The model T9, 900 MHz radio modem, and model T24, 2.4 GHz radio modem,
provide the features and performance of FreeWave’s standard 900 MHz and 2.4
GHz products in a package designed specifically for use in traffic signal control
applications. The T-Series radios install in a single card slot in any standard loop
detector card rack. Both models draw their operating power from the card rack
interface connector but otherwise do not make any connection with the card rack.
All data I/O and antenna connections are made to the radio’s front panel
connectors. See Figure 1.

To operate a T-Series radio modem, insert the radio into a loop detector card
rack as shown in Figure 2. Make certain that the radio is fully seated in the card
slot. When a proper connection to the card rack has been made, one or more of
the LED status indicators will light. The LED indicators will show different
displays depending on how the radio is programmed when it is installed into the
card rack.

compatible with FreeWave’s FGR-Series 900 MHz radio modems or I-Series 2.4
GHz radio modems and may be used in networks with any of these products.
The T-Series radios will not communicate with radios that are not manufactured
by FreeWave Technologies.
