8200+ Display Module Instruction Manual Setup
hermotron Industries his generic manual is not intended to be used to operate your equipment. 1-1
Section 1: Setup
Introduction to the 8200+ display module
NOTE: For information on the CM2 control module, refer to the CM2 Control Module Technical Manual.
The 8200+ display module consists of three main components:
•A miniature single-board computer (MSBC)
•A liquid crystal display (LCD)
The 8200+ motherboard is custom designed to interface with Thermotron’s line of instrumentation. The LCD is a
seven-inch-diagonal widescreen display with an LED backlight and resistive touch capability. For more detailed
information on the 8200+ display module, refer to Section 6 of this manual.
Using the touch screen
The touch screen monitor is the only user input device. To push a button or make a selection, use the supplied stylus
to touch the appropriate area of the monitor screen.
When you touch a specific area of the screen, one of several things could happen:
•The button will remain “in” and perform the desired function. For example, touching the Manual button will
switch the display to the manual mode screen.
•A radio button, check box, or line will be selected. Touching the radio button, check box, or line a second time
will deselect it.
•A drop-down menu will appear, enabling you to make a selection from a list.
•The alphanumeric keypad will appear. Use the keypad to enter an alphanumeric value into the field. Press Enter
to accept the new value, or press Cancel to close the keypad without entering a new value.
For example, when you touch a channel name field on the Chan/Aux Names panel, the keypad will appear,
indicating that you can enter an alphanumeric value into the field.
The alphanumeric keypad defaults to lowercase letters. To enter uppercase letters or the symbols on the number
keys, press Shift and then the desired letter keys. To return the keypad to lowercase letters, press Shift again.
The Backspace key deletes the character to the left of the cursor. The left and right arrow keys, located on either
side of the Space key, move the cursor to the left and right in the display field at the top of the keypad. The
8200+ will highlight the last key pressed.

Setup 8200+ Display Module Instruction Manual
1-2 his generic manual is not intended to be used to operate your equipment. hermotron Industries
•The numeric keypad will appear. At the top of the keypad is a small display
field as well as an indication of the allowable range of the selected field.
Use the keypad to enter a numeric value into the field.
For example, when you touch the Deviation field on the Program Creation
panel, the numeric keypad will appear, indicating you may enter a value
between 0.0 and 25.0 into the field.
The 8200+ will highlight the last key pressed. Press Enter to accept the new
value, or press Cancel to close the keypad without entering a new value
into the field.
Recommended cleaning procedure
Due to the nature of touch screen interfaces, the surface of the LCD has a tendency to accumulate dirt and
fingerprints, and requires regular cleaning. The surface of the LCD is very durable and resistant to most cleaners, but
the bezel assembly covering the 8200+ is not watertight and precautions should be taken to prevent any liquid or
cleaner from reaching the surface of the electronics behind the bezel. Wiping the LCD with a soft, dry cloth is the best
cleaning procedure, but a liquid glass cleaner may be used to remove stubborn marks. The glass cleaner should be
used to moisten the cloth and the damp cloth used to wipe the display, rather than applying the cleaner directly to
the surface of the LCD.
USB support
USB is included in the 8200+, mainly for the support of USB flash drives. The 8200+ supports all of the most likely
USB devices that would be used with a chamber: flash drives, keyboards, mice, hard drives, floppy drives, etc. Any
flash drive or other storage device connected to the 8200+ must be formatted as FAT32 in order to be recognized by
the operating system.
In addition to the USB driver support limitations in the 8200+, there is also a USB power distribution limitation. A USB
master can provide power to its devices, and the standard allows for two classifications of devices: high power and
low power. High-power devices require up to 500 milliamps of current to operate, and typically are larger devices like
a USB-powered floppy drive. Low-power devices will be more common in 8200+ applications and require no more
than 100 milliamps to operate. Examples of low-power devices are flash drives and anything that has its own power
supply. Due to limitation on the MSBC, the 8200+ can support only one high-power USB device at a time. Multiple
low-power devices may be used with the 8200+.

8200+ Display Module Instruction Manual Setup
hermotron Industries his generic manual is not intended to be used to operate your equipment. 1-3
File functions
The 8200+ uses standard Windows
dialog boxes for opening and
saving files (such as program files or
graph settings files). The buttons at
the top of the dialog boxes also
allow you to copy, paste, delete,
and rename files. Files may be
loaded from and saved to the
8200+ micro SD card, a network
drive, or an external USB drive.

Function buttons
The function buttons are always available on the right side of the touch screen. The following paragraphs list the
function buttons and briefly describe their functions.
The
Main
screen displays all currently active co
ntrol channels in a large, easy
-
to
-
read format. In
addition to the current value of each channel, the current setpoint and throttle also are displayed.
The
Prog Stat
screen displays the status of the currently running or most recently run program. The
status bar at the top displays the name of the current test as well as its overall progress. (NOTE:
GSoak intervals are not counted towards the overall time). Any active channels for the current interval
appear on the left side of the screen, with the time remaining for the current interval on the right of
the screen. Any options that are enabled are highlighted in the Active Options section.
The
Manual
screen allows you to manually control
chamber
setpoints and options. Whenever any
option is changed, you must press un to commit the changes to the chamber. This allows more than
one setpoint or option to be changed at once. NOTE: Some options prevent other options from
being active at the same time. For example, if PTC is enabled, Humidity will be unavailable until PTC
is unchecked.
The
Graph
screen allows you to view the history of the chamber in a graphical format. Nearly
everything about the chamber is logged to internal storage every six seconds for the entire life of the
controller. Press the Setup button to select what data you wish to view, and also to set up the look
and parameters of the graph. Goto allows you to select any date to jump to immediately, while the
navigation buttons move back and forth one screen at a time. Auto Y will scale the graph to the
current minimum and maximum values of the data on the screen. Cursor allows you to pinpoint the
exact data values of any point in time.
The Sys Info panels provide the following status and diagnostic information:
● Monitor channels ● IO diagnostics
● Activity log ● General system information
● Control module
An
8200+
Program
is made up of a series of intervals that are executed in sequence. Each interval
can have its own set of options configured, including which channels are enabled and which auxiliary
outputs are turned on or off. To enable a guaranteed soak (G-Soak) interval, set the deviation for the
desired channel to non-zero, then check the G-Soak option beneath the time. When the program
reaches this interval, the time will not start counting down until the value of the channel is within the
defined deviation, ensuring the chamber spends the full time span at the desired temperature,
humidity, etc.
The Setup panels allow you to modify the following settings:
● General system setup ● Service messages
● Control parameters ● System events
● Computer IO ● Channel and auxiliary output names
The
T
-
Alarm
panels allow you to set up, view, and calibrate the Therm
-
Alarm.
NOTE
: The

If the 8200+ is in run or hold mode and a power failure occurs that is longer than the Max Off Time setting, the
8200+ will automatically power up in the mode selected under ecover Mode. If the Max Off Time is set to
0:00:00, this feature is disabled and the 8200+ will power up in whatever mode it was in when power was lost.
1. To enable or disable power fail recovery, check or uncheck the Power Fail ecovery check box.
2. For Max Off Time select the number of hours and minutes power must be lost before the 8200+ enters
power failure recovery mode. The keypad will display the allowable range of each field.
3. From the ecover Mode drop-down menu select a mode to power up in following any power failure that
exceeds the Max Off Time setting. The available settings are:
•Stop: The 8200+ will stop the test that was running when power failed.
•Hold: The 8200+ will hold the test at the point reached when power failed.
•un: The 8200+ will return to the mode it was in when power failed.
•estart: The 8200+ will start running the test again from interval 1.

Refrigeration Options
.S.A. Time
When running a program, the refrigeration system anticipator time ( .S.A. Time) is the number of minutes the
8200+ will pre-cool the mechanical refrigeration system before entering a zero-time cooling interval (normally a
guaranteed soak). This reduces the lag time caused by cooling the refrigeration hardware.
•Select the .S.A. Time field and enter or modify the setting. The keypad will display the allowable range.
Auxiliary Cooling
Some chambers are equipped with optional liquid nitrogen (LN
2
) or carbon dioxide (CO
2
) auxiliary cooling
systems. When the refrigeration system is operating at full cooling throttle, the auxiliary cooling system can be
operated for a programmed percentage (duty cycle) of a selected time frame.
For example, if you set the auxiliary cooling time frame to five seconds and the duty cycle to 30%, the auxiliary
cooling system comes on for 1.5 seconds (30% of five seconds) and then goes off for the remaining 3.5 seconds
of the five-second interval. If you set the duty cycle to 100, the auxiliary cooling system comes on and stays on
for as long as the refrigeration system is operating at full cooling throttle.
Under Auxiliary Cooling select a field and enter or modify the setting.
•Enter the length of the Time Frame in seconds. The keypad will display the allowable range.
•Enter the percentage of the Duty Cycle.
Humidity emperature Range
NOTE: For your chamber’s humidity temperature range, refer to the specifications listed in your chamber manual.
Under Humidity Temp ange select the High Limit or Low Limit field.
1. The numeric keypad will appear. The keypad will display the allowable range.
2. Enter the temperature limit, then press Enter.

Control Parameters panel
CAUTION: The 8200+ programmer/controller was factory-tuned and should not need to be re-tuned unless
the product requirements change enough to affect the performance of the chamber. Incorrect values could
damage your equipment and/or product.
NOTE: To tune control parameters, the 8200+ access level must be Lab Manager or higher. For information on tuning
the control parameters, see Appendix B. For information on tuning the product temperature control (PTC) control
parameters, see Appendix C.
Control parameters adjust the performance of the chamber around the setpoint. As the chamber nears the setpoint,
the 8200+ adjusts the chamber throttles to provide a smooth ramp to the setpoint. To prevent overshooting and
oscillation around the final setpoint, the refrigeration, heating, and other systems must be damped as they approach
the setpoint. To maximize chamber performance, you must also compensate for lag times.
Up to four groups of chamber parameters can be entered into the 8200+ for each control channel. This allows you to
select chamber performance appropriate for the type of interval or program you are running. For example, in one
interval you may want less control during a ramp between two extreme temperatures, but in the next interval you
may want more control to maintain a constant temperature. To achieve the two levels of control, two groups of
parameters can be programmed.
•To enable multiple groups of control parameters, select the Use Multiple Groups check box.
•To restore the control parameters that were set at the factory, press the estore Factory Defaults button.

Control parameter files
You may also save and load control parameters to and from a file using the Save As and Open buttons. This
provides the ability to save sets of custom control parameters in addition to the four groups already available.
Control parameters files can also be associated with a program such that every time a program runs it will use
the control parameters in a file instead of the currently loaded parameters. To do so you must save a control
parameter file with the same name as the program you wish to associate the parameters with.
For example, if you have a program named Sample Test.mzp, and you save a set of control parameters in a file
named Sample Test.prm, every time you run Sample Test it will automatically use the parameters in the Sample
Test.prm file.
Computer IO panel
NOTE: To change any computer interface setting, the 8200+ access level must be Lab Manager or higher. For more
information on computer interface settings, refer to Section of this manual.
Each 8200+ display module is equipped with two independent computer interface ports. The 8200+ can
communicate through both ports at the same time:
•Network (TCP/IP): Communication through the 8200+ display module’s Ethernet connector. This connector is a
standard eight-pin RJ 5 connector, but only makes use of four pins (two twisted pair). It is intended to enable a
personal computer to communicate with an 8200+ display module over a standard Ethernet network.
•Computer I/O: Communication through the control module com port capable of either RS-232, RS- 85, or GPIB
(IEEE- 88).
The following paragraphs discuss the various communications protocols and how to properly configure the 8200+ to
use them.

Network ( CP/IP)
The TCP server can handle multiple simultaneous connections. Under Network (TCP/IP) select each field to
modify its setting.
1. Select the Enable Computer I/O check box
2. Select the Enable Web Server check box
3. Select the type of TCP/IP addressing (either DHCP or Static).

6. Enter a valid Gateway address.
7. Enter a valid Port address. NOTE: Thermotron recommends leaving this at the default.
8. Select the desired Terminator.
9. Select the Send Acknowledgement check box. The 8200+ uses the send acknowledgment function to
provide feedback to the computer when it has finished processing a non-query command. When enabled,
the 8200+ will echo back the error code to the host computer when the non-query command has been
processed. This serves two functions:
•When the error code is received by the host computer it knows that the 8200+ has finished processing
the command. If a response has not been received within two seconds, the command should be re-sent.
•A non-zero error code response indicates that the 8200+ did not process the command properly and it
should be re-sent. Without this function, the 8200+ could send commands too fast, causing some
commands to be lost.
10. Select the desired Cmd Compatibility. Command compatibility allows the 8200+ to emulate a legacy
instrument’s command set. For more information see “Legacy instrumentation command compatibility” later
in this section.
Adding and removing network shares
