6. Setting of channel, interface, and data format: The user can change or view interface baud rate, channel and address code. Parameter setting or reading as per the testing software "SPRG.EXE"in the CD (for free) come with the products. | Channel | Frequency | Channel | Frequency | Channel | Frequency | Channel | Frequency | | 1 | 429.0325MHZ | 2 | 430.0325MHZ | 3 | 431.0325MHZ | 4 | 432.0325MHZ | | 5 | 433.0325MHZ | 6 | 434.0325MHZ | 7 | 435.0325MHZ | 8 | 436.0325MHZ |
NOTE: Generally the module in receiving state, if the IDLE pin continuously connect low level (>200millisecond), the module will be in sleep state, at the same time the module can not receive or transmit any data, only when the IDLE pin hang or in the state of high level (VH<3.5V), the module can be in receiving state again. |
