1.Therefore, proper program design of sequence and cycle control should notice as follows:make I/O point、coil of relay of auxiliary point and act principle and act condition of TIM definite;
2.The system adopts the Direct Sequence Spread Spectrum (DSSS) and Complementary Code Keying (CCK) modulation technology, works on Frequency Division Dual (FDD) mode and uses the 2.4~2.7835GHz ISM frequency. It can relay the 5×E1 multiplexed signal.
