RS-232 Troubleshooting:
If you meet some problems when communicating with PC by RS232
interface,please check the following items:
⚫
Please check the parameters setting
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).
⚫
Check the cable
Ensure you have used the correct communication cable.Please pay
attention 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.
Communication Setup
Please ensure the PC and the load have the same configuration in the following
items.
baudrate
：
9600(4800
、
9600
、
19200
、
38400
、
57600
、
115200)
。
You could enter
the system menu to set the baudrate.
Data bit
：
8
Stop bit
：
1
Parity bit
：
(none,even,odd)
EVEN
8 data bits have even parity
ODD
8 data bits have odd parity
NONE
8 data bits have no parity
Native machine address: ( 0 ~31, factory default is 0)
Parity=None
Start Bit
8 Data Bits
Stop Bit
5.2 USB Interface
Connect the load and the computer using a cable with two USB interfaces (each
end). All functions of the load can be programmed via USB.
The functions of load USB488 interface are as follows:
⚫
The interface is 488.2 USB488 Interface.
⚫
The interface receives requests of REN_CONTROL, GO_TO_LOCAL and
LOCAL_LOCKOUT.
