I Command Format

The following pages detail how to write the commands.
1. The following details how to write the commands
Code [STX] AD [Unit address of this unit] [Transmission Command] : [p] [ETX]
ASCII (02H) – – – – – – – – – – – – – – – – – – – – – – – – – – – (03H)
STX: This shows the data start. STX (ASCII code: 02h) is always prefixed to data. h shows hexadecimal digit.
Transmission command: A command shown in the Command List is designated.
ETX: This shows the data end. ETX (ASCII code: 03h) is always prefixed to data.
The character code is ASCII.
When a command needs a parameter, a colon (:) is used for dividing the command and parameter. The following shows
how to write the commands when two or more commands are specified.
Code [STX] AD [Unit address of this unit] [Transmission Command] : [p1] : [p2] [ETX]
2. Response Command (from the Unit to the PC)
The unit sends back the response command for the transmission command from the PC.
• When the reception was completed successfully
The response command differs between when an ANSWER command (sending back the status or data) is required or
when not required.
• When no ANSWER command is required
The unit sends back the same identifier as that in the transmission command, as shown in the figure.
Transmission command (→ The unit)
[STX] OPL [ETX]
Same identifier
Response command (← The unit)
