I. Introduction
SRWF-RFScanner-SDK transceiverdatamoduleofwirelessscanner transmitthe
codingdatafromscannerbywireless towireless receiverterminal. Ithaswireless transmit、
carrierdetect、verification、lowvoltagealarm, guaranteeingtheconvenience andveracityof
datatransmit.modulewillbeinsleeping modewhennotreceiving datafromscannerinthe
enactmenttime, andcouldbewakebyswitch.
II.Feature
Lowpowertransmission: Withthetransmissionpowerof17dBm,carrierfrequencyof
433MHz
Multi-channel: Thestandardconfigurationprovides8channels,meetingthemultiple
combinationalmodeofcommunication.
Highanti-interference and lowBER(BitErrorRate): BasedontheGFSK/FSK
modulationmode, carryontheverificationtotheeachpackageofdata,guaranteeing
theaccuracy.
Lowpowerconsumptionandsleepingfunction: themodulewillbeinsleeping mode
