5. Installation dimension:
6. The Function-indicator light
a. The LED indicator light will turn red for 0.5S once switch on.
b. The LED indicator light will turn green continually while receiving data from
air.
c. The LED indicator light will turn red continually when transmitting data into air
after receiving from COM.
d. If the module keeps sleep function, LED indicator light is always dark.
7. Supported protocol and Transmit capability
KYL-200U standard transceivers offer transparent protocol to support various
applications and protocols of users. If the user needs to decrease his cost or ease the
workload of terminal CPU, we can add other specific functions based on the
transparent protocol, such as addressing, data acquisition, command interpretation,
etc.
8. Sleep function instruction:
In order to reduce consumption, KYL-200U transceivers support Sleep function. In
sleep mode, the current consumption is less than 20uA.
a. How to use the Sleep function:
The Pin8 ‘SLP’ in JP1 is the signal of sleep control. At high power level,
transceiver stays in working mode. At low power level (<0.5V), transceiver stays
in sleep mode. The SLP signal can convert transceiver from working to sleep
mode in 1ms after falling edge. If the Sleep signal arrives when the transceiver is
transmitting data, the module will move to sleep mode after finishing
transmission. From sleep mode to working, it takes the transceiver 1ms after
rising edge.
To disable the opened sleep function of KYL-200U, the SLP (SLEEP) pin
should be definitely connected with 0 or ground.
