RS-232 data format
RS-232 data is a 10-bit words which has a start bit and a stop bit. The start bit
and stop bit cannot be edited. However, you can select the parity items with
+
I-setI-set
key on the front panel. Parity options are stored in nonvolatile
memory.
Baud Rate
The front panel +

button allows the user to select a baud rate
which is stored in the non-volatile memory: 4800 /9600/ 19200 /38400/
57600 /115200.
RS-232 connection cable
Use a RS232 cable with DB-9 interface, RS-232 serial port can connect
with the controller (e.g. PC). Do not use blank Modem cable.
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)

RS-232 Troubleshooting:
If there is RS-232 connection problem, check the following:
 Computer and power supply must configure the same baud rate,
parity, data bits and flow control options. Note that the power
configuration as a start bit and a stop bit (these values are fixed).
 As described before in RS-232 connector, you must use the correct
interface cable or adapter. Note that even if the cable has the right
plug, the internal wiring may be wrong.
 Interface cable must be connected to the correct serial port on the
computer (COM1, COM2, etc.).
