rc11xx-rc232 ? 2010 radiocrafts as rc11xxrc232 data sheet (rev. 1 .43) page 5 of 24 radiocrafts embedded wireless solutions block diagram circuit description the module contains a communication controller with embedded rc232? protocol software, a high performance rf transceiver and an internal vol tage regulator. the communication controller handles the radio pack et protocol, the uart interface and controls the rf transceiver. data to be sent by the host is received at the rxd pin and buffered in the communication controller. the data packet is then a ssembled with preamble, startofframe delimiter (sof), address information and crc check sum before it is transmitted on rf. the preamble and sof is always used. the address and cr c are optional. the rf transceiver modulates the data to be transmi tted on rf frequency, and demodulates data that are received. received data are checked for correct address and c rc by the communication controller. if the address matches the modules own address, and no crc errors were detected, the data packet is sent to the host on the txd line after removing the header. the asynchronous uart interface consists of rxd and txd. optionally cts, rts can be used for hardware handshake flow control. rxtx can be us ed to control the direction of an rs485 driver circuit. when the config pin is asserted the communication c ontroller interprets data received on the rxd pin as configuration commands. there are comman ds to change the radio channel, the output power, the destination address etc. permanen t changes of the configuration is also possible and are then stored in internal nonvolati le memory. the rf protocol and the configuration commands are described in detail in the rc232? user manual. the supply voltage is connected to the vcc pin. the module contains an internal voltage regulator and can therefore operate over a wide sup ply voltage range. gnd cts rts config txd rxd gnd communication controller gnd vcc reset nc gnd rf gnd voltage regulator rf transceiver www.datasheet.co.kr datasheet pdf - http://www..net/
rc11xx-rc232 ? 2010 radiocrafts as rc11xxrc232 data sheet (rev. 1 .43) page 6 of 24 radiocrafts embedded wireless solutions rc232? embedded protocol the module offers a buffered packet radio in the rc 232? embedded protocol. using the buffered packet radio mode, all data to be sent is stored in the module before they are transmitted by the rf circuitry. likewise, when data is receive d they are stored in the module before they are sent to the host. this allows the communication con troller to add address information and to do error check of the data. in buffered mode the uart interface is used to communicate with the host. the embedded protocol, configuration commands and c onfiguration memory is described in the rc232? user manual. this protocol is used in a wide range of rf modules available from radiocrafts. please refer to the latest revision av ailable on radiocrafts website. power management the module can be set in sleep mode in order to red uce the power consumption. when the sleep pin is not enabled (rf_sleep_mode = 0x00) the module can be set in sleep mode by activating config and sending a z command . the module is woken up when config is deactivated (goes high). note: during sle ep the config pin does not have any internal pullup, so the config pin must be driven high in order to wake the module. any activity on the rxd pin will make the module wake up, but im mediately return to sleep as long as config is kept low. such activity on the rxd pin sh ould be avoided in order to reduce current consumption. when the sleep pin is enabled (rf_sleep_mode = 0x02 ) the module can be set in sleep mode by activating rts/sleep (asserting low). the m odule is woken up when rts/sleep is deactivated (goes high). note: during sleep the rts /sleep pin does not have any internal pull up, so the rts/sleep pin must be driven high in ord er to wake up the module. any activity on the rxd or config pins will not make the module wak e up. activity on module pin 16 and 17 can wake the module and must be avoided (do not con nect, as previously stated in this document). config must be high when awakening the m odule to avoid setting the module directly in configuration mode. all configuration settings and ram values are retai ned during sleep. the pullups on rts/sleep and config pin are disabled during sleep mode in or der to minimise the sleep current consumption. if the module is shut completely off, all configuration settings in nonvolatile memory is restored, but values in ram are overwritt en with default settings. idle sleep idle mode rts/sleep enter sleep mode using rts/sleep pin idle sleep idle mode config enter sleep mode using config and z comand uart comand z config www.datasheet.co.kr datasheet pdf - http://www..net/
