Why is the wireless data logger not appearing in the software?
If the VTMS doesn’t appear in the Connected Devices panel, or an error message is received while using the VTMS,
try the following:
• 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, try switching the battery with a new 9V lithium.
• Ensure that the MadgeTech 4 Software is being used, and that no other MadgeTech Software (such as MadgeTech 2,
or MadgeNET) is open and running in the background. MadgeTech 2 and MadgeNET are not the compatible with the
VTMS.
• 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.
• Ensure that 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.
Troubleshooting wireless transceiver problems
Check that the software properly recognizes the connected RFC1000 wireless transceiver.
