5. When the PC asks for the USB driver, select
pel_cdc_2000.inf (downloadable from the GW
website, www.gwinstek.com, PEL-2000A
product corner).
6. On the PC, activate a terminal application such
as MTTTY (Multi-Threaded TTY). To check the
COM port No., see the Device Manager in the
PC. For WindowsXP, select Control panel →
System → Hardware tab.
7. Run this query command via the terminal
application.
*idn?
This command should return the manufacturer,
model number, serial number, and firmware
version in the following format.

ï‚· For RS-232C, set the COM port, baud rate, stop
bit, data bit, and parity accordingly.
To check the COM port No. for RS-232C, see the
Device Manager in the PC. For WinXP, Control
panel → System → Hardware tab.
6. Ensure the terminal application has the
following settings;
7. Baud rate – as per PEL-2000A settings
8. Com Port – as per PC settings (Device

COMMAND OVERVIEW
The Command overview chapter lists all the PEL-
2000A commands and command queries .The
command syntax section shows you the basic rules
you have to apply when using commands.
Command Syntax
ï‚· IEEE488.2, 1992 (fully compatible)
ï‚· SCPI, 1994 (partially compatible)
There are a number of different instrument
commands and queries. A command sends
instructions or data to the electronic load and a
query receives data or status information from the
electronic load.
Command Types
Simple
A single command with/without
a parameter
Example
*OPC
Compound
Two or more commands
separated by a colon (:)
with/without a parameter
Example
UTILITY:SOUND 1
Query
A query is a simple or compound
command followed by a question
mark (?). A parameter (data) is
returned.
Example
UTILITY:SOUND?
PEL-2000A Programming Manual
14
Commands and queries have two different forms,
long and short. The command syntax is written
with the short form of the command in capitals
and the remainder (long form) in lower case.
Short
FETCh:VOLTage?
Short
Long
The commands can be written in capitals or lower-
case, just so long as the short or long forms are
complete. An incomplete command will not be
recognized.
Below are examples of correctly written
commands.
LONG
FETCh:VOLTage?
FETCH:VOTAGE?
fetch:voltage?
SHORT
FETC:VOLT?
fetc:volt?
Commands that contain squares brackets indicate
that the contents are optional. The function of the
command is the same with or without the square
bracketed items, as shown below.
Example:
:LOAD[:STATe]
=
:LOAD:STATe
=
:LOAD
1234
:PROGram:CHAin <NR1>LF

2: single space
3: parameter
