Hexin Technology HXJZ-863 200m-500m Micro Power RS-232/RS-485/TTL to RF Wireless Module - Manual (Page 5)

HXJZ-863 Mini Power Wireless Module User’s Manual
Remarks:
To avoid the modules cannot communicate because the interface connecting reverse, please check and
confirm that the voltage of 3 and 4 pin is existing by using multimeter. If there is one pin that has the voltage,
another has not voltage, which means the interface is connected reversely, pls. Change the connection wires
between pin 3 and 4.
2) Power supply
HXJZ-863 uses DC power supply with voltage of +5V.
It can also share power supply with other equipment, however, the high quality power supply with desirable
ripple factor should be selected.
In addition, the reliable grounding must be used if there is other device in the system equipment.
In case of failure to connect with the earth, it can form its own grounding ,but it must be absolutely
separated from the municipal electric supply.
3) Sleeping function
HXJZ-863 had sleeping and no-sleeping version.
The current of HXJZ-863 in the sleeping state is 2Ua. Users must tell which version will be chosen
before place the order in advance.
For sleeping version, users can open and close the sleeping function by themselves.
HXJZ-863 with the sleeping function has two awakening way, one is hardware awakening way, another
is interface awakening way( air awakening will be reserved).
Hardware awakening is achieved by the Pin 5 input to the high level and input low level to awake.
Interface awakening is achieved by users send designate protocol data by HXJZ-863 interface to open
or
awake.
HXJZ-863 with the function of sleeping is default in close state before leaving factory, so users must set by
HXJZ-863 software to set the awakening mode to hardware awakening or interface awakening. Users can also
tell
us to set in advance.
If users use HXJZ-863 with the sleeping function, but hope not to apply the sleeping function, the users
can
set by HXJZ-863 software to set for no-sleeping state or make HXJZ-863 pin 5 to connect the ground in the
mode of hardware awaken.
HXJZ-863 parameters setting
HXJZ-863 can supply three kinds of interface ,they are TTL、 RS232、 RS485, You must tell us which interface
you need before place an order.
HXJZ-863 main parameters: COM baud rate and verify, RF baud rate, Channel and
frequency. You can change these parameters by our RF Module software.
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.
