RS232 Hi Power Data Sheet P.6
Point-to-Point Transmission: multicast
This mode can be used in multi-point transmission. You can specify receive side
ID when you send data. It can receive data when GID and UID of your equipment
can meet using conditions and under effective signal cover range. If you want to
specify transmission path (maximum is transfer stations), please add Address
and receive side ID before every information, but the data which you send every
time must be less than 64 bytes (it must include Address and ID of receive side).
If you set preset transfer station, you can’t use point-to-point transmission; you
need to cancel transfer station so that you can use point-to-point transmission.

Path order
Preset set process of Point-to-Point Transmission mode
When you use point-to-point transmission mode, please set corresponding
parameters so that it can start to work. Please set according to following steps.
Set RF transmission rateSet equipment UIDSet power consumptionSet RS232
interface rate Set group IDFinish setting
1. Set RF transmission rate: suggest you collocate with interface rate to set when
you start to set. Usually, RF transmission rate must be bigger than interface rate
to avoid error data.
2. Set equipment ID: UID is for identity between equipments. User can specify
point-to-point path through point-to-point transmission.
3. Set power consumption: you can adjust power consumption according to different
application.
4. Set RS232 interface transmission rate: you can collocate with equipment rate.
5. Set group ID: GID is for working group identify. When GID are different,
equipments can ‘t send data or receive data each other.

Example: when GID=1234 and transmitted side which UID=0A send data to
receive side which UID=2A, GID=0000. But equipment which UID=2A can’t
receive any data, only GID=1234 can receive data from receive side which
UID=2A.
Detect interface rate: please switch interface rate and input 72bytes of 0X8D
when you can’t make sure the interface rate. Equipment side will return same
0x8D, total are 72bytes when interface rate is correct.

cancel transfer station. When receiver side returns same 0X8F, total are 72bytes,
it is meaning you cancel preset transfer station. You need to collocate with
point-to-point transmission format after you cancel transfer station so that you
just can start to normal working.

Preset transfer station: this function needs to preset constant path of data
transmission mode. After finish preset, every data doesn’t need to add any
command and path, but the data which you send every time must be less than 64
bytes. Equipment will automatically transfer and send data according to preset
path. Maximum transfer stations you can set are 10. Setting way is to add UID
number on finial receiver side behind the command. If you need to go through
transfer station, you need to insert UID number of path in the middle.
