RS-232
If your computer is using a RS-232 interface with DB-25 connector, you need
an adapter cable with a DB-25 connector at one end and the other side is a
DB-9(not blank modem cable).
PC and power supply must have the same configuration in the following
items: baudrate, parity bit, data bit and flow control. Please note that power
supply has been configured with a start bit and stop bit(the two values are
fixed).
Ensure you have used the correct communication cable. Please pay atten-
tion that some cable may not have a correct internal wiring even it is with a
appropriate DB9 interface.
The RS232 communication cable should have been connected to a correct
serial port of the PC.
EVEN 8 data bits have even parity
ODD 8 data bits have odd parity
