3.12 Terminals at rear panel
The terminals at rear panel of IT6100B include: remote sense, DVM and milliohm
meter, I/O port.
The terminals at rear panel of IT6121B/IT6122B/IT6123B/IT6132B/IT6133B.
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).

stop bit can not be edited. However, you can select the parity items with (Shift)
+
Parity options are stored in nonvolatile memory.

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)
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.
First, Connect the GPIB interface on the power supply and the GPIB card on
computer via IEEE488 bus, must be full access and tighten the screws. Then set
the address, the address range of the power : 0 to 30, can set by the function key
on the front panel, press the (Shift)+
function, find the GPIB address setting bybutton, type the address,
key to confirm. GPIB address is stored in nonvolatile memory line
5.4 Communication protocol
IT6100B programming should adopt SCPI communication protocol, please contact
ITECH to get the protocol you need.
ITECH provides you with optional red and black test lines, which individual sales
and you can select for test. For specifications of ITECH test lines and maximum
current values, refer to the table below.
For maximum current of AWG copper wire, refer to table blow.
Note: AWG ( American Wire Gage), it means X wire ( marked on the wire).
The table above lists current capacity of single wire at working temperature
of 30°C. For reference only.
