Example Parameters:
SYNC Byte = 16h (Always.)
Data Count = 00 01h
Source Address = FFh
Destination Address = 20h = 32 decimal
Frame Sequence Number = 7Fh
Opcode = 22 54h
Data = 01h (01h = On)
Checksum = 16h
Transmit Packet:
16 00 01 FF 20 7F 22 54 01 16
Response Packet:
16 00 00 20 FF 7F 00 00 9E

C.2 Remote Port Modes of Operation:
The RLLP Remote Port Packet structure is as follows:
<SYNC> = Message format header character that defines the beginning of a
message. The <SYNC> character value is always 0x16, (1 byte).
<BYTE COUNT> = Number of bytes in the <DATA> field, (2 bytes).
<SOURCE ID> = Identifies the address of the equipment from where the message
<DESTINATION ID> = Identifies the address of the equipment where the message is to be
sent, (1 byte).
<F.S.N.> = Frame sequence number ensures correct packet acknowledgment and
data transfers, (1 byte).
<OPCODE> = This byte identifies the message type associated with the information
data. The equipment processes the data according to the value in this
field. Return error codes and acknowledgment are also included in this
field, (2 bytes).
<…DATA…> = Information data. The number of data bytes in this field is indicated by
the <BYTE COUNT> value.
<CHECKSUM> = The modulo 256 sum of all preceding message bytes excluding the
<SYNC> character, (1 byte).
