 Control by PC or PLC (Computer Link):
Selects the desired mode along with the RS-485 serial port communication protocol in Pr.09-00.
 Modbus ASCII (American Standard Code for Information Interchange): Each data byte is the combination
of two ASCII characters; for example, a 1-byte data: 64 Hex, is shown as ‘64’ in ASCII, and consists of ‘6’
(36 Hex) and ‘4’ (34 Hex).
1. Code Description
The communication protocol is in hexadecimal, ASCII: “0”, “9”, “A”, “F”, every 16 hexadecimal represents
an ASCII code. For example:
Character ‘0’ ‘1’ ‘2’ ‘3’ ‘4’ ‘5’ ‘6’ ‘7’
ASCII code 30H 31H 32H 33H 34H 35H 36H 37H
Character ‘8’ ‘9’ ‘A’ ‘B’ ‘C’ ‘D’ ‘E’ ‘F’
ASCII code 38H 39H 41H 42H 43H 44H 45H 46H
