Manual

HXJZ-862 Mini Power Wireless Module User’s Manual
8.High speed wireless communications and big data buffe r.
When the airborne speed is bigger than the serial port speed, may transmit infinitely data continuously, and
when the airborne speed is smaller than or was equal to the serial port speed ,may transmit 255 bytes data.
9. Intelligent data cont rol and the user doesn’t need to prepare excessive programs
Even for semi duplex communication, the user doesn’t need to prepare excessive
programs, only receiving/transmitting the data from the interface. HXJZ-862 will automatically
complete the other operations, such as transmission/receiving conversion in the air, control, etc.
10. High reliability, small and light
Single chip radio- frequency integrated circuit and single chip MCU are used for lessened
peripheral circuits, high reliability, and low failure rate.
11. Watchdog monitor
Watchdog monitors the inner function, so that change the traditional product structure and
improve the product reliability.
12. Antenna choose
Users can choose various antennas setting project and antenna according to the user’s different request.
13. Encapsulation Structure, dustproof, waterproof and static proof
Comprised by plastic DOS shell, epoxy encapsulation, dustproof, waterproof and static
proof good anti-jamming.
