber and
oven controllers. Its Microsoft Windows environment provides access to chamber networking,
programming, operating, data acquisition, and display functions from a single host computer. ThermoTrak
II can be configured to automatically e-mail reports of a number of chamber events to your personnel.
ThermoTrak II logs data from different Thermotron controllers, giving the operator a Windows
environment for most current Thermotron controllers. It is capable of logging data points every two
seconds for an indefinite period, limited only by hard drive space.
The ThermoTrak II chamber window can display the following:
•
All the real-time variables your controllers provide
•
Full-color graphs of the set points and process variables
NOTE: ThermoTrak II cannot be used to operate chambers with AST 7800 or AST 8800 controllers, or SE
modules.

Installing a ThermoTrak II Network
Section 2:
Installing a ThermoTrak II Network
Installing a ThermoTrak II network requires the following:
•
Good working knowledge of chamber, Thermotron controller, and computer interface configuration
(as described in the computer interface section of the chamber controller manual).
•
Ability to complete installation of network cabling, including braided shield termination, wire
preparation, and knowledge of diagnostic practices as needed. To simplify this process, the
networking kits listed in the tables later in this section are available from Thermotron Industries.
•
Ability to find a hardware or software revision level. Refer to “Thermotron hardware/software
supported” in Section 1 of this manual.
Using Ethernet with 3800, 8200, 8800, or 8825 controllers
All 3800, 8200, 8800, and 8825 controllers support standard Ethernet cabling.
•
To connect a chamber to a hub, use a standard straight-through Ethernet cable.
•
To connect a chamber directly to a PC, use a standard crossover Ethernet cable.
NOTE: The 3800 controller supports communication only at 10 Mbit. A 100-Mbit network that does not
scale down cannot communicate with the 3800.
Using an Ethernet-to-serial converter box
ThermoTrak II uses port number 8888 when sending commands to an Ethernet-to-serial conveter box. If
you are using an Ethernet-to-serial converter box to connect a chamber to a local area network (LAN), set
the converter’s port number to 8888.

2800/4800 computer interface board configuration
The following provides a convenient reference to assist you in configuring your Thermotron 2800/4800
computer interface board. For more information, refer to the 2800 or 4800 programmer/controller
computer interface manual.
CAUTION: The 2800/4800 computer interface board contains components that are sensitive to
electrostatic charges. When working with the 2800/4800 computer interface board, make sure you provide
a static-safe work environment.
R2 line termination resistor: When this card is used at the end of the network line, supply a 120-ohm
resistor at R2. NOTE: Most RS-485 buses require termination at both ends because of fast transition, high
data rates, or long cables. For more information on termination, refer to Step 3 of “RS-485/RS-422
Network Cabling” later in this section.
W1 setting: Place the jumper on the appropriate terminal, either RS-232 or RS-485. (The factory setting is
RS-232.) NOTE: Power must be removed from the 2800/4800 before repositioning the jumper.

Installing a ThermoTrak II Network
RS-485/RS-422 network cabling
The cable and connections used to network your chambers are sometimes overlooked, but are actually
very important to ensure reliable data transfer along with electromagnetic compatibility (EMC). The
following are Thermotron’s guidelines for connecting a chamber network:
1.
Use a high quality shielded (24 AWG) twisted pair cable. For chamber networking Thermotron
recommends using T-Net RS-485/422 network cable (Thermotron p/n 1084413; Belden p/n 9842).
2.
Use Thermotron’s T-Net network components to connect your chamber network. The T-Net
components provide you with a simple yet reliable way to network your chamber controllers. The
components available include various cable assemblies, bulkhead connectors, and the T-Net junction
box. The T-Net junction box is used to properly interface individual chambers and the main network
line. The junction box is specifically designed for use with the cable recommended in item 1 above.
The following general diagram illustrates the T-Net components available for chamber networking.
The T-Net junction box will provide the networked controller with voltage protection, along with
electromagnetic interference (EMI) filtering for each data line. The junction box as well as all T-Net
cabling will also provide your complete network with the proper shielding that is required for an
industrial network application.
For detailed information on features and installation instructions for the T-Net junction box, refer to
“T-Net Junction Box Installation” later in this section. For selection of the specific cable assemblies/
bulkhead connectors that you need for your application, refer to “Using the 7800/7825 as an RS-232
to RS-485 Converter” earlier in this section, or the T-Net configuration diagram on page 2-21.

Terminate both ends of the main network cable. Termination of both ends of the network is required
to prevent data transmission problems. All Thermotron controllers/computer interface devices have
provisions to allow network termination.
For example, Thermotron’s external RS-232 to RS-485 converter harness kit can be used to terminate
one end of the network. (For details, see “ThermoTrak Harness RS-232 to RS-485 Converter” earlier in
this section.) A 120-ohm resistor (provided) can be installed in the junction box. If a 7800/7825
controller is on the other end of the network, simply place jumper W3 into the IN position. Likewise, if
a 2800, 4800, or 6850 controller is on the end of the network, you must supply a termination resistor

on the computer interface board. (For setup of a 2800 or 4800, refer to “2800/4800 Computer
Interface Board Configuration” earlier in this section.)
By following these guidelines, your chamber network will have the following characteristics:
•
Maximum electromagnetic compatibility (EMC)
•
Maximum data rate of 115.2k baud
•
Maximum network cable length of 4,000 feet
•
Up to 32 stations on the multidrop bus
Chamber bulkhead selection and installation
Chamber bulkhead connectors provide a clean connection point between external and internal chamber
communication cables. The bulkhead plate, when installed properly, will provide the low-resistance chassis
ground connection that is required for the network cable’s braided shield. Self-tapping #8 machine screws
are provided to mount each bulkhead. To accommodate the new bulkhead screws, the existing mounting
th
holes in the chamber wall will need to be drilled out to 0.140-inch using a 9/64 drill bit. With the proper
bond between the bulkhead and the chamber wall, the low-resistance path to chassis ground is
accomplished. The noise coupled into the shield of the network cable now has an easy path to ground
instead of coupling into the data lines.
When selecting the bulkhead required for your application, refer to the appropriate configuration drawing
earlier in this section. These will provide you with the information needed to select the appropriate
bulkhead connectors for your chambers. The following bulkheads are available:
•
T-Net bulkhead RSALL (BH9): The replacement bulkhead for the SE chamber line. It is the same size as
the standard SE chamber bulkhead and provides both the RS-232 and RS-422/485 connectors. This
bulkhead uses #8 self-tapping machine screws to mount to the chamber wall. You must drill the
th
existing chamber wall holes out to 0.140-inch using a 9/64 drill bit. Also two new holes on the top
and bottom center portions of the plate require two additional holes to be placed in the chamber wall.
•
T-Net bulkhead 28-68XX (BH25): The standard bulkhead connector used on chambers equipped with
2800 or 6850 controllers. It uses a 25-pin female-to-female gender changer mounted on an aluminum
bulkhead plate. If your 2800 or 6850 chamber was purchased with the serial interface option, you
probably have this connector along with the internal stub cable that connects to the controller. Verify
that your bulkhead connector is mounted on an aluminum bulkhead plate.
•
T-Net bulkhead RS422/485 (BH9): Provides a DB-9 male-to-male gender changer mounted on an
aluminum bulkhead plate. This can be used on early model SE chambers that do not have the
standard two-by-five-inch serial interface bulkhead, or on chamber retrofit applications. The DB-9
male-to-male connector is only used for RS-422/RS-485.
•
T-Net bulkhead RS-232 (BH9): Provides a DB-9 female-to-female gender changer mounted on an
aluminum bulkhead plate. The DB-9 female-to-female connector is only used for RS-232. This
bulkhead is primarily used for retrofit applications.
When attaching your new T-Net bulkhead, be certain to take precautions before drilling any holes. Locate
the access point in an area that is clear of structural supports and/or chamber components. Also take
precautions to prevent metal shavings from settling into critical areas. This includes electrical or electronic
components and/or wiring.

T-Net junction box installation
The T-Net junction box (p/n 1078763) is recommended to provide a reliable interface between your network
cable and one chamber to be installed on the network. It is specifically designed for use with T-Net RS-485/422
network cable (Thermotron p/n 1084413; Belden p/n 9842). The T-Net junction box will provide your chamber
network with the following essential features:
•
Cable shield termination. The installed cable glands provide your system with optimum 360-degree
termination of the network cable’s braided shield. By terminating the braided shield using this method,
your system will have maximum electromagnetic compatibility (EMC). The cable glands also provide strain
relief for the network cable. Complete installation instructions are provided below.
•
Network screw terminal connectors, which provide reliable and simple network connection without the
use of special tools or soldering. Each screw terminal is labeled to minimize connection time (coincides with
the color code of the 9842 Belden Cable/Western Electric standard):
□ Terminal 1: white/blue stripe (TX+)
□ Terminal 2: blue/white stripe (TX-)
□ Terminal 3: white/orange stripe (RX+)
□ Terminal 4: orange/white stripe (RX-)
□ Terminal 5: drain wire
•
Internal circuitry that will provide the controller’s computer interface and the RS-485/RS-422 card with
overvoltage protection and electromagnetic interference (EMI) filtering for each data line.
•
A diecast aluminum alloy enclosure for improved EMI shielding, and external wall mounting flanges to
allow simple installation.
As shown below, TB3 on the junction box PCB is the terminal block connector used for the T-Net fly lead
connection. As discussed in “RS-485/RS-422 Network Cabling” earlier in this section, selection of the
appropriate fly leads, as well as all other necessary hardware, can be obtained from the T-Net configuration
drawing that corresponds to your particular controller type.
The T-Net fly leads and the recommended network cable use the same type of cable (9842 Belden, p/n
1084413). Cable preparation is required before connection to the junction box is made. The illustration below
shows the required cable preparation to ensure proper connection/shield termination with the junction box.

Adding and removing a chamber
To begin with, at least one chamber must be defined and configured as available to ThermoTrak II. Note
that you are not limited to only one network of chambers. For example, you can define a 9600 baud GPIB
network of chambers on COM 1, and also define a 19200 baud RS-485 network of chambers on COM 2.
ThermoTrak II can monitor and operate up to four multidrop networks at a time, each with a maximum of
15 instruments (GPIB) or 32 instruments (RS-485).
1.
The Available Chambers window is always open. If the window is hidden by other windows, open the
Windows menu and click Available Chambers.
2.
Right-click anywhere in the Available Chambers window and click Add Chamber. This will open the
Edit Chamber Configuration dialog box. From the Chamber Info tab you can define the parameters
required to communicate with the chamber.
3.
Select the chamber’s controller type. NOTE: If your
3800, 8200, or 8800 controller is set to emulate a
legacy instrument’s command set using the
controller’s command compatibility setting, choose
the legacy instrument as the Controller Type.
For example, if your 3800’s command compatibility
setting is 2800, set the ThermoTrak II Controller
Type to Thermotron 2800.
4.
Select the appropriate computer interface, baud
rate, port, and address settings. The parameters set
here must match the computer interface settings
at the chamber controller.
•
If the chamber is part of a network of
chambers, enter a unique address value for
that chamber in the Address field. The RS-232
interface does not support any protocol for
addressing, so you must use either RS-485 or
GPIB.
•
If you select the TCP/IP interface, enter the
appropriate IP address in the IP Address field
and a valid TCP port in the TCP Port field. The
computer and controller must be on the same
subnet. If you need assistance, contact your
system administrator.
If you are using an Ethernet-to-serial converter, the ThermoTrak II IP address and TCP port settings
must match those of the converter. For more information, see “Using an Ethernet-to-Serial
Converter Box” in Section 2 of this manual. NOTE: 3800, 8200, 8800, and 8825 controllers have
built-in Ethernet capabilities.

•
If ThermoTrak II can communicate with the chamber, you will see the chamber’s identification
string and a software version number displayed in the text fields.
•
If there is a communication problem, a message will say “No response from chamber” in the ID
String box. This means either you have a faulty cable connection somewhere, or the
communication parameters are incorrect. You may change any of the parameters to retest the
settings as often as you like. If you need more information on hardware configuration, refer to
Section 2 of this manual.
NOTE: The more chambers you define on the network, the longer it takes ThermoTrak II to scan
the entire network one time.
8.
Once the chamber is properly defined, enter a descriptive name in the Chamber Description text
field. You also can enter a serial number in the Serial # field. NOTE: The 3800, 8200, 8800, and newer
versions of the 7800 controller software set the serial number automatically.
9.
To save the configuration and add the chamber to the Available Chambers window, click OK.
10. To remove a chamber from the list of available chambers, right-click the chamber name in the

ThermoTrak II User’s Guide
Creating and editing profiles
A profile is a description of a test. ThermoTrak II’s Profile Editor can be configured for use as either a form or a
spreadsheet. Both profile editor styles are illustrated on the following page. To change the profile editor style,
open the Options menu, click General Options, and select Form or Spreadsheet in the Profile Editor Style
field.
Once a profile is saved to disk, you can associate that profile with any chamber available to ThermoTrak II. The
software will appropriately translate your profile to the specific controller you assign it to. For example, if your
profile contains a three-channel profile, and a controller can use only two of the channels, ThermoTrak II assigns
only the two channels that apply to the controller’s configuration.
Keep in mind that some options are not compatible with all controllers. For example, a 2800/4800 controller
does not support the purge option, while an 8800 controller does. However, no harm will result from uploading
to a 2800/4800 controller a profile with the purge option enabled.
The same flexibility holds true for available auxiliary outputs. For example, a 4800 controller can use three
groups of four auxiliaries, while a 6850 controller can use two groups of eight auxiliaries.
•
If you program all three auxiliary groups of the 4800 in the profile, ThermoTrak II sends only the first two
groups to the 6850.
•
If you program all eight auxiliary outputs in the two groups of the 6850, ThermoTrak II sends only the first
four outputs of each group to groups 1 and 2 of the 4800.
If a profile using guaranteed soak is transferred between ThermoTrak II and an older controller (2800/4800,
6850, or 7800), the profile is converted. If the profile is being loaded into ThermoTrak II from an older controller,
ThermoTrak II will compress each pair of ramp-and-soak intervals into one interval to make them compatible
with ThermoTrak II. If the profile is being saved to an older controller, ThermoTrak II will split each guaranteed
soak interval into two intervals: one ramp and one soak. For example, if you create a profile in ThermoTrak II
that is five intervals long and contains two guaranteed soak intervals, the profile will be seven intervals long
when sent to a 7800.
NOTE: The following procedure assumes you have a good working knowledge of each chamber and
Thermotron controller on your ThermoTrak II network. For more detailed explanations of the concepts involved
in creating profiles, refer to your chamber controller manual.

•
In an interval with guaranteed soak (GSoak) enabled,
ThermoTrak II will immediately set the set point equal
to the interval’s final value and then wait until the
process variable is within the deviation band of the
final value. Once the process variable is within the
deviation band, the interval time will begin counting
down. For multiple channel programs, all non-zero
deviation bands must be satisfied before the interval
time will begin counting down.

Using ThermoTrak II with Local Networks
•
ThermoTrak II User’s Guide
Normal indicates the interval is based on time, so you must enter a non-zero time for the interval.
During a timed interval, the controller increases its set point based on the time allotted to reach
the final process variable. During process variable pull-ups or pull-downs, this creates a smooth
ramp between the initial and final set points. During process variable soaks, the controller
maintains the process variables at constant levels for the duration of the timed interval.
7.
In the fields labeled Final Value (form) or FV (spreadsheet), enter the final values (set points) for this
interval.
8.
In the fields labeled Deviation (form) or Dev (spreadsheet), enter the deviation value based on the
following definitions:
9.
•
During GSoak (guaranteed soak) intervals, the interval time will begin counting down once all
process variables are within their deviation bands. NOTE: A GSoak interval may never begin if the
deviation settings are too narrow.
•
During Normal (timed) intervals this is the deviation alarm band: the allowable difference between
the process variable and the current set point. For example, a humidity system may have an alarm
band of ±5% relative humidity (RH). During the interval, the relative humidity of the chamber must
be within ±5% RH of the current humidity set point.
In the fields labeled Interval Time (form) or Time (spreadsheet), enter the assigned duration of the
interval (in hours:minutes:seconds format).
10. The fields labeled Next Interval and Loops (form) or Next and # Loops (spreadsheet) allow you to
include programmed looping in your profile.
•
Next Interval indicates the interval to transition to after completion of the current interval.
•
# Loops is the total number of times the programmed loop will be executed.
For programmed looping, the Next Interval value is valid only if it is less than or equal to the number
of the current interval, and if the # Loops value is greater than 1. The interval will actually loop back to
the target interval the # Loops value minus 1. The following rules apply to looping:
•
The target interval may be the target of another loop, but must not cross into another loop.
(When a loop is crossed, the target interval is between the beginning interval and the ending
interval of the loop).
•
Nested looping is legal. In nested looping, one loop starts and finishes inside another loop. Both
loops can have the same target interval.
•
The final value of the looping interval should be the same as the initial value of the target interval.

Using ThermoTrak II with Local Networks
ThermoTrak II User’s Guide
ThermoTrak II allocates enough memory from Windows to store 32,768 graph plot points per
chamber. If you start a profile that runs longer than the available graph memory, ThermoTrak II will
throw out the oldest plot point to make room for the new plot point.
For example, if you choose to log data every two seconds, ThermoTrak II will inform you that you have
18 hours of graph memory available. After running a 19-hour test you will only have data for the last
18 hours of the test, with the first hour’s data thrown out to make room for the last hour’s data.
NOTE: Regardless of the amount of graph memory available, any data log text file you created in
step 4 above will not throw out any values and is limited only by your available hard drive space.
8.
Next, click the Graph Settings tab. From here you
select the settings for the graph functions:
•
The X Axis represents an amount of time in
days:hours:minutes format. For example, to see
a one-hour slice of the graph, select an X axis
minimum of 0:00:00 and a maximum of
0:01:00.
To allow the graph to move as new plot points
are sampled, click Scrolling. When scrolling is
enabled, instead of setting an X axis minimum
and maximum, you select a time span to view
in days:hours:minutes format.
To label the graph’s X axis with real times and
dates, clear the Use relative times check box.
9.
•
The Y Axis represents the minimum and
maximum process variables that will be
displayed on the graph. For example, a
temperature/altitude chamber might need a
scale of -80 to +800 to display low
temperatures and high torr values.
•
The Graph Settings tab also allows you to
name process variable, set point, throttle, internal, and monitor channels, and to assign different
line styles to them.
When you have all your graph and datalog parameters defined, click the OK button.

Aux Cool Frame Time: The time frame the controller uses to split up the ON and OFF times for
the auxiliary cooling output.
•
Aux Cool Duty Cycle: The percentage ON time the controller will apply to the above frame time.
•
Defrost at end of test: Allows you to program a defrost period at the end of a test. You should
enable this function if the thermal shock chamber does not have a few hours of down time
between tests, or if your location has high humidity.
•
Defrost every ‘N’ cycles: Allows you to program a defrost period every ‘n’ cycles, where ‘n’
represents a numerical value. Use this function if you are running long tests or if your location has
high humidity. To disable this function enter a zero.
•
Defrost Setpoint: The temperature the cold box will go to during the defrost period. Thermotron
uses a set point of +40.0°C. You may need to adjust the temperature to compensate for the
humidity levels in your area.
•
Defrost Timer Period: The number of minutes the cold box will remain in defrost mode.
Thermotron uses a time period of 30 minutes. The time will vary according to the humidity levels
in your area.
•
Wait while defrosting in: Allows you to select which box the shuttle should wait in during
defrost:

Using ThermoTrak II with Thermal Shock Controllers
Default: Shuttle will wait in whatever box it was in when defrost started.
Cold Box: Shuttle will always wait in the cold box during defrost.
Hot Box: Shuttle will always wait in the hot box during defrost.
Add Precondition Half-Cycle: Allows you to disable the pre-condition half-cycle that Thermotron
has always performed as part of a normal thermal shock test. If Yes is selected the thermal shock
chamber will act as it always has, with a pre-condition half-cycle performed at the start of the test
to allow the boxes to get to their test temperatures. If No is selected the chamber will not perform
this pre-condition half-cycle.

Creating and editing tests
The Test Editor is used to create and edit thermal shock chamber tests. Once a test is saved to disk, you
can associate that test with any thermal shock chamber available to ThermoTrak II. The software will
appropriately translate your test to the specific controller you assign it to. For example, if your test
contains three temperature zones, and a controller can use only two of the zones, ThermoTrak II assigns
only the two zones that apply to the controller’s configuration.
NOTE: The following procedure assumes you have a good working knowledge of each thermal shock
chamber on your ThermoTrak II network. For more detailed explanations of the concepts involved in
creating tests, refer to your chamber controller manual.
Using the test editor
1.
Double-click on a chamber name in the Available Chambers list. This will open the Chamber Status
window for that chamber. NOTE: If the Available Chambers window is hidden by other windows,
open the Windows menu and click Available Chambers.
•
To edit a profile already associated with the
selected chamber, click the Edit Profile button
on the Chamber Status window.
•
To create a new profile, either click the New
Program button on the toolbar, or open the
File menu and click New Program.
NOTE: Thermal shock tests are edited in form style
only.
2.
To start with, set the test temperature, offset
temperature, and pre-conditioning time for all
available boxes.
•
The Test Temperature is the required
temperature of each box. To produce the set
point ThermoTrak II adds the offset value or
pre-condition value to the test temperature.
ThermoTrak II operates the thermal shock
chamber to maintain the hot and cold box temperatures at the set point temperature.
•
The Offset Temperature is the number of degrees past the test temperature the hot or cold box
may deviate to achieve the test temperature at the product.
In double-duty chambers the offset value is added to the test temperature to produce a set
point for each box. The boxes will be at this set point temperature before the product enters
the box.
In vertical two-zone or horizontal three-zone chambers, the offset value is added to the test
temperature only when the basket is in the box. When the basket is not in the box, the precondition offset value is added to the test temperature.
The hot box offset value must be a positive number, and the cold box offset value must be a
negative number. (An offset value of 5 for the hot box and -5 for the cold box is a good place to
start.) If you do not want the set point to be different from the test temperature, enter zeros.
4-6
Thermotron Industries
ThermoTrak II User’s Guide
•
Using ThermoTrak II with Thermal Shock Controllers
In vertical two-zone or horizontal three-zone chambers, the pre-condition offset value is added to
the test temperature only when the basket is not in the box. NOTE: This field does not appear
when product temperature control (PTC) is enabled.
NOTE: Check the specifications listed in your chamber manual for acceptable ranges for temperature
and other process variables.
3.
Set the Soak Time (in minutes and seconds) and Auxiliaries for all available boxes. The soak time is
the total time in minutes and seconds on the “soak timer” for each box. See Soak Method below for
information on how the soak timers are used.
NOTE: The time values for vertical two-zone and horizontal three-zone chambers are for the hot and
cold box, while in double duty chambers these values are when both baskets are in the up/left
position or down/right position.
4.
In the Cycles field, enter the total number of cycles in the test.
5.
From the Soak Method drop-down menu, select the type of soak to be used for the test:
•
Time Only — The timing starts when the basket completes its transfer into the respective box.
Once the timer starts, it counts down to 00:00 and then transfers the basket to the other box.
•
Time + Temp — After the basket completes its transfer, the controller will wait until the boxes are
at their required test temperatures before it starts timing. This usually takes only a minute or two.
After the boxes reach their test temperatures, the timer starts timing. When the timer counts to
00:00, the controller will check to see if the load is at the test temperature. When the load reaches
the test temperature, the controller will transfer the basket to the other box.
•
Temp + Time — The controller waits until the load temperature (sensed by the sensor traveling
with the basket) reaches the programmed test temperature before starting the timer. Once the
timer starts, it counts down to 00:00 and then transfers the basket to the other box.
6.
From the PTC drop-down menu, select whether or not product temperature control (PTC) is enabled
during the test. During normal thermal shock testing, the product temperature will lag behind the box
air temperature. When PTC is enabled, you must program two test temperatures: one for the hot box
and one for the cold box. The controller then senses the temperature at the product and operates the
heating or cooling system at a faster throttle and higher set point to make up for the temperature lag.
The PTC software increases temperature performance at the product by computing the two air
temperature set points based on the load test temperatures, the offset, and the gain parameters. For
more information on PTC gain parameters, refer to your programmer/controller technical manual.
NOTE: PTC is not available for double-duty thermal shock chambers.
7.
When you are done creating or editing the test, do one of the following:
8.
•
To keep the test and any changes you made to it, click the OK button. This associates the test with
the currently selected thermal shock chamber.
•
To exit the test editor without keeping any changes you made, click the Cancel button.
To save the test to disk, do one of the following:
•
If you want to save changes to a previously saved test, either click the Save button on the toolbar
or open the File menu and click Save. The changes will be saved to disk.

Section 5:
Using ThermoTrak II with
Thermotron Oven Controllers
Thermotron oven controllers are manufactured specifically for use with Thermotron ovens. Much of the
ThermoTrak II oven controller interface is identical to the ThermoTrak II interface for standard controllers,
but there are several significant differences because of the nature of ovens. This section describes those
differences.
Viewing and editing ovens
Oven controllers are set up the same as chamber controllers, and are listed in the Available Chambers
window. For information on adding and removing ovens, see “Adding and Removing a Chamber” in
Section 3 of this manual.
The Available Chambers window provides a quick overview of all your ovens and their status. To see
more detailed information about a selected oven, double-click the oven name in the Available Chambers
window. This will display the status window for that oven.
Oven controllers use a scaled-down version of the chamber status window. The oven status window
includes the following information about the selected oven:
•
Temperature reading from inside the oven
•
Current Set Point
•
Output Throttle
•
Initial Value and Final Value for the current profile
segment
•
Ramp Rate for the current profile segment
•
Total Time of the current profile segment and Time

Using ThermoTrak II with Remote Networks
Section 6:
Using ThermoTrak II with
Remote Networks
ThermoTrak II provides the ability to control chambers remotely through another copy of ThermoTrak II.
To do this, one PC must be set up as a server. The client can then connect to the server PC and gain
control of the chambers connected to it. Any remote chambers added to the client’s Available Chambers
list can be operated as if they were local chambers.
A server is limited to no more than ten TCP connections and one modem connection at a time. If at any
time communications fail for any reason, a notification box will pop up on the client PC.
Enabling access to a local network
The PC that is connected to the chamber(s) will function as the ThermoTrak II TCP server. Your IT
department is responsible for setting up the server PC to receive Internet connections.
•
The PC should be part of your local area network (LAN).
•
The PC should have a unique IP address assigned to it.
•
The LAN should be accessible from the Internet.
ThermoTrak II uses port number 11500 to communicate via TCP over intranets and the Internet. If you are
using a firewall on your LAN, set it up to allow requests to be made on port number 11500.
CAUTION: Whatever your firewall settings, you remain responsible for your network’s security.
1.
To enable remote access to your local network, open
the Remote Access menu and click Server Setup.
The Remote Access Server Configuration dialog
box will open.
2.
Click Enable Remote Access Server.
3.
Select an access method:
•
If you click Listen to TCP, the client will need to
know your IP address or computer name if using
DHCP. See your network administrator for details.
•
If you click Listen to Modem, select the modem
to use from the pull-down list. The client will
need to know what phone number to dial to
connect.
NOTE: You can listen for connections via TCP and/or a modem. ThermoTrak II supports up to ten TCP
clients and one modem client simultaneously.
4.
Entering a password in the Server Password field will require a client to supply that password when
trying to connect. This will prevent unwanted access to your local network as a whole.

receive full access. The server maintains an internal list of all of the clients connected to it, which
chambers they are accessing, and what access level they have to each chamber. The server allows only
one client to have full access to a specific chamber. What this means is that if Client #1 connects to
Chamber A with full access, any other clients that request full access to Chamber A will be denied and
connected as view access. Likewise if Client #1 connects to Chamber A with view access, another client
could receive full access later on. One and only one client will ever receive full access to a specific
chamber. At a bare minimum a client will always be connected as view access.
6.
The remote chamber will be added to your local Available Chambers list with the word REMOTE
indicating it is a remote chamber. If full access was granted to the client, the chamber can now be
operated as if it were a local chamber.
Once the client is connected the Connected to:
window is displayed and remains active
throughout the duration of the connection.
This window lists all of the chambers the client is
connected to and what access level has been
granted to each chamber. This provides a constant reminder of the access levels for each chamber in a
network.
7.
To add another remote chamber, click the connect button again and select a new chamber. If you are
already connected you will immediately see the list of chambers available to you.
Downloading chamber information
To download data from a remote chamber, with the selected chamber’s Chamber Status window
highlighted open the Remote Access menu and click Download Chamber Data.

on the toolbar, or
Locking/unlocking a local host
ThermoTrak II includes the option of locking any chambers that are being remotely accessed. If a chamber
is locked out in ThermoTrak II and a local user tries to operate it, a dialog box will pop up, letting the user
know the chamber is locked due to a client connection. (When locked, chambers with 3800, 78XX, 8200, or
88XX controllers will be put into access level 0.)
To lock or unlock the local host upon client
connection:
1.
Open the Options menu.
2.
Click General Options.
3.
Click the Connection tab.
4.
Select yes or no from the Lock local host pulldown menu.

Using ThermoTrak II with Non-Thermotron Controllers
Section 7:
Using ThermoTrak II with
Non-Thermotron Controllers
ThermoTrak II can be enhanced to provide limited support for chamber control systems not manufactured
by Thermotron. If you wish to use ThermoTrak II with a non-Thermotron controller, Thermotron can quote
the cost of developing a custom *.DLL file for you.
This section describes the major differences in using ThermoTrak II to monitor Thermotron and nonThermotron controllers. For general information on using ThermoTrak II, see Section 3.
Adding and removing a chamber
To begin with, at least one chamber must be defined and configured as available to ThermoTrak II. Note
that you are not limited to only one network of chambers. For example, you can define a 9600 baud GPIB
network of chambers on COM 1, and also define a 19,200 baud RS-485 network of chambers on COM 2.
ThermoTrak II can monitor and operate up to four multidrop networks at a time, each with a maximum of
15 instruments (GPIB) or 32 instruments (RS-485).
1.
The Available Chambers window is always open. If
the window is hidden by other windows, open the
Windows menu and click Available Chambers.
2.
Right-click anywhere in the Available Chambers
window and click Add Chamber. This will open the
Edit Chamber Configuration dialog box. From the
Chamber Info tab you can define the parameters
required to communicate with the chamber.
3.
Select Other as the controller type and enter the
name of the *.DLL file for your controller type in the
Custom Controller File edit box. The *.DLL file should
be located in the same directory where ThermoTrak II
is installed. Next, select the appropriate computer
interface, baud rate, and COM port. Remember that
the parameters set here must match the computer
interface settings at the chamber controller.
•
If the chamber is part of a network of chambers,
enter an address value for that chamber in the
Address field. The RS-232 interface does not
support any protocol for addressing, so you must
use either RS-485 or GPIB.

•
If you select the TCP/IP interface, enter the appropriate IP address in the IP Address field as well
as a valid TCP port in the TCP Port field. NOTE: The ThermoTrak II IP address and TCP port
settings must match the IP address and TCP port settings on the controller or, if the controller
does not directly support Ethernet, the Ethernet-to-serial converter.
•
If you select the Demo network type, ThermoTrak II will not attempt any communication with that
chamber. Instead, the software will fill in the chamber’s status with random values, allowing you to
use all of ThermoTrak II’s features for evaluation, training, or demonstration purposes. A Demo
chamber is also useful for creating profiles that later will be assigned to other chambers.
Once the communication parameters are defined, click the Test button.
•
If ThermoTrak II can communicate with the chamber, you will see the chamber’s identification
string and a software version number displayed in the text fields.
•
If there is a communication problem, a message will say “No response from chamber” in the ID
String box. This means either you have a faulty cable connection somewhere, or the
communication parameters are incorrect. You may change any of the parameters to retest the
settings as often as you like. If you need more information on hardware configuration, refer to
Section 2 of this manual.
NOTE: The more chambers you define on the network, the longer it takes ThermoTrak II to scan
the entire network one time.
5.
Once the chamber is properly defined, enter a descriptive name in the Chamber Description text
field. You also can enter a serial number in the Serial # field.
6.
To save the configuration and add the chamber to the Available Chambers window, click OK.
7.
To remove a chamber from the list of available chambers, right-click the chamber name in the
Available Chambers window and click Remove Chamber. NOTE: You must close all chamber status,
data, and graph windows before deleting a chamber.
Viewing and editing chambers
All of the same status screens and dialogs are available for non-Thermotron controllers that are available
for Thermotron controllers. However, some of the fields may not be relevant for your particular controller.
NOTE: For more information on viewing and editing chambers, see Section 3.
Creating and editing profiles
Creating and editing profiles for non-Thermotron controllers works exactly as it does for Thermotron
controllers. However, there are a few things to keep in mind when creating profiles for non-Thermotron
controllers. Not all controllers implement profiles the same way. For example, JC620 controllers use a
separate interval to start a loop, while Thermotron controllers do not. In ThermoTrak II, profiles must
always be created using the “Thermotron” way of doing things. ThermoTrak II will automatically convert
the profile as necessary when it sends it to your specific controller. A byproduct of this is that a profile
might show up as having 10 intervals in ThermoTrak II and 13 intervals when viewed on the actual
instrument. This is okay and is by design.
NOTE: For more information on creating and editing profiles, see Section 3.

Frequently Asked Questions
Section 8:
Frequently Asked Questions
What kind of cable do I need for a ThermoTrak II Ethernet connection?
All 3800, 8200, 8800, and 8825 controllers support standard Ethernet cabling.
•
To connect a chamber to a hub, use a standard straight-through Ethernet cable.
•
To connect a chamber directly to a PC, use a standard crossover Ethernet cable.
My chamber is connected directly to a PC, not on a network. In ThermoTrak II I added a chamber,
selected the TCP/IP interface, set the IP address to match the 3800’s IP setting, and set the port.
I tried the test function and there was no response from the chamber. Can you offer any help?
If your chamber is connected directly to a PC, make sure you are using a standard crossover Ethernet
cable.
How can I update my ThermoTrak II software?
To download and install ThermoTrak II, follow these steps:
1.
Open your web browser and navigate to:
http://www.thermotron.com/_customer/downloads/thermotrak-software-upgrade-andgeneric-manual
2.
Begin downloading the software by right-clicking on the file name and choosing ‘Save Target As…’
3.
Open the file using zip-capable software such as WinZip.
4.
For further instructions, view the “readme” file using Microsoft Notepad.
5.
For your ThermoTrak II serial number, enter the serial number of your chamber as well as the twodigit number of the month you received your chamber. For example, if your chamber serial
number is 60354 and the month you received your chamber was September, your ThermoTrak II
serial number will be 6035409. Please record this serial number, as you will need it to obtain
additional software updates.
Why is the data graph different from the profile editor graph, including the colors?
The data graph shows what your chamber has done or is doing (depending on what part of the graph
you are viewing). The profile editor graph shows what your chamber will do when you run the profile
you are editing. Also, the data graph displays whatever process variables, set points, and/or throttles
you selected in the Data Log tab, while the profile editor graph displays only the set points you
entered in the profile.
The reason the colors are different is that you can change the colors displayed in the data graph, but
you cannot change the colors displayed in the profile editor graph.
Why does the chamber status window show a deviation of 1°C while the profile editor shows a
deviation of zero?
Any time you are not running a program the chamber status window reflects the value of the Manual
Mode deviation setting. Only when you are running a program will it show your current interval’s
deviation reading. This is why, when you stop the program, the deviation setting changes.

Frequently Asked Questions
ThermoTrak II User’s Guide
What is the correlation between the chamber status window and the data graph?
The chamber status window always shows the current readings for your chamber. The data graph can
show both current and past readings. If you click Scrolling in the Log Settings tab, the graph will
move as new plot points are sampled, which allows you to always view the end of the graph (that is,
the most recent data). At any given time those readings at the end of the graph should be the same as
the readings in the chamber status window.
Also, the data graph displays whatever process variables, set points, and/or throttles you selected in
the Data Log tab, while the chamber status window displays all process variable, set point, throttle,
initial value, final value, and deviation readings.
What is the meaning of the colored bars above the data graph?
As your testing moves along, more and more plot points are sampled from the chamber status. As this
happens, your graph is updated and re-plotted. The color-coded bar above the graph indicates what
operating mode your chamber was in during the time displayed on the graph (green = run mode,
yellow = hold mode, red = stop mode).
I’m trying to use the Back 1 Day feature to see the data graph for a day when I ran a test, but the
date doesn’t change. Why?
Has ThermoTrak II been running and communicating with the chamber continuously since the test
began? You can only scroll the data graph back as far as ThermoTrak II has been running and
communicating with the chamber. If, for example, you started ThermoTrak II at 11:10 a.m. on January
26, you would not be able to scroll back to an earlier date and time than 11:10 01/26.
How can I print a data graph of an entire test on a single page?
The Graph Settings tab allows you to adjust the data graph’s X Axis. The X axis represents an amount
of time in days:hours:minutes format.
For example, say you have finished running a three-day test and you want to print a one-page graph
of that three-day period. To do so, perform the following steps:
1.
Right-click inside the Data Graph window, select Properties, then select the Graph Settings tab.
2.
Make sure the Scrolling check box is cleared.
3.
Select an X axis Minimum of 0:00:00 and a Maximum of 3:00:00.
4.
To label the graph’s X axis with real times and dates, clear the Use relative times check box.
5.
Click OK.
6.
Manually scroll the graph by left clicking and holding anywhere inside the graph and moving your
mouse back and forth until the graph displays the three-day period of the test.
7.
Click the Print button.
Why is it that, after a test, the process variable no longer matches the set point?
The chamber status window always shows the current conditions of your chamber, even if a test is no
longer running. If your chamber has been operating above or below ambient conditions, it is now
drifting back toward ambient.
