3.Saving power model
FY-602 have three Power-Saving models: Awaken from Hardware, Awaken from COM Port, Awaken
from Air. The model can be set by RF Module software. The user can choose Power-Saving model, the default
model is “Awaken from Hardware”.
1) Awaken from Hardware:
In this model, the current is under 100uA.
Sleeping status: when you input low level at NO. 5 pin, FY-602 can sleep, but it can not transmit and
receive data.
Normal work status: when you input High level at NO. 5 pin, FY-602 turn into Normal work status, 10ms
later, it can transmit and receive data.
Remarks: if you keep the NO. 5 pin untouched, then FY-602 is in Normal work status.
2) Awaken from COM Port:
When FY-602 in this model, the current is under 11mA.
When you input data with COM port, FY-602 turn into Normal work status after 10mS and can transmit
the data.
When FY-602 not receive data in COM port in 20 seconds , FY-602 will turn into sleep status.
3) Awaken from Air:
In this model, the current is under 20mA.
When in this status, FY-602 works intermittently.
When FY-602 received data from air, FY-602 will turn into Normal work status after 10ms, It can receive
data normally.
When FY-602 not receive data from air in 20 seconds, It will turn into sleep. So when you choose
Awaken from Air, you can transmit some useless data firstly.
FY-602 parameters setting
The interface of FY-602 is TTL.
FY-602 main parameters: COM baud rate and verify，RF baud rate, Channel and frequency.
You can change these parameters by our RF Module soft. When RF baud rate is faster than COM baud
rate，One frame Can transmit limitless data. When RF baud rate is not faster than COM baud rate ，One frame
Can transmit 255 bytes most. You can set the rate according your need.
The general Power supply is 5V DC.
Two FY-602 communication must have condition as follow:
1. Their channels (i.e. frequency) are the same.
2. Their RF rates are the same.
3. RF Module Com baud rate and verify is comply with its equipment or PC.
Parameters default value:
Channel： 5
Interface speed rate：19200BPS
Interface verify：none
Speed rate in air：19200BPS
