Please see the below picture: (2) SRWF-102 provides TTL interface. Figure 2 TTL connection diagram Note: please don’t connect any wire on PIN6 and PIN7 to avoid interference. (3) Interface rate setting The rate of SRWF-1021 is determined by hardware and software, to make sure the module rate is suit to your system. __________________________________________________________________________________ Tel: +86-021-38953738/38953768-840 Fax: +86-021-50270187 http://www.sunrayrf.com Address: No. 498 Guoshoujing Road. Pudong Zhangjiang, ShangHai 201203, China Shanghai Sunray Technology Co., Ltd (4) SRWF-1021 can support no parity and even parity mode of the serial communication UART, it can chose parity mode through E of J1. E=0 (without jumper) even parity 9N1 E=1 (with jumper) no parity 8N1 (5) Timing Diagram 1. The PIN8 ‘SLP’ in CON1 is the signal of sleep control. In low power level, when the transceiver stays in sleep mode, the conversion from idle mode to sleep will be finished in 6ms. If the sleep signal arrives when the transceiver is transmitting, the module will enter sleep mode after finishing transmission. From sleep mode to transceiver mode, it takes when the RST signal comes. 2. The delay time (TC) of conversion between transmitting and receiving is less than 3ms. The delay time of transceivers between the first sent by TXD to the first bit received by RXD. Due to a processing will be made on user’s command by SRWR-1021 transceiver using FEC(Forward Error Correction) or other correction algorithm, when RXD of a SRWF -1021 transceiver ‘A’ receives the command, then transmits it, the other one transceiver ‘B’ will have a delay(Td) to receive and transmit by TXD. Different RF command rate causes different delay __________________________________________________________________________________ Tel: +86-021-38953738/38953768-840 Fax: +86-021-50270187 http://www.sunrayrf.com Address: No. 498 Guoshoujing Road. Pudong Zhangjiang, ShangHai 201203, China Shanghai Sunray Technology Co., Ltd time. Please see the delay time below: (6) Indicator function When transmitting mode, the red indicator light will twinkle. (Only UART TTL) When in receiving mode, the green indicator light will twinkle (Only UART TTL). (7) TX light will flash once when the module is powered on, meaning that the module is sending to serial port its version information by which we can judge some basic status about the module, for example: SRWF-1021（V11） C=00（433），9N1 Illustration：SRWF-1021 is module model， （V11）indicates that module software version is V1.1 C=00(433), 00 means channel No., and 433 is carrier frequency. 8N1/9N1 means check mode.
