Warning
Permanent damage may be done to the thermometer if the power supply connections are not done correctly.
In particular, do not connect the power input (18-24 VDC) to any of the analog output connectors. Note that
the 20 mA analog output options are self-powered interfaces (by opposition to loop-powered interfaces), and
thus do not require any external supply. Maximum loop impedance should be kept at 400 Ω; internal
impedance is approximately 0.7Ω.
With 0-10 volt analog outputs, avoid shorting output leads together; as this may destroy the electronic drivers
inside the unit; external impedance must be kept at all-time at 10 kΩ or more. Unit must be returned to
Neoptix for repair, not field repairable.
Fiber optic probes and extension cables are fragile, and will break if the bending radius becomes less than
~1 cm, even temporarily. Probe breakages are not covered under the standard Neoptix warranty.
To assure cleanliness of optical connectors, keep caps on unused connectors at all time. This is also required
during operation, as parasitic light entering via unused connectors into the Reflex module may cause false
temperature readings, even on other channels.
The Neoptix Reflex products are CE marking certified.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
this device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.

2 INTRODUCTION
Congratulations on the purchase of your Reflex thermometer product! Your new temperature sensing
system will soon allow you to take full advantage of the benefits inherent to fiber optic sensing technology. It
offers accurate and reliable temperature measurements, combined with extraordinary insensitivity to EMI/RFI,
high voltage insulation and disturbance free sensing due to the non-electrical nature of the sensor element
used.
Not only does the Reflex family of products gives consumers’ access to reliable measurements, but it also
offers a simple user interface that makes the technology easy to use. Moreover, no special calibration is
required when changing the fiber optic sensor elements.
The thermometer is packaged in a small splash proof package, which is ideally suited for industrial
applications. If desired, the package can easily be mounted in standard rack configurations (a mounting kit is
offered as an option).
The standard configuration is offered with an RS-232 interface as well as an analog output feature (1, 2 or 4
channels) that can be used for remote interfacing purposes. In addition, a green fluorescent display makes it
o
o
easy to see the temperature for up to 4 channels, either in Celsius ( C) or in Fahrenheit ( F), even in dark
areas; it also includes a simple 3-key keypad that gives the user access to all built-in features; these standard
features are great for laboratory applications.
The “Lite” version of the newly upgraded OptiLink software package is now shipped standard with all Reflex
systems. A Pro version (with all “Lite” limitations removed) is available as an option. Windows XP or later is
required, as well as one RS-232 serial port for each thermometer. OptiLink has been tested for use with
Windows 7.
This version includes support for double-calibration Reflex systems (optimized for both Neoptix and older
Nortech-Fibronic Inc. probes); the keypad can be used to toggle calibration type, or the selection can be
made from OptiLink.
Important information: this new and improved version of the Reflex does not require a user reference
adjustment procedure for operation. In addition, some RS-232 commands have changed, to exploit the
additional capabilities included in this new version; for the most part, these changes should have minimal
impact on software compatibility; see Section 6.4.

The following presents a full description of the user interface as well as detailed instructions on how to use
the thermometer.
1) Sensor status light(s): There are a total of up to 4 lights for this, one for each channel. These indicators
inform you about the system status, as applicable to each channel. If any remains off, this indicates that
either that channel is disabled or there is a problem with that sensor (or with the optional patch cord
connected to it). Check if all optical connectors are correctly mated or if the sensor fiber (or patch cord) is not
broken.

A quickly flashing light indicates that the calibration table applicable to this channel is corrupted. If this
happens, the integrity of the temperature readings for this channel is not guaranteed; please use precaution.
Contact Neoptix for further information on how to resolve this issue.
2) Serial communication status lights: These indicators are directly connected to the Tx and Rx lines of
the RS-232 interface. Useful for monitoring activity on the serial line.
3) RS-232 communication interface: This port is used to configure and extract information for the
instrument. This DB-9 connector uses the same pin-out as a COM port on a PC computer. Use a simple pinto-pin wired cable (not a null modem cable) to connect to a computer. See below for a complete description
of the serial commands that are available.
4) 2 x 16 Display: Under normal use, the display will show the temperature readings for the user selected
o
o
channels; the temperatures are displayed in either C or F. However, when the FNCT key is used,
information is displayed to guide the user in making the selections (see item 5 below).
5) FNCT and SET keys: When the FNCT key is not activated; the display will show the temperatures for the
requested channels. The FNCT key allows the user to scroll through the menu items. All settings are kept in
permanent memory, until changed again by the user, using either the keypad or a RS232 command.
This key allows users to scroll through the different options.
This key allows users to browse from field to another, for options that have many fields.
This key allows users to set a value to the selected field.
The description of each of the menu items is:
1- Sampling rate: Adjust the resolution of the display. In Fast mode, the instrument focuses on faster
response time. In Slow mode, the focus is on higher resolution; this is achieved by smoothing the last
few temperature measurements, which tends to reduce the noise, but to increase the effective
response time. In Slow mode, the display shows gives temperatures in hundredths of degrees, while
in Fast mode the display is in tenths of degrees. The display refresh speed is the same for both
settings.
2- Ch Enable Scan: Enable or disable the reading of a channel. Channels that are turned off are not
read, thus allowing the “on” channels to be read faster.
3- Temp. Unit: Enable users to change the temperature unit of the instrument. The thermometer will
continue to display temperatures using the newly selected unit.
4- Calibration type: You have the choice between “Neoptix probe” and “Nortech Fibronic Inc. probe”.
6) Power switch. Make sure the Reflex power supply module is connected and powered. At power on, a
series of messages are displayed (actual information may slightly differ):






This is the calibration date (format YY/MM/DD). “NE” indicates that the calibration for Neoptix probes is
currently active; alternatively, “NO” will be displayed when the Nortech-Fibronic Inc. calibration has been
chosen.

Then temperatures should then be displayed, assuming they are correctly connected, and so forth. If
temperatures are unreadable, ----- will be displayed.
7) Power status light.
8) Sensor connector(s): These are ST type connectors, mating to each of the 4 optical temperature
sensors. If you need to extend a sensor fiber, you should use optional patch cords that are available from
your Neoptix supplier. For thermometers that have 1 or 2 channel(s), only 1 or 2 sensor connectors are used.
Warning: The fiber type that is used with your Reflex thermometer is of a special type, and it is
recommended that you get ALL of your patch cords from Neoptix or a Neoptix authorized distributor.
9) Analog output connector(s): There are a total of 1, 2 or 4 such connectors, one for each channel. Prior
to shipment, your Reflex thermometer was factory set to one of the following configurations: 4-20mA or 0-10V
output. The minimum analog output value corresponds to minus 100°C and the maximum analog output
value corresponds to 300°C. The thermometer normal range is from minus 80°C to 250°C, so a minimum
value indicates an under-range error; likewise, a maximum value indicates an over-range error condition.
Note: Reflex thermometers that have extended range, such as cryogenic version, may differ; contact Neoptix
for more information. If there is a sensor problem for a given channel, the analog output may take one of the
following 3 states (refer to the RS-232 “o” command, Section 6.4):
a) It will toggle between the minimum and maximum values, at approximately 0.5 Hz; this indicates a
sensor problem for that channel (o0). This is the default setting; to change it, you will need to use the
RS-232 “o1” or “o2” command.
b) The analog output is forced to its maximum value (o1); this would indicate a “too-hot” situation.
c) The analog output is forced to its minimum value (o2); this would indicate a “too-cold” situation.
Warning: 1- Do not connect any external voltages to these outputs; this may cause permanent
damage to the thermometer unit. 2- Avoid shorting output leads together, as this may destroy the
electronic drivers inside the unit.
Note: If the Reflex unit is in “sleep” mode, the analog outputs will keep their values until the Reflex acquires
new temperature values.
10) 18 Volts DC power connector: You can use a DC power supply from 14V to 28V; note that at 15V or
less, you will be unable to use more than one (1) 500Ω load at the analog output, for all current output
configurations. There is an internal fuse, to protect the system in case of electrical problems; this fuse is not
user changeable.

5 USING THE TEMPERATURE PROBES
5.1 Caution
Each time you connect a temperature probe to the unit, the probe optical connector should be cleaned
beforehand. Otherwise, particles of grease or dirt may obstruct the device internal connector and affect the
measurements by completely blocking the signal or by generating too much attenuation when using a long
fiber length.
Never use a cloth other than the type recommended for fiber optic cleaning. Dampening the cloth with pure
isopropyl alcohol ensures good cleaning. OptiPrep pads can also be very useful (available from any fiber
optic component reseller).
Occasionally, clean the inside of the bulkhead connector (attached to the thermometer) with a wipe or cotton
swab dipped in alcohol (2.5 mm mini foam swabs work best).

5.3 Warning
The T1 probe is quite fragile and it must be handled carefully. Please note that any probe damages are not
covered by the standard warranty.
The probe tip is made of silicone rubber. Although silicone is resistant to a large number of chemical
aggressors, strong acids or alkali may damage it, especially at high temperature and/or if used for extended
periods of time. Warning: Solvents and fuel oils can cause problems for silicone rubber.
Neoptix also manufactures probes that have their tips made of epoxy. Just like silicone, epoxy resin is
resistant to a large number of chemical aggressors, strong acids or alkali may damage it, especially at high
temperature and/or if used for extended periods of time.
Contact your distributor for additional chemical compatibility information.
Do not expose your probes to temperatures that are higher than specified. Permanent damage can be
caused to probes that have been exposed to temperatures that are higher than their limits.
5.4 Working with long probes
This note is important when using probes or extensions that have a combined length of 100 meters or more.
Working with long probes or extensions presents special problems. To limit the amount of back reflection
caused by the fiber optic connector located on the thermometer unit, you may have to use a matching gel
optical couplant in the connector. This gel is a grease-like compound with high clarity, good resolution
properties and a refractive index close to quartz. Apply the gel onto connector end faces.
Avoid disconnecting the connectors for which gel has been used. In other words, it is recommended to use
the gel only for permanent installations. If the connectors are disconnected many times, you may have to
clean entirely the connector assemblies that have had the gel; this may require opening the instrument
enclosure to remove the excess gel.
Note that it is not required to use this gel with connectors that are far away from the thermometer electronic
unit.
5.5 Working with cryogenic probes.
The use of a cryogenic probe required special attention. In particular, the probes become more brittle at very
low temperatures. Avoid cycling the probes quickly between cryogenic temp and ambient temperatures, as
this may cause material fatigue at the probe tips.
Warning
Always wear protective gloves and clothing when working with cryogenic material.
Never use general purpose probes at cryogenic temperatures. Neoptix sells special probes that can be used
at cryogenic temperatures.
Please note that your Reflex thermometer will require a special factory calibration to be used at cryogenic
o
temperatures (below -80 C). Consult Neoptix for more information.

6 SERIAL COMMUNICATION DESCRIPTION
You can communicate with your Reflex thermometer via the standard RS-232 link. A description of the cable
requirements is given above, under front panel item # 3.
RS-232 functions (or commands) can be accessed with a simple terminal, or using OptiLink software
package or simply with a computer and communication software (such as Windows Hyper Terminal). Your
software should be set at 9600 Baud, 1 Stop-Bit and No-Parity.
6.1 Using OptiLink Console
The New OptiLink software package now includes a convenient console option that can be used to “exercise”
your Reflex serial communication protocol. With this console, there are almost no more reasons to use
HyperTerminal or equivalent to use the serial commands that are described in this Section.
Refer to the next Chapter for instructions on how to use OptiLink.
6.2 Using HyperTerminal in Windows
2
Hyper Terminal is a standard Windows program (XP and previous versions ) that can be easily used to
exercise your Reflex thermometer. To use Hyper Terminal you first set its properties as follows:
1- In the “Connection Description” window, enter a name that suits you, such as “Neoptix-Reflex”. Click
OK.
2- In the next window, “Connect To”, select COM1 (or another COM port, if you are planning to use
another port than COM1) in the box called “Connect using”. Click OK.
3- Then the COM1 Properties window will come up. As indicated above and as shown in the figure at
right, set the port parameters to 9600 Baud, 1 Stop-Bit and No-Parity. Click OK.
4- You are ready to go. Type “h E ” to test your setup (see below). Warning: the characters that you
enter are not echoed back to you!
2
Vista, Win-7 and Win-8 users: HyperTerminal is not included with Vista and subsequent Windows versions.
However, an equivalent program (HTPE) can be downloaded (for a fee) at the following website:
http://www.hilgraeve.com/htpe/download.html. Tera Term (freeware) has also given good results; see
http://ttssh2.sourceforge.jp/ .

The following is the menu as displayed by the instrument when sending the “h” command. Note that the
RS232 interface can also be used to upgrade the thermometer controlling firmware, without opening the
thermometer case or changing any memory IC’s. Instructions to perform an upgrade are normally sent with
the upgrade program; a PC compatible computer will be required to perform such firmware upgrade.

6.4 Detailed description of RS-232 commands
All commands must be terminated by a carriage return character ( E
). When more than one argument is
required, each argument must be separated from the next one by a blank or space character. Characters are
not echoed back to your controlling device. Command are case sensitive.
Every time a command is executed successfully by the thermometer, the “*” prompt character is
automatically sent, except in case of failures when the “Errx” error code is sent instead. Do not send your
next command before receiving either the “*” or the “Errx” prompt. The “[“ and “]” characters must not be
typed in; they are used here for ease of reading only.
Most commands are applicable to all Reflex models (different number of channels). When using one-channel
model, the channel number [i] must not be typed in.

o

“b” This command returns the internal temperature of the enclosure. The temperature is returned in C or F
unit, as specified by the “u” command.
Ex:
“b:32.2 E “
“e[[-]1 [-]2 ... [-]n]” This command is not recognized by the one-channel model. Specify which channels
are enabled and read by your Reflex. Preceding a channel number with the minus sign “-” will disable that
particular channel. This command is useful to ignore channels that are not currently used. Enter the channel
numbers that you would like to use, each one separated by a blank character.
Ex:
“e-1 2 3 E “, to enable only channels 2 and 3 and at the same time to deactivate channel 1.
“f[j]” or “f[i j]” This command forces an actual temperature reading (j) for channel # i; any resulting offset
will be applied to all future measurements for that channel. This is useful to compensate for small
temperature deviations that may occur between sensors. This is also called a one-point calibration correction.
o
A maximum offset of +/-5 C is recommended; if it is required for you to force a larger offset, your thermometer
probably requires a new factory calibration; consult your distributor or factory for more information. This
command can also be used to force older Nortech Fibronic inc. probes to read similar temperatures as
the newer Neoptix probes. This command alters the internal calibration of the instrument. Always follow the
recommended procedure, as given below.
Force temperature procedure:
I.
II.
III.

V.
Apply a stable and known temperature to the sensor tip
Check the display reading for abnormal deviation from the known temperature
Send the “f” command followed by channel number, a blank character and the reference
temperature value (example “f2 27.0 E “). Temperatures must be entered in units as
specified by the “u” command
Wait a few seconds
Confirm that the readings correspond to the known temperature.
Note: You can revert at any time to the factory calibration using the “f” (or “f[i]”) command (ex: “f2 E
will in effect clear any offset that you may have entered.
”). This
Note: Always make sure you are reading a valid temperature value before using the “f “ command; otherwise,
your thermometer may display a random value for a channel where the “f” command has been used.
“gskip[i]” This command is useful to eliminate annoying dropouts that can happen when using “weak”
probes. The parameter “i” indicates the number of scans that the Reflex system will perform before actually
indicating that it cannot read the probe on a specific channel. The range of i is from 0 to 9; a value of 0
indicates that the Reflex makes no attempt at removing dropouts. A value of 3 to 5 is recommended,
especially for transformer applications. This command is active even when the sleep command is valid, but is
limited to a timeout of 2 minutes.
“h” Displays a help menu screen (see above).
“i” Returns general information regarding the instrument, as well as some parameters that have been
programmed previously in the thermometer (either by RS-232 commands or via the keypad):

“l[i]” This command is useful to prevent a local user from configuring the thermometer using the keypad. “i”
can take two values: “+” or “-“; entering “l+” will lock the keypad, while “l-“ will unlock it, thus enabling a user to
make local changes. If a user attempts to use a locked keypad, the message “LOC” is briefly displayed and
the command is rejected. A locked keypad can only be unlocked using the “l-“ RS-232 command.
“n+o” or “n+e” This command can be used to change the calibration type that is active at any given time.
“n+o” should be used to enable the Nortech-Fibronic, Inc. calibration, while “n+e” should be used for Neoptix
probes.
“o[i]” This command can be used to change the behavior of the analog output(s) when the Reflex
thermometer cannot read a temperature for this channel. “i” can take one of three values:
a)
i=0. This is the default value, to assure compatibility with older Nortech Fibronic inc. Reflex
thermometers. With this setting, the analog output will oscillate between its maximum and its
minimum value at a rate of approximately 1Hz.
b)
i=1. In case of a probe problem, the analog output for this channel will be forced to its maximum
possible value (e.g., 10V or 20mA).
c)
i=2. In case of a probe problem, the analog output will be forced to its minimum possible value (e.g.,
0V or 4mA).
“p[i]” This command allows the user to force the Reflex thermometer to enter in sleep mode (p+) or to exit it
(p-). Once in sleep mode, the thermometer will acquire new temperature values ONLY when the “t” or “t[i]”
command is received; when the t command is received, the thermometer will immediately scan all enabled
channels, and the new temperature values will be displayed and sent through the RS-232 link, after which it
will return again in sleep mode (there is no need to resend the p+ command again).
a)
When the thermometer is powered on, the sleep mode is always disabled.
b)
When new temperature values are acquired, these new values will be shown on the display (if
present) for about 40 seconds, after which “Sleep mode” will be displayed.
c)
The analog outputs will keep the last temperature readings, until new ones become available.
d)
The front panel led status lights will keep their values until new readings are acquired.
“q” “q” allows for selecting the fast (q+) or the slow (q-) acquisition mode. This is equivalent to the Sampling
Rate selection that is available on the Reflex keypad. In slow mode, the last 4 temperatures are averaged
(smoothed) before being displayed or sent to the RS-232 port; this provides a better reading at the expense
of being slower.

“s[j]” or “s[i j]” This command will set the analog output span for the analog channel # i (if using a multichannel thermometer, the “i” parameter specifies the channel to which the command is addressed). The “j”
parameter specifies the span that can range from 1.0 to 1000.0, in temperature units that are defined by the
last “u” command.
“t” or “t[i]” Returns the current temperature reading for channel # i. “---.-” is displayed if the specified channel
number is not currently enabled or when no valid temperature is available for the requested channel.
However, during the initial warm-up time, the error “Err1” is sent in response to the “t” command. For multichannel instruments, if the “t” command is received without parameter, the temperatures for all channels are
o
o
returned. All temperatures are returned in C or F unit, as specified by the “u” command.
Ex:
“t4 E “ will return the temperature for channel # 4.
“t E ”, with the Reflex-4 thermometer, will return:
+24.3<CR>
+24.5<CR>
+24.7<CR>
+24.4<CR>
*
The “t” command is also available in a special “ta” version, that can be useful for continuously and
automatically monitoring all enabled channels. This special mode is recommended when automatically
acquiring temperature readings with a suitable data-logging software, and can be activated by issuing the
“ta+” command, or deactivated with the “ta-“ command. Once activated, the following information is
automatically sent when the temperature on a channel has been acquired:
“C:I;T: ±xxx.x<CR>”
Where i is the channel number, and xxx.x is the temperature reading (signed number). For the Reflex-1
model, i is always 1.
“u[i]” Set units of measurements to either Celsius (i=c) or Fahrenheit (i=f). Note that this unit selection is the
same as the temperature unit selection made from the keypad (if the display option is installed).
“, to select ºC (Celsius).
Ex:
“uc E
“wtune[i]” This command can be used to increase the optical integration time of each channel (each of the 1
to 8 channels are treated independently) to force the Reflex system to read temperatures when the optical
signal is weak, at the expense of a slower response (slower temperature update frequency or rate). This
command (wtune+) enables this feature for all channels (individual channel cannot be enabled or disabled). It
should be noted that in general the scanning rate of the system would slow down when this command is
enabled. It is highly recommended for power transformer applications.
Warning: When wtune is enabled, and that a probe is inserted, or removed, it may take some time (several
seconds), when multiple channels are being optimized at the same time) for the Reflex to detect the probe,
due to the optimization process that takes place.
“y” The “y” command can be used to confirm the “signal strength” of a probe and/or its connection. It can be
used as a diagnostic tool to confirm the good operation of a probe and its patch cord (if applicable) connected
to a channel. The returned value can be between 1.00 to approximately 3.00; a higher value is better. A
minimum of 1.25 is required for a channel to return a temperature.

CH3 power: 2.38, lamp attenuation: 125, CCD time: 500ms (auto)<CR>
CH4 power: 1.09**, lamp attenuation: 125, CCD time: 500ms (auto)<CR>
*: Value: Auto (when wtune+ is active) or Fixed (when the wtune command is disabled).
**: 1.0 to 1.1 indicates that no probe is detected for this channel.

“z[j[“ or “z[i;j]” This command is used in conjunction with the “s” command, as it sets the temperature that
corresponds to the analog zero (minimum value of analog output). For multi-channel models, the “i”
parameter specifies the channel to which the command is addressed; valid values are 1, 2, 3 and 4. The “j”
parameter specifies the zero temperature value, and can range from -100.0 to 1000.0, in units that are
defined by the last “u” command. Factory default is -100.0; Reflex thermometers that have been factory
calibrated for cryogenic temperatures have a lower setting.
6.5 Typical temperature reading sequence
Once all parameters have been set, the following sequence should normally be followed to extract
temperature information from your Neoptix thermometer. 2 procedures can be used for this purpose. The first
method consists in using the “ta” command (preferred), while the second sequence would be:

8 OPTILINK SOFTWARE PACKAGE
The OptiLink™ software package option allows using your thermometer system in a highly flexible manner.
The built-in functions allow for temperature displaying and data logging, as well as exporting to a variety of
standard spreadsheet packages.
8.1 The “Lite” vs. “Pro” version
OptiLink is now offered in two versions. The “Lite” version ships as a standard item with every Reflex
instrument. The “Pro” version includes more features and support more instruments and/or channels
simultaneously. Contact your Neoptix Representative or the Neoptix factory to buy an unlocking code.
8.1.1 Differences between the 2 versions
The “Lite” version exhibits the following limitations:
•
•
•
Only one instrument is supported (when scanning the COM ports (going from 1 to 32), the first
instrument that is detected by OptiLink becomes the active instrument).
Only 1 channel is supported.
No DDE temperature data logging is supported.
The remaining of this Chapter describes the “Pro” version.
8.2 Getting started with OptiLink
OptiLink was designed to acquire temperature readings from all models of the Neoptix Reflex thermometer
family. This versatile software package is designed to work with Microsoft Windows operating system; to fully
exploit the capabilities of OptiLink, it is recommended to use it in conjunction to commercial spreadsheet
software, such as Microsoft Excel.
8.2.1 Hardware and software requirements
The following list includes the minimum requirements for running the OptiLink software:
o
o
o
o
o
o
o
o
A Pentium class or higher CPU
SVGA or higher resolution display system supported by Windows
512 MB of RAM memory (operating system dependent)
At least 40 MB of hard disk space
A CD disk drive (to load software) (if requested, the software can be supplied on diskettes)
A mouse or other Windows pointing device
A RS-232 interface (COM1 to COM32). Up to 4 thermometer units are supported, each one
requiring its own COM port
Windows XP or later, including Windows-7 and -8 (Vista not recommended.
OptiLink works correctly with both half-duplex and full-duplex Neoptix thermometers. OptiLink is not
compatible with older Nortech-Fibronic thermometers and with Neoptix thermometers that have been
manufactured before August 2005.
8.2.2 Installing OptiLink
Before opening the CD and installing the software, please refer to the License and Limited Warranty
Agreement at the beginning of this manual.
You must have at least one, or more, properly installed Reflex thermometer unit(s). OptiLink should as well
detect other Neoptix thermometers, such as the Nomad, the T/Guard and even the T/Guard+ (in non-OPC
mode).

1- Start Windows, and make sure you are not running any other Windows program.
2- By inserting the CD in your computer, the SETUP application should automatically start; if not,
manually start it.
3- Follow the instructions that are displayed.
4- Restart your computer.
8.3 A quick tour of OptiLink
1- Connect your Reflex unit(s) to free COM port(s).
2- Start OptiLink, if not already running.
3- The thermometers that are turned on and connected to your PC through a proper RS-232
3
connection should normally be automatically detected by OptiLink (this process takes a few
seconds, for a typical installation).
4- If a thermometer is connected after OptiLink is started, you should click the “Refresh” button so
OptiLink rescans the COM ports (1 to 32). If a thermometer is not automatically detected, make sure
your RS-232 port and cable is correctly configured and that the unit is turned on.
NOTE: Some RS-232C connections may cause transmission failures. Particularly, we have
experienced problems with the use of DB09 to DB25 converters and other similar so-called gender
changers. Also, some USB to RS-232 converters/adapters are known to cause problems; Neoptix
recommends B&B converters ( http://www.bb-elec.com/Products/USB-Connectivity/USB-to-SerialConverter/In-line.aspx ); they are available from Neoptix. Limit your cable length to 10 meters.
You should normally see a window similar to this (acquisition window):
In this example, we see that OptiLink has detected 4 thermometers: a Reflex, a Nomad, a T/Guard, a
T/Guard-408, etc. (non-Modbus mode only, Modbus is not supported by OptiLink) and a T/Guard+ (in test
mode only; OPC mode is not supported by OptiLink).
OptiLink is now properly installed and ready to use!

8.3.1 Working with the Configuration Window
OptiLink starts with the “Acquisition” window (or pane) active, as shown in the figure above. To switch to the
“System Configuration” window, you need to click on one of the instrument names that have been detected;
for example, by clicking on “Reflex”, you will get the following window:
For each instrument, this configuration window gives some information about this particular information and
allows you to set some parameters.
The top portion of the window gives information about the specifics of the thermometer, such as:
• COM Port number
• Serial Number
• Calibration date.
Description of the parameters that can be set:
•
Unit: You can select C or F.
•
Scan Rate: Fast (recommended for most application) or Slow. .
•
Lock / Unlock Keypad: Can be selected to lock the keypad on the thermometer unit. Warning: once
locked, the keypad can only be unlocked through the use of OptiLink or with the “l-“ serial command.
o
o
Furthermore, for each channel, you can set the following parameters:
•
On / Off: You can turn on or off the temperature for each channel.
•
Name: Up to 16 characters. You can enter a probe name here that suits your application.
•
Log: If checked, the temperature data for this channel will be logged, when data logging is active.
•
Chart: If checked, the temperature data for this channel will be displayed when one of the 4 chart
windows is open.
•
Color: This is the color of the curve that will be used when the Chart window is open.

•
Alarms, Min and Max: Allows setting alarm limits. When one of more alarms are detected, a
message is given at the bottom of the main window (must be in Acquisition mode). For a given
channel, alarms are monitored only when its corresponding “Chart” or “Log” checkbox is checked, in
the Configuration window pane. Alarms are monitored only when Acquisition is active.
•
Analog Outputs: Allows configuring the analog output parameters, Zero and Span. See Section 6.4
for a complete description of these parameters.
•
Offset: Allows adding an offset to this channel. See below.
8.3.1.1
Adjusting a temperature offset
OptiLink allows you to add an offset to the temperature readings that are returned by a thermometer. This
feature is equivalent to the “f” serial command, as described in Section 6.4, although it implementation in
OptiLink is somewhat different than it is for the serial command.
An offset can be useful for the following two cases:
1- To temporarily change the reading of a probe that is believed to be in error (one-point calibration
procedure). This usually requires that a good temperature reference be available.
2- To force an offset to a reading, for example may want to monitor a temperature variation from a
given set temperature. In this case, you can simply enter the “0” value as a forced temperature
setting, and the resulting reading will give you a + or – deviation from the set temperature point.
Warning: Doing a temperature offset adjustment on a channel will alter its reading. In effect, it alters the
thermometer own calibration. It must be used with care!
To perform an offset adjustment, follow these instructions:
1- Click the “Offset Adjust” button (
) that is just next to the channel number you want to calibrate.
The following menu window is available:
2- Type in the “Set Point” box the actual temperature that you would like to force for this channel (this
temperature is normally obtained using an accurate NIST-certified primary temperature reference).
3- Press the “OK” button to activate the reference temperature. The “Offset” value will reset to its new
value, as a result of your new forced temperature; this new offset is now displayed in the main
window.
4- To reset this forced temperature setting, go back to the “Channel Offset” window, and click the Clear
button.
5- Repeat the same procedure for the other channels that you want to modify.
8.4 Acquiring and viewing temperature data
Once all your thermometers are properly connected and configured, you may want to log data to a file, or to
display their values on screen. A number of tools are available for that.
Document no. G1000r09

To view or acquire data, the “Acquisition” pane must be active.
8.4.1 Logging temperature data to a file
OptiLink offers the possibility to log temperature values to an Excel compatible file. The default file extension
is .tem; this file can be subsequently open using Excel, which should open it and automatically recognize as
an Excel compatible file (tab delimited).
Furthermore, OptiLink Pro offers the possibility to log directly to an .xls Excel file, using the Microsoft DDE
data transfer protocol. This is described in Section 8.4.1.2 below.
The parameters that are useful to control the logging are shown in the lower left portion of the window, as
shown here:
•
To set the logging filename, click on “SAVE AS…”; this allows you to enter a file name. For
information, the current filename is displayed just below this button. Default file location is “My
Documents”, for Windows 7 and above.
•
To set the acquisition rate, enter a number, in seconds, in the appropriate text box. Rate can be set
from 0.2 to 3600 seconds (1.0 to 3600 seconds if logging to an Excel file).
•
To start acquiring data, click the “START” button. Conversely, to stop the acquisition, click the
“STOP” button.
A convenient record counter is provided, confirming that logging is actually active.
8.4.1.1
Logging to a .tem file
When subsequently trying to opening the *.tem file, it is possible that you may get the following message:
Select “Select the program from a list”, and click OK. In the next window, you should instruct Windows to
always open this type of file with Microsoft Excel.
If you get the following message, you should select “Read Only”.

In Excel, the data file should look like this:
Notes:
1) If a column shows “#######”, this means that this column is too narrow to display the data; use
your mouse to widen this column.
2) If you open a logging file during acquisition, the Excel window is not refreshed as the
acquisition is taking place. To get a more recent version of the file, close the Excel program, and
start Excel again.
3) A value of -999.xx indicates that no reading is available for this channel. Check the probe
connection.
If you stop the acquisition, and start it again with the same file name, the new values will simply be appended
to the existing file content. However, a new 5-line header is inserted first, as shown here:
When logging temperatures for a very long time, one needs to note that a standard Excel sheet is limited to
65535 lines. If this limit is reached, the logging process will close the current data-logging file, and will open a
new one, with the same name but with “_1” appended to the file name, and so on (“_2” …), until the
application is stopped or your disk becomes full.
8.4.1.2
Logging to a .xls (or.xlsx) file
This logging method requires the Microsoft Excel application, which must be already installed. This logging
method has some advantages over the previously described logging method, namely:
• Temperatures are directly stored in a genuine .xls file; no intermediary file is used.
• It allows the user the look at the data as it is written in real time in the .xls file.
Document no. G1000r09

•
It allows the user to write comments directly in the .xls file, as the data is being acquired.
Warning: An English language Excel is required; logging using Excel in other languages may work, but is not
guaranteed by Neoptix. Furthermore, it is highly recommended that you do not use Excel for other purposes
when DDE data logging is taking place; failure to respect this may result in lost data (your data or
temperature data).
Before you can use this logging method, you must set it up on your PC. This needs to be done only once.
DDE logging setup
Click the DDE Excel checkbox, as illustrated here.
Then, you will get an invitation to specify the location of your Excel application (excel.exe). Once the Excel
4
location and language selection are confirmed (look into “C:\Program files\Microsoft Office\OfficeXX”),
logging will start as described below.
If you are using Office 2007 or later, make sure to check the box “.xlsx format”. With Office 2007 or later, files
can be saved only in the new format .xlsx.
DDE logging
Click the START button to start the logging process. The Excel application will open, and you will be able to
see the data being written to the file. Do not close this Excel sheet; however you may minimize it without
any problem.
To stop logging, click the STOP button in OptiLink; this will automatically close the Excel sheet and
application. Do not close the Excel application yourself!
Otherwise, the DDE logging is very similar to logging to a .tem file, as described above. Acquisition rate is
limited to 1 second.
8.4.2 Viewing temperature data
Temperature values can be displayed on your computer screen in a number of ways. Click one of the four
“Chart” button to active one or more of these windows.
4
You have two choices: English or French. If you are using Excel in another language, you must select
English.
Document no. G1000r09

29
Note that more than one window type can be displayed simultaneously; in addition, you can log temperatures
to a file independently from these display windows. Note that each of these 2 modes have each then own
acquisition time base.
8.4.2.1
Displaying temperature trends
Click the “Chart” button to get the following window.
Adjust the “Refresh Rate” (minimum is 0.2 sec) and Min / Max to suit your viewing needs.
Note that the setting of curve colors and other parameters must be done in the “System Configuration”
window pane. Up to 64 trends can be displayed.
8.4.2.2
Displaying analog thermometers
Click the “Thermo” button; the following window will appear.
All thermometers share the same Min / Max reading setting. Refresh rate is fixed at 1.0 sec. The size of this
window will change depending on the number of channels to display. Up to 16 thermometers can be shown;
if you want to display more than 16 channels, only the first 16 detected channels will be shown (note that any
channel that has its “Chart” checkbox unchecked, in the main window, will not be shown).
If an alarm is active for a channel, the corresponding thermometer numbers will change color: blue for a low
temperature alarm, or red for a high temperature alarm.
8.4.2.3
Displaying digital values
To display digital temperatures, click on the “Digital” button. The following window will appear.
Document no. G1000r09
Copyright Neoptix Canada LP
30
The size of this window will adapt to the number of channels to display. Up to 32 values can be shown.
Refresh rate is always 1.0 sec.
If an alarm is active for a channel, the corresponding display will change color: blue for a low temperature
alarm, or red for a high temperature alarm.
8.4.2.4
Displaying analog values (dials)
To display analog temperatures (using dials), click on the “Analog” button. The active window becomes this:
All dials share the same Min / Max reading setting. Refresh rate is always 1.0 sec. The size of this window
will adapt to the number of displayed channels. Up to 16 dials can be shown; if you want to display more than
16 channels, only the first 16 detected channels will be shown (note that any channel that has its “Chart”
checkbox unchecked, in the main window, will not be shown).
If an alarm is active for a channel, the corresponding dial numbers will change color: blue for a low
temperature alarm, or red for a high temperature alarm.
8.5 The OptiLink Console
You must be in “System Configuration” mode to use the console.
The console, which can be invoked through the Window and then Open Console from OptiLink main window
menu bar, is useful to manage each Neoptix thermometer in details. Take note that the console can only be
open when no temperature acquisition is taking place. It can be useful also to understand problems and
malfunctions that a module may exhibit. It operates in a similar fashion as Windows HyperTerminal, which
Neoptix suggests to use with all thermometer models (such as the Reflex or T/Guard).
The console can be used to get information such as:
•
Information on calibration date, serial number, etc.
•
Enable / disable channels
•
Set the analog output parameters (zero and span)
•
Control operational features, such as fast/slow scanning more, wtune, etc.
•
Calibration type, Neoptix or Nortech Fibronic, Inc.

•
And so forth.
The following illustrates the OptiLink Console:
Before sending commands and receiving information from a specific module, it is necessary to select the
instrument you want to interrogate. Please note that only ONE instrument can be selected at a time; if the
same command is to be sent to all thermometers, then, it is necessary to repeat the command for each
individual thermometer.
You can use “Copy and Paste” Windows commands (such as the following shortcuts: ctl-c and ctl-v) to copy
selected content of the console content to other Windows programs, such as Notepad, or e-mail program,
etc.
8.5.1 Console help menu
The following is the menu as displayed by the instrument when sending the “h” command. This help menu
can be used as a reminder of all available commands, for this specific instruments.
For a complete description of all commands, refer to Section 6.4 above.
