3.12.1 Remote sense
Remote voltage sensing is used to maintain good regulation at the load and reduce the degradation of regulation that would occur due to the voltage drop in the leads between the power supply and the load. By connecting the supply for remote voltage sensing, voltage is sensed at the load rather than at the supply's output terminals. This will allow the supply to automatically compensate for the voltage drop in the load leads and improve regulation.
Local sense
Local sense doesn’t compensate for the voltage drop on the wire, the operation is:
1. Use the shorting clip already installed on the rear panel, or install wires between Drive+ and Sense+, Drive- and Sense-.
2. Connect the positive and negative terminals on the front panel or the Drive + Drive- terminalson the rear panel to the device under test (DUT).

Chapter5 Remote Operation Mode
IT6100B configure with three type of communication interface RS232, USB and GPIB for user adopting any of it flexible.
5.1 RS232 interface
There is a DB9 connector at the rear of the power supply, when connect to computer, you need to connect a cable with COM port on both side; active
connection, you need to set the front panel composite press (Shift)+ configuration settings the same as computer configuration settings. RS-232 interface can be used to program all of the SCPI orders.
RS-232 data format
RS-232 data is a 10-bit word which has a start bit and a stop bit. The start bit and stop bit can not be edited. However, you can select the parity items with (Shift)
+ Parity options are stored in nonvolatile memory.
Baud Rate
The front panel (Shift) + which is stored in the non-volatile memory: 4800/9600/19200/ 38400/57600/115200
key
NOTE
RS232 settings must match the settings in front panel system information. If any change, please press (Shift) +
key on the front panel.
key.
button allow the user to select a baud rate
RS-232 connection cable
Use a RS232 cable with DB-9 interface, RS-232 serial port can connect with the controller (eg PC). Do not use blank Modem cable. Below table shows the plug pins.
If your computer is using a RS-232 interface with DB-25 connector, you need a 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.).
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 8 data bits, have even parity ODD 8 data bits have odd parity NONE 8 data bits, no parity Local Address: (0 ~ 31, the factory default setting is 0)
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.
