To check the COM settings, see the Device
Manager in the PC. For WinXP; Control panel
→ System → Hardware tab.
Run this query command via the terminal after
the instrument has been configured for
RS232/USB remote control (page 5).

INTERFACE OVERVIEW
Background
Realterm is a terminal program that can used to
communicate with a device attached to the
serial port of a PC or via an emulated serial port
via USB.
The following instructions apply to version
1.99.0.27. Even though Realterm is used as an
example to establish a remote connection, any
terminal program can be used that has similar
functionality.
Note
Realterm can be downloaded on Sourceforge.net
free of charge.
For more information please see
http://realterm.sourceforge.net/
Operation
1. Download Realterm and install according to the
instructions on the Realterm website.
2. Connect the PEL-3000 via USB (page 5) or via
RS232 (page 7).
3. If using RS232, make note of the configured
baud rate, stop bits and parity.
4. Go to the Windows device manager and find
the COM port number for the connection.
For example, go to the Start menu > Control
Panel > Device Manager
Double click the Ports icon to reveal the
connected serial port devices and the COM port
for the each connected device.
Using Realterm to Establish a Remote Connection
9
PEL-3000 Programming Manual
If using USB, the baud rate, stop bit and parity
settings can be viewed by right-clicking the
connected device and selecting the Properties
option.
5. Start Realterm on the PC as an administrator.
Click:
Start menu>All Programs>RealTerm>realterm
Tip: to run as an administrator, you can right
click the Realterm icon in the Windows Start
menu and select the Run as Administrator
option.

Command
Structure
SCPI (Standard Commands for Programmable
Instruments) commands follow a tree-like
structure, organized into nodes. Each level of
the command tree is a node. Each keyword in a
SCPI command represents each node in the
command tree. Each keyword (node) of a SCPI
command is separated by a colon (:).
For example, the diagram below shows an SCPI
sub-structure and a command example.
:RESPonse:CRANGe :VRANGe
[:MODE]:CRANGe
:MODE
COMMNAND OVERVIEW
The Command overview chapter lists all PEL-3000 commands in
functional order as well as alphabetical order. The command syntax
section shows you the basic syntax rules you have to apply when
using commands.
Command Syntax
16
COMMNAND OVERVIEW
Command types
There are a number of different instrument
commands and queries. A command sends
instructions or data to the unit and a query
receives data or status information from the
unit.
Command types
Simple
A single command
with/without a parameter
Example
:CONFigure:RESPonse MAX
Query
A query is a simple or
compound command
followed by a question mark
(?). A parameter (data) is
returned.
Example
:CONFigure:RESPonse?
Compound
Two or more commands on
the same command line.
Compound commands are
separated with either a semicolon (;) or a semi-colon and a
colon (;:).
A semi-colon is used to join
two related commands, with
the caveat that the last
command must begin at the
last node of the first
command.
A semi-colon and colon are
used to combine two
commands from different
17
PEL-3000 Programming Manual
nodes.
Example
CONFigure:VON
MAX;:CONFigure:VDELay
MIN
Command Forms
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.
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
form
:CURRent:LEVel?
:CURRENT:LEVEL?
:current:level?
Short
form
:CURR:LEV?
:curr:lev?
Square Brackets
Commands that contain square 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
For example for the query:
“[:CONFigure]:GNG [:PASS]?”
Both “:CONFigure:GNG:PASS?” and “:GNG?”
are both valid forms.

(Optional
parameter)
For commands, this will set the
setting to the lowest value. This
parameter can be used in place of
any numerical parameter where
indicated.
For queries, it will return the
lowest possible value allowed for
the particular setting.
[MAX]
(Optional
parameter)
For commands, this will set the
setting to the highest value. This
parameter can be used in place of
any numerical parameter where
indicated.
For queries, it will return the
highest possible value allowed
for the particular setting.
Unit Suffixes
(Optional
parameters)
Unit suffixes can be optionally
used with most NRf type input
parameters.
