RADIOMETRIX TDL2A-433-9 收发器, UHF数据
is a 9600 baud half-duplex multi channel OEM radio modem in BiM2 footprint operating at 433.925 - 434.565MHz frequencyEuropean ISM frequency band . TDL2A-433-9 acts as a transparent serial cable to attached host. TDL2A-433-9 is an intermediate level OEM radio modem which is in between a raw FM radio module like BiM2 and a sophisticated OEM radio modem like SPM2. TDL2A-433-9 will take care of preamble, synchronisation, bit balancing and error checking along with automatic noise squelching when there is no transmission. The TDL2A provides a half duplex link. Provided no two devices attempt to transmit simultaneously no further restrictions on data transmission need be made. Includes all transmit timing, valid data identification and datastream buffering is conducted by the unit. For multiple radio systems a TDL2A can be set to 1 of 8 unique addresses. As well as having unique addresses, The TDL2A allows operation on one of 5 pre-set frequencies in the 433MHz band.
