 Device working in 4 modes as stating below: 

 

Mode 1 (Long-figure data mode: setup value 00) 

In  this  mode,  all  devices  with  same  GID  value  can  receive  data.  It  can 

employ in the situation where data capacity greater than 127Bytes.   

 

Mode 2 (ID data mode 1: setup value 01) 

In this mode, all devices with the same GID value could transmit signal 

to specified SID to achieve one-to-multiple-transmission, but the single 

data should not exceed 127Bytes. 

Example:   

SID value is 55 from device A, SID value is 88 from device B and both of 

them have the same GID. During mode 2, device A is going to transmit a 

5-byte  data  0x1234567890  to  B  so  A  sends  a  6-byte  data 

0x881234567890, and then B receives a 6-byte data 0x551234567890, 

where the first byte stands for SID of A.
