Bit3 ~Bit5: Invalid character, fixed as 000.
Bit6~Bit7: 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 ofA.
Mode 3 (ID data mode 2: setup value 10)
In this mode, it is allowed to transmit data to specified GID and SID
device, in order to achieve one-to-multiple-transmission, but the single
data including specified GID and SID should not exceed 127Bytes.
Way of transmission:
The data will be transmitted through the order of 13th byte to 32nd byte.
Example:
Device A shows GID=AAA, SID=55, device B shows GID=BBBB, SID=88,
device C shows GID=CCCC, SID=99.
Device A is going to transmit a 5-byte data 0x1234567890 to B so A sends
a 10-byte data 0x04FFBBBB881234567890, and then B receives a 5-byte
data 0x1234567890.
Device A is going to transmit a 5-byte data 0x1234567890 to device C
through device B, then device A sends a 14-byte data
0x08FFBBBB88FFCCCC991234567890, while device B will not receive
anything, and then device C receives a 5-byte data 0x1234567890.
Mode 4 (saved ID data mode: setup value 11)
During this mode it is allowed to pre-save the path of specified GID and
SID. When sending signals the system will automatically follow the
pre-saved value to transmit, it is up to 14 times of transmission and single

data of pre-saved GID and SID should no greater than 127 Bytes.
12th Byte: Invalid character, fixed as 0X00
13th to 32nd Byte: Pre-saved path, it only activates in mode 4 (saved ID
data mode).
13th Byte: It stands for the valid data among 14~32 bytes.
14th ~32nd Bytes format of path:
Example 1: 04 FF 12 34 55 11 22 33 44～00
The 13th Byte shows the valid data is 4-Byte FF 12 34 55
FF 12 34 55, it stands for GID=1234, SID=55. This device will receive
data from UR and automatically sends to device with GID=1234 and
SID=55.
Example 2: 05 FF 12 34 55 11 22 33 44～00
The 13th Byte shows the valid data is 5-Byte FF 12 34 55 11
FF 12 34 55 11, it stands for GID=1234, SID=55 and 11. This device
will receive data from UR and automatically sends to
The device with GID=1234 and SID=11.
Example 3: 06 FF 12 34 55 11 22 33 44～00
The 13th Byte shows the valid data is 6-Byte FF 12 34 55 11 22
FF 12 34 55 11 22, it stands for GID=1234, SID=55, 11 and 22. This
device will receive data from UR and automatically sends to
The device with GID=1234 and SID=55 and transferring to the device
with GID=1234, SID=22.
Example 4: 08 FF 12 34 55 FF 45 67 88 44～00
The 13th Byte shows the valid data is 8-Byte FF 12 34 55 FF 45 67 88, it
stands for GID=1234, SID=55, GID=4567 and SID=88. This device will
receive data from UR and automatically sends to device with GID=1234
and SID=55 and transferring to the device with GID=4567 and SID=88.
