4. COMMUNICATION PROTOCOL
4-1. Communication Setting
The communication protocol is byte oriented. Both sending and receiving bytes are in
hexadecimal format. The communication parameters are as follows
Baud rate: 9,600 ~ 115,200 bps
Data: 8 bits
Stop: 1 bit
Parity: None
Flow control: None
4-2. Communication Format
Host to SL025:
Preamble
Len
Command
Data
Checksum
Preamble: 1 byte equal to 0xBA
Len: 1 byte indicating the number of bytes from Command to Checksum
Command: 1 byte Command code, see Table 3
Data: Variable length depends on the command type
Checksum: 1 byte XOR of all the bytes from Preamble to Data
SL025 to Host:

Len
Command
Status
Data
Checksum
Preamble: 1 byte equal to 0xBD
Len: 1 byte indicating the number of bytes from Command to Checksum
Command: 1 byte Command code, see Table 3
Status: 1 byte Command status, see Table 4
Data: Variable length depends on the command type.
Checksum: 1 byte XOR of all the bytes from Preamble to Data
