INTRODUCTION
The ENVIROMUX-MINI-LXO (ENVIROMUX) are Server Environment Monitoring Systems designed to monitor, from a remote
location, the critical environmental conditions in cabinets and rooms containing servers, hubs, switches and other network
components. Remote monitoring is provided via a 10/100BaseT Ethernet web interface,secure web interface, SSH, or Telnet.
The input data is filtered, collected, analyzed and processed to allow the user to configure it to meet individual requirements. The
user is able to specify parameters for all monitored signals. When a sensor exceeds the configured threshold, the unit will signal
an alert. Alert methods include email, SMS, SNMP traps (MIBs), web-page alerts, and a visual indicator (red LED).
The ENVIROMUX-MINI-LXO will monitor temperature, humidity, and detect the presence of water on a flat surface (such as the
floor). The unit also has four sets of terminal block pairs for the connection of contact-closure sensors.

INSTALLATION
Connect Sensors
Connect the desired sensors (sold separately) to the available ports on the ENVIROMUX. Plug the RJ45 connectors to either of
the two RJ45 ports marked "TEMPERATURE/HUMIDITY". Mount the sensors according to their individual operating
characteristics. Power-cycle the ENVIROMUX after sensors have been plugged-in.
Note: The maximum CAT5 cable length for attachment of temperature and humidity sensors in the
ENVIROMUX-MINI-LXO is 25 feet.
Note: Mounting the temperature sensor in the path of a fan or on a heated surface may affect the accuracy of the
sensor’s readings.
Figure 1- Connect Sensors
Up to five dry-contact sensors can also be connected. Sensors with 16-26 AWG connection wires, that operate on 5V at 10mA
maximum current may be used. A contact resistance of 10kΩor less will be interpreted by the ENVIROMUX as a closed contact.
The maximum cable length for attachment of contact sensors is 1000 feet.
To install the dry-contact sensor(s) to “DIGITAL IN” terminals:
A. Attach the positive lead to a terminal corresponding to a "+" marking on the ENVIROMUX and the ground lead
to the next terminal to the right that will correspond to a marking on the ENVIROMUX. Tighten the set
screw above each contact. Terminal sets are numbered 1-5.
B. Mount the sensors as desired.
Figure 2- Terminal block for dry-contact sensors
Note: The terminal block is removable for easy sensor wire attachment if needed.

Optionally, connect the two-wire cable from a liquid detection
sensor (ENVIROMUX-LD shown below- sold separately) to a set
of “DIGITAL IN” contacts.
The twisted orange sensing cable should be placed flat on the
surface (usually the floor) where liquid detection is desired. If
tape is required to hold the sensor in place, be sure to only apply
tape to the ends, exposing as much of the sensor as possible. At
least 5/8" of the sensor must be exposed for it to function. (See
Figure 3)
Figure 3- Secure liquid detection sensor with tape
To test the ENVIROMUX-LD;
1. Configure the sensor (page 26). (Normal Status set to “Open”, Refresh Rate set to 5 seconds.)
2. Submerge at least ½ inch of the exposed twisted orange wire (not the wrapped end) for up to 30 seconds. Do NOT use
distilled water as water must be conductive.
3. Monitor the sensor (page 20) to see the sensor “Value” change from “Open” (dry) to “Closed” (wet).
4. Dry the exposed area of sensor and the sensor “Value” should change back to “Open” within 30 seconds.

Output Relay
An output relay is provided to control an external device with a rating of up to 1A, 30VDC or 0.5A, 125VAC. Three terminals are
provided to enable a normally-open connection (using the N.O. and C terminals) or a normally-closed connection (using the N.C.
and C terminals). Using the web interface, this relay can be set to change state (close the normally-open connection, or open
the normally-closed connection) either manually (page 29) or as a result of an alert state from one or more of the connected
sensors (page 22). The terminals for these connections will accept 16-26AWG wire.
Figure 5- Output Relay Application Examples
Ethernet Connection
Connect a CAT5 patch cable (RJ45 connectors on each end wired pin 1 to pin 1, pin 2 to pin 2 etc) from the local Ethernet
network connection to the connector on the ENVIROMUX marked "Ethernet".
Figure 6- Connect ENVIROMUX-MINI-LXO to the Ethernet
Note: A direct Ethernet connection can be made with a PC using a crossover cable. For the pinout of this cable, see
page 102.
Note: A recent design improvement
resulted in a change to the pinout of
the output relay in the ENVIROMUX-
MINI-LXO. Please be aware of the
change and note which version yours
is. The previous version is shown
below.

USB Console Port
Your ENVIROMUX includes a USB Type B connector labeled “USB Console”. If you connect a USB cable between the
ENVIROMUX and your PC you will be able to control your ENVIROMUX serially from a terminal console using this connection.
Figure 7- Connect terminal to USB Console port
Installing Drivers
You will only need to install drivers the first time the ENVIROMUX is connected to your PC. After the first time, when the
ENVIROMUX is connected, your PC should recognize the ENVIROMUX and re-assign the COM port. Follow the steps below to
install the drivers.
1. Make sure the USB cable is connected between the ENVIROMUX and your PC.
2. Power ON the ENVIROMUX. The PC will see the ENVIROMUX as “New Hardware” and create a virtual COM port to
communicate with it.
3. You will be prompted to load drivers. A driver file compatible with Windows XP, 2000, Vista and 7 (32 and 64 bit versions) can
be found on the CD that came with your ENVIROMUX. Browse to the drive your Product Manual CD is in and locate and select
the file named “enviromux.inf” in a directory named “windows-drivers\32bit or \64bit” depending upon your
operating system.
The .inf file will direct your PC to locate and install the file usbser.sys (already on your PC, comes with Windows). Installing
the usbser.sys file should happen automatically. When finished, Windows will indicate installation is successful.

Windows XP-32 bit Installation
Your typical installation will include windows like the ones that follow. The images below are from a Windows XP SP2 32 bit
installation.
A
. Windows will want to check the internet
for drivers. Choose “No, not this time”
because the drivers are unique to the
ENVIROMUX.
B. You can try to “Install the software
automatically” but if windows doesn’t check
the CD, you will need to use “Install from a
list or specific location” instead.

C. Let the New Hardware Wizard search for
the driver, but direct it to the drive the Product
Manual CD is in and the directory of either
the 32 bit driver or the 64 bit driver.
D. Once the driver is installed, you will get
this screen and the ENVIROMUX USB
Console Port will be ready to use.

2. Use the NTI Discovery Tool (page 17) to configure network settings.
Front Panel LEDs Indicate Status
With proper connections made, the ENVIROMUX is now ready to power ON. With the power cord attached and plugged into an
AC outlet, the “Power” green LED should be illuminated on the front of the ENVIROMUX. The red “Fault” LED will illuminate
when power is first applied and while the ENVIROMUX boots up (for up to 60 seconds). Once the red LED goes OFF, the
ENVIROMUX is ready for use. After a completed boot-up, the red LED will only illuminate when one of the connected sensors is
in alert.
