DR-915L Data Radio
General Information and Labeling Requirements
This DR-915L is a data transceiver operating in the 902-928 MHz ISM band. The unit is
designed to operate under Part 15.249 of the FCC rules and regulations and is designed
as an OEM module for professional integration into other products or field devices.
When installed using an approved antenna, the user need only ensure that the
appropriate FCC information is clearly visible on the outside of the integrated product.
This label should contain one of the following phrases to be considered valid.
1. "Contains Transmitter Module FCC ID: PHO-CDR915L" or
2. "Contains FCC ID: PHO-CDR915L"
Caution: If this radio is integrated into another product, the user is responsible for
complying with the external labeling requirements as directed in the FCC Rules and
Regulations part 15.19. To avoid the need to obtain additional FCC certification, the
user should only use antennas that have been tested and approved for use with this
radio module.
The unit operates on 62 discrete frequencies within the ISM band, each frequency
about 400kHz apart. Using a frequency agile phase-locked loop synthesizer, the radio is
able to operate on any of 62 non-interfering channels.
The radio is connected to a host device using a 10-pin SIP header. This connection
provides the radio with the required DC power source, allows it to be programmed and
configured and provides all I/O lines for both an asynchronous serial as well as an SPI
interface.
