Methods of Remote Control
Methods of Remote Control
The OmniBER 720 can be remotely controlled in one of four ways:
GPIB Provides a parallel interface that allows the connection of other
devices to the system for example: Frequency Counter; Printer;
Signal Generator. Allows great flexibility in communicating
data and controlling data and provides one of the easiest
methods of constructing automatic systems. If long distance
communication is required, suitable GPIB Extenders must be
connected within the test system at both ends of the
communication link.
RS-232-C Provides a serial interface that can be connected directly to the
RS-232-C port of a terminal or computer. Only the controller
and the OmniBER 720 can be connected within the system. If
long distance communication is required, the OmniBER 720
can be connected directly to the RS-232-C port of a Modem and
controlled via a telephone line.
LAN Provides a parallel interface that allows the connection of other
instruments and controllers to the system for example:
workstations; other OmniBER 720’s; other test sets that have a
LAN interface.
DNA Provides control via a Front Panel displayed on a PC connected
to a LAN. Other test sets that have the Virtual Remote
capability can be connected to the LAN and controlled via the
same PC. See E4540A DNA Remote Software manual.
UID’s OmniBER Universal Instrument Drivers - please refer to the
UID sales flyer provided with your instrument for information
on OmniBER UID’s which are provided on a CD-ROM with
your instrument.

Methods of Remote Control
Connecting the OmniBER 720 via GPIB
The following points should be considered when connecting the OmniBER 720 via
GPIB:
• Operating distances
• Communication with the system controller
Operating Distances
1. The total length of GPIB cable must not exceed 2 meters (6 feet) ×the number of
devices in the system.
2. The total length of GPIB cable, used to interconnect all devices in the system,
must not exceed 20 meters (65 feet).
Operating distances can be increased by using GPIB Extenders, as follows:
Up to 1250 meters use 37204A.
Over 1250 meters use two 37201A and two suitable Modems.
Communication with the System Controller
Each device in the system must have a unique address to allow the controller to
access each one individually. On the OmniBER 720 the address is set on the
OTHER display under REMOTE CONTROL:
To set the GPIB Address press
;
and set the display as shown
opposite. Address 5 has been
selected but any Address in the
range 0 to 30 can be selected.

Methods of Remote Control
Connecting the OmniBER 720 to RS-232-C
Remote control via RS-232-C requires that the OmniBER 720 RS-232-C interface
settings match those of the terminal/computer. These settings are made on the
OTHER display under REMOTE CONTROL.
Using , and the display softkeys
set REMOTE CONTROL PORT
[RS232]. Set CONTROLLER TYPE,
XON/XOFF, SPEED, PARITY and STOP
BITS to match the settings on your
terminal/computer.
Refer to the following pages for a list of instrument RS-232-C port connections,
cable connections between the instrument and a PC, Modem or Terminal, and an
explanation of controller type.
OmniBER 720 RS-232-C Port
The OmniBER 720 acts as DCE (Data Communications Equipment), see Table 1-1
for a list of port connections.

Methods of Remote Control
Connection via a Modem
Full Modem control is not possible and the Modem should be configured to force
DSR, DCD, CTS and DTR true.

Controller Type
Two methods of controlling the OmniBER 720 via RS-232-C are available:
Terminal Simple method of control when commands are issued manually
on a command by command basis.
Computer Typically used when commands are issued via a program.

Methods of Remote Control
Terminal Mode
Terminal mode is provided to allow the OmniBER 720 to be controlled by a "dumb"
terminal and provides the following features:
When connection is established via RS-232-C the OmniBER 720 responds with
a "prompt".
Characters sent to the OmniBER 720 are echoed back to the terminal.
If a mistake is made in the command, the appropriate SCPI Error Message and
the "entered" command is returned to the terminal to provide a local record.
A command history buffer is provided with a capacity of 20 commands. This
allows frequently used commands to be retransmitted without having to retype
the command:
To list the history buffer contents type: !l (lower case L)
To retransmit the last Command sent type : !!
To retransmit a previously sent command, type: !n where n = the commands
listed number. If "n" is negative, the number is relative to the last command
sent.
Computer Mode
Computer mode is provided to allow the OmniBER 720 to be controlled by a
computer allowing programs to be run. Unlike Terminal mode commands are not
echoed back and SCPI Error Messages are not returned unless the appropriate query
command is issued.
