Quick Start Steps
Product Overview
The MadgeTech RFOT is a two-way wireless meat cooking and cooling data logger. The
RFOT’s rugged design, equipped with a flexible piercing probe allows it to be used in harsh
environments. The RFOT is perfectly suited for use in smokehouses, ovens and other cooking
processes up to 212 °F (100 °C) as well as refrigerators and freezers down to -4 °F (-20 °C). The
RFOT is completely splash-proof, and can withstand wash down cycles. The RFOT records and
wirelessly transmits internal product temperature readings back to a central PC for instant
real-time monitoring, even when a smokehouse or freezer door is closed. The RFOT allows the
user to also set-up real-time wireless alarming within the soware, so that the user is notified by
email or text if an alarm condition has been met or exceeded. The RFOT assists in complying with
HACCP requirements as well as USDA regulations.

RFOT
1. Connect the RFC1000 wireless transceiver (sold separately) to the Windows PC with the
provided USB cable.
2. Additional RFC1000’s can be used as repeaters to transmit over greater distances or to
maintain signal if walls, corners, or other obstacles impede line of sight. Plug each one into
an electrical outlet in the desired locations.
3. Launch the MadgeTech 4 Soware.
4. The RFOT is shipped with wireless transmission
in an active, low power state. Inserting a USB
(micro B type) cable into the RFOT enables
direct USB communication and disables wireless
transmission. Direct USB communication allows
for changing the wireless channel in the device’s
Properties, if necessary.
5. When the USB cable is unplugged, wireless transmission is enabled.
6. All active data loggers will be listed within the Connected Devices panel. Select a logger,
and click the Claim icon to pair the logger to the RFC1000 connected to the PC.
7. Choose the start method, either Real Time Start to view data as it is collected, or Custom
Start for standalone logging to memory. By default, a report is generated automatically
when starting a logger using Real Time Start. With Custom Start, data is recorded to
memory and can be viewed by selecting Stop to end the cycle, and Download to retrieve
the data from the logger’s internal memory.
Activating & Deploying the Data Logger
Mounting Instructions
For best performance, the RFOT should always be hung by the hook in an
upright position. This will allow for the best path for the wireless signal.
Transmission Distance
Typical transmission distance from an RFC1000 to an RFOT:
»Unobstructed line of sight (outdoors): 2,000 feet max
»Typical urban environment (indoors): 500 feet max
Obstacles
Obstacles will decrease the line-of-sight from an RFC1000 to another RFC1000 as well as from an
RFC1000 to an RFOT. Obstacles that interfere with or decrease the wireless signal could include
but are not limited to smokehouse doors, freezer/refrigerator doors, building structures such as
walls and metal beams and internal traic such as forklis and metal racks or carts. Additional
RFC1000's can be placed near obstacles to lengthen and strengthen the wireless signal.
Deflection
When a wireless signal “hits” an object such as a metal wall, the wireless signal will not just
stop but rather it could turn a corner, bend or slow down. When installing the RFC1000's
obstacles and possible deflection should also be considered.
For steps to claim the data logger and view data using MadgeTech Cloud Services, refer to the
MadgeTech Cloud Services Soware Manual at: madgetech.com/mt-cloud-manual.pdf

Dierent wireless channels may be used to create multiple networks in one area, or to avoid wireless
interference from other devices. Any MadgeTech data logger or RFC1000 wireless transceiver that
is on the same network is required to use the same channel. If all of the devices are not on the
same channel, the devices will not communicate with one another. MadgeTech wireless data
loggers and RFC1000 wireless transceivers are programmed by default on channel 25.
Changing the channel settings of the RFOT
Connect the RFOT to MT4 with a USB cable. Select a device from the connected devices
window, then click the properties icon at the top of screen, or, right click on a device in the
connected devices window and select properties. On the properties screen, select Wireless
and in the Wireless Channel box, click the down arrow, then the desired channel. Click OK to
confirm the choice.
Be sure that the channel chosen matches the channel settings of the RFC1000 wireless transceiver
which this device will communicate through.
To configuring the channel settings of the RFC1000 wireless transceiver (sold separately),
please refer to the RFC1000 Product User Guide that shipped with the product or download it
from the MadgeTech website at madgetech.com.
Channel Programming
CHANNEL NOTE: MadgeTech wireless data loggers and wireless transceivers purchased prior to
April 15, 2016 are programmed by default to channel 11. Please refer to the Product User Guide
provided with these devices for instructions to change the channel selection if needed.

Troubleshooting
Why is the wireless data logger not appearing in the MadgeTech 4 Soware?
If the data logger doesn’t appear in the Connected Devices panel, or an error message is received
while using the data logger, try the following:
»Ensure the data logger and RFC1000 are on the same wireless channel. If the devices are not on
the same channel, the devices will not communicate with one another. Please refer to the Channel
Programming section for information on changing the device channel.
»Check that the RFC1000 is properly connected. For more information, see Troubleshooting
wireless transceiver problems (below).
»Ensure that the battery is not discharged. For best voltage accuracy, use a voltage meter
connected to the battery of the device. If possible, replace battery.
»Ensure that the MadgeTech 4 Soware is being used, and that no other MadgeTech Soware
(such as MadgeTech 2, or MadgeNET) is open and running in the background. MadgeTech 2 and
MadgeNET are not the compatible with the RFOT.
»Ensure that the Connected Devices panel is large enough to display devices. This can be verified
by positioning the cursor on the edge of the Connected Devices panel until the resize cursor
appears, then dragging the edge of the panel to resize it.
