Product Overview
Monitor
The Model U Universal Monitor is designed to monitor a variety of
extreme temperatures from one device. Equipped to accommodate from
four to sixteen temperature ports (Models U4 and U16 respectively), it
can be installed and running in minutes.
Designed with flanges for wall or rack
mounting, the lightweight device
measures a compact 4¼” x 3¼” x 1⅜”
(10.8cm x 8.3cm x 3.49cm) and weighs
about 0.35 pounds.
Probes are available separately to allow
you to purchase ust what you need according to the number of units that
you are monitoring. The Model U is specifically designed to be used with
our food-piercing and high temperature probes, and can also be used
with our standard temperature probes and our cryo low-temperature
probes.
Probes
The food-piercing and high temperature probes measure temperatures
from -30°F to 572°F (-34°C to 300°C) and are supplied with a 3’ cable,
stainless steel sensors, and are appropriate to measure anything from
hot water to cooked foods; longer
cables are also available.
In addition to the high
temperature probe, you can use
the standard or heavy-duty
temperature probes used with the
Model E; and the cryo low-
temperature probes used with the
CM16.
The standard probe has a 50-foot, 24-gauge AWG cable with the sensor
housed in a small, white nylon cap (0.325” diameter, 0.575” length). It is
appropriate for most indoor applications.

Configuring the Device
Before you can use the Model U Universal Monitor, you must either
determine a static IP address, network mask and gateway that is
available on your network, or set the unit to DHCP mode. The address
received in DHCP mode can be determined by connecting to the RS-232
serial port.
Step 1. Configure the RS-232 ports
Start a terminal emulator program (such as HyperTerminal included with
MS Windows).
a. Set the RS-232 port settings as shown:
Bits per second: 9600
Data bits:
Parity: None
Stop bits: 1
Flow control: None
Note: If the settings are
incorrect, the device will not
be able to communicate with
your terminal emulator.
b. Ensure that the power cord ack is connected to the Model U
Universal Monitor and the wall transformer is plugged into a powered
outlet.

you to view the overall stability and well-being of your temperature-
controlled units from a single Web-based interface. Our software,
coupled with our high-quality monitoring devices provides you with a
complete monitoring, notification and trending analysis solution without
having to invest in a complex infrastructure.
SEMS is comprised of three basic components: the temperature
monitoring devices and probes, which monitor activity from a particular
unit and then send data to the software application; the software
application tracks utilization and compares the reported data against
thresholds that you define, then broadcasts the status, including alerts
and alarms; and a Web-based graphical user interfaces which display
the results in an easy to read format that allows any (or all) of your staff
to easily view the overall status of your environment – or even to receive
immediate alerts to a pager, cell phone, or text messenger for
catastrophic failures.
Contact us for a real-time, online demonstration. Call [phone] to
schedule an appointment with one of our SEMS Sales Managers.
SNMP
SNMP Version 1.0 is supported in the Model U series of temperature
monitors. The latest MIB files are available via our website at:
http://www.sensatronics.com/downloads/snmp.
To set the SNMP community strings, use the serial port configuration
menus from Step 2, and press C .
Note: When configuring the SNMP community strings (read, read/write,

Write Your Own
The Model U Universal Monitor runs an internal Web server that listens
for TCP/IP HTTP /GET requests on Port 80, and responds to five
different URL requests – /index.html, /xmldata, /xmlconfig, /data and
/config.
/index.html: This is the main index page that returns an HTML-
formatted Web containing the temperatures of all connected
probes. This index page also provides details about the
Temperature Monitor such as manufacturer, serial number, unit,
and probe names.
/data: This request will return an HTML-free Web page,
consisting of a simple ASCII string of pipe-delimited data.
The data will be in the format of
“Temp mode|Group 1 temp|Group 1 Humidity|Group 1 Wetness|Group 2 Temp…”
This URL is typically used by OEMs who are packaging the
Temperature Monitor for use with their own software and need
an easy and efficient way to get at the probe temperature data.
This URL is also handy for those wishing to write their own
software interface to simply and quickly obtain the temperatures
and incorporate them into their existing Network Management
Software.
Here’s an example:
F|70.9|46.0|67.8|-999.9|-999.9|75.7|69.9|-999.9|-999.9|222.6|-
999.9|-999.9
/config: This request will return an HTML-free Web page,
consisting of a simple ASCII string of pipe-delimited data. The
information contained in this string of data will include
configuration information about the Temperature Monitor such as
serial number, unit and probe names, and model number.
Here’s an example:
EM00000000|EM1|Model U|12|4.1|1|Server
Room|T|Temperature| | umidity|W|Wetness|2|Group
2|T|Temperature| | umidity|W|Wetness|3|Group
3|T|Temperature| | umidity|W|Wetness|4|Group
4|T|Temperature| | umidity|W|Wetness
