Introduction
The VSUB235 is an RF transceiver module. It interfaces with other
equipment using standard serial asynchronous communications protocol at a rate
between 9600 and 57600 baud. The transmitter has a peak output power of
123mW. It is designed to be incorporated into control devices developed by
Vantage Controls. The module operates under FCC approval in the 902-928
MHz ISM frequency band.
Integrating the VSUB235 into Products
IMPORTANT: The VSUB235 radio has been certified by the FCC as a module
for integration into products without further certification being necessary (as per
FCC section 2.1091.) The following requirements must be satisfied in order to
comply with FCC regulations:
1) The system integrator must ensure that the external label provided with
this device is placed on the outside of the final product.
2) In order to comply with the FCC RF exposure requirements, the
VSUB235 may be used only with the antennas it was certified with:
