 Control by PC (Computer Link)
When using the RS-485 serial communication interface, you must first specify a communication
address to every Power Regenerative Unit in Pr.04-00. The computer then controls the units based
on their individual addresses.
 Modbus ASCII (American Standard Code for Information Interchange): Each byte of data is the
combination of two ASCII characters. For example, one byte of data: 64 Hex, shown as ‘64’ in ASCII,
consists of ‘6’ (36Hex) and ‘4’ (34Hex).
1. Code Description
The communication protocol is in hexadecimal, ASCII: “0” … “9”, “A” … “F”, every hexadecimal
value represents an ASCII code. The following table shows some examples.
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
