User’s Manual
When the speed rate in the air is quicker than interface’s, allowing to transmit unlimited length data at one
time, when the speed rate is slower or equal the interface’s, allowing the transmission of 255 Bytes long data
frames at one time for more flexible programming by users.
12. Intelligent data control 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-875
will automatically
complete the other operations, such as transmission/receiving conversion in the air, control, etc.
13. 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.
14. Watchdog monitor
Watchdog monitors the inner function, so that change the traditional product structure and
improve the product reliability.
