5.Setting of channel, interface, and data format

The user can change or view the module's interface baud rate, channel and address code.

Parameter setting or reading as per the testing software "YSPRG.EXE" in the CD (in products box) .

Channel No.	Frequency	Channel No.	Frequency	Channel No.	Frequency	Channel No.	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.
