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.

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

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:
