Usb Interface - ITech IT6121B User Manual

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.).
Communication Settings
Before communication, you should first make the following parameters of power
supply and PC matches.
Baud Rate: 9600 (4800, 9600, 19200, 38400, 57600, 115200). You can enter the
system menu from the front panel, and then set the baud rate.
Data bits: 8
Stop Bits: 1
Calibration (none, even, odd)
EVEN
ODD
NONE
Local Address: (0 ~ 31, the factory default setting is 0)
Parity=None

5.2 USB interface

Use a Cable with two USB port to connect the power and the computer. All power
functions can be programmed via USB.
The USB488 interface functions of the power supply described as below:

Interface is 488.2 USB488 interface.

Interface receiver REN_CONTROL, GO_TO_LOCAL, and LOCAL_LOCKOUT
request.

Interface receives MsgID = TRIGGER USBTMC order information, and will
pass TRIGGER order to the functional layer.
Power USB488 device functions described as follows:

Devices can read all of the mandatory SCPI orders.

Device is SR1 enabled.
8 data bits, have even parity
8 data bits have odd parity
8 data bits, no parity
