Data to be specified
■Extension specification
Specify the access target network No. in hexadecimal.
• ASCII code: Specify J (4AH) at the head of data. Convert the numerical value to 3-digit ASCII code (hexadecimal), and
send it from the upper digits.
• Binary code: Send 2-byte numerical values from the lower byte (L: bits 0 to 7).
