RADIO
RM8003-03
TRANSCEIVER
The compact Radio
RM8003-03
900MHz transceiver replaces miles of cable in harsh industrial environments. Using
field-proven FHSS technology, which needs no additional FCC licensing in the Americas, OEMs can easily make
existing systems wireless with little or no RF expertise.
OVERVIEW
The Radio
RM8003-03
is a cost effective, high performance, frequency hopping spread spectrum (FHSS) transceiver
designed for integration into OEM systems operating under FCC part 15.247 regulations for the 900 MHz ISM band.
Radio
RM8003-03
transceivers operate in a Masterless architecture. The Radio
RM8003-03
instead uses a Timekeeper
to synchronize the network. The Timekeeper can be selected manually or the network can use built in a.i. to pick a
timekeeper. Timekeeper can act as a pseudo gateway in order to synchronize signals or devices can communicate
directly to one another when synchronization is not necessary.
All Timekeeper devices broadcast an RF sync pulse on periodic intervals along with timing information for secondary io
beacons that are pulsed on a digital output line.
Serial data will be routed according to the destination serial number.
Digital input signals will be broadcast and then synchronized on the timekeeper pulses.
To boost data integrity and security, the Radio
RM8003-03
uses FHSS technology with data whitening and 16bit CRC
data integrity checks. Configuration data is stored in an on-board EEPROM.
All frequency hopping, synchronization, and RF system data transmission/reception is programmed in the factory and
is performed by the transceiver, transparent to the OEM host.
The manufacturer is responsible for ensuring the final product meets all appropriate regulatory agency requirements
listed herein before shipping any product.
The integrator is responsible for meeting the requirements of KDB 996369, D04.
The integrator should contact TAPCO for information regarding test mode
s
or configuration options.
