Computer Control /Computer Link
Before using RS-485 Serial Interface, each drive needs to pre-assign a communication
address specified by Pr.9-00. The computer then controls each brushless DC drive according
to its communication address
A BLD-E1 can be set up to communicate in MODBUS networking using ASCII
mode(American Standard Code for Information Interchange), each 8-bit data is a combination
of 2 ASCII character. For example, a 1-byte data: 64Hex, shown as ‘64’ in ASCII, consists of
‘6’ (36Hex) and ‘4’ (34Hex).

ASCII mode:
Each 8-bit data is the combination of two ASCII character. For example, a 1-byte data:
64 Hex, shown as ‘64’ in ASCII, consists of ‘6’ (36Hex) and ‘4’ (34Hex).
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’
