Introduce:
Wireless transceiver module HR-1025 can be used in any standard or nonstandard
user protocol
The module has highly be avoided disturbance ability, long transmission range, the
distance can extend to 4500m (1200bps) in open field.
Low power consumption, transmitting current 450-550mA, Receiving current
32-38mA, sleeping current 3uA
The frequency is 433Mhz or 868Mhz
User can order the channel, we can supply 8 channels normally, as the user needs
we can design 16 or 32 channels too.
The module has TTL/RS232/RS485 interface, 7E1, 8N1, 7E2, 8E1, 8O1, 9N1
verify
We can supply the 1200bps/2400bps/4800bps/9600bps/19200bps baud rate, user
can choose one of the baud rate as you want
The user can also choose any antenna to match the modules

Ⅲ、Interface definition:
HR-1025 (V1.1) module can supply a 9-pin connecter (CON1), and its definitions
as well as connection method for terminals are following show:

Ⅳ、Setting of the channel, interface, data rate and data format:
4.1. Before using HR-1025, you have to make simple configuration of your
system parameter such as interface and data format.
There is one group of 5-bit short-circuit wire(J1) on the bottom left corner of
HR-1025, defined as A, B, C, D, E respectively, assuming the open circuit wire (with
short circuit) is mode 0

Above figure is do not input the jumper, input jumper means make the two points join
together as the following show:
4.2 Channel configuration:
ABC jumper wires of J1 provide 8 options and you can choose 0-7 channels (ABC
jumper wire mode is the same), you can transmit data between each module, but keep
in mind at the same time only one modules is in TX mode.

4.3. Selection of interface mode:
HR-1025 (V1.1) provides there types of interface mode, COM1 (Pin3 and Pin4 of
CON1) is fixed as UART
Serial port of TTL level: COM2 (Pin6 and Pin7 of CON1) can choose interface
mode (RS-232, RS485) through D of J1
(1). TTLinterface connection application circuit

Note: Please do not connect any wire on Pin6 and Pin7 and also if the other wire
you do not use, please cut them down, or it will has interface.
If you use the TTL only please make sure the D jumper of JP2 without jumper wire
(D=0)
(2). RS-232 interface connection application circuit
Note: Do not connect other wires or it will has interface.

Note: If the module and the equipment use different power supply, please make
sure the two use the same GND (join the two`s GND together).
(3). RS-485 interface connection application circuit
Note: Do not connect other wires or it will has interface

4.4: Interface rate setting
The rate of HR-1025 is determined by hardware to make sure the module rate is
suit to your system, we must tell your system`s rate.
4.5: HR-1025 can support no parity and even parity mode of the serial
communication
UART it can choose parity mode through E of J1
E=0 (without short circuit) parity 8E1 (even parity) 8O1/9N1/7E2
E=1 (with short circuit) parity 8N1 (no parity) 7E1
Note: channel setting COM2`s interface mode and parity mode is fixed after the
power is on if you want to change the setting, you must reset the module or power on
again.
Ⅴ、Indicator led function:
1. When power on the module, green led will flash one time, it means the module
is now is now output an edition information, from the edition users can know
HR-1025 (V111) C=00 (433), RS232/RS485, 8N1/9N1
Note: HR-1025 means the module brand, (V111) means the module`s edition
number.
“00” means channel number, RS485/RS232 is the interface choose 8N1/9N1 is the
verify mode.
2. When the data need to transmit to the air, Red led will flash one time (when
use RS232 or RS485 interface the light will not flash)
3. When the module receive the data from air, the Green led will flash again
Ⅵ、Time diagram:
HR-1025 has sleeping mode, it is controlled by SLP pin, usually the SLP is in the
high level mode (SLP=1), if you need the modules in the working mode, you need
make the RST pin become high level, User can reset or repower on the module, the
timing map as following show:

Transmit timing delay
When the RXD of the HR-1025 (named A) receive data, then the modules send the
data to modules B(HR-1023), then the TXD output the data, between those transmit it
has a timing delay (Td), different baud rate has different delay time, example: when
you choose 1200bps, you need add 122ms delay in your program.
