The Ethernet module used is a Digi Connect ME module supplied by Digi
Connectware, Inc. There are several ways to successfully communicate with the
pulse generator over Ethernet. The two most popular methods are raw TCP/IP
(such as Labview or programming with VISA libraries) and by mapping a pc
COM port using the Digi Connectware s Realport Drivers .
Whatever method of Ethernet communication is ultimately desired, the utilities
supplied by Digi Connectware (included on the cd shipped with the Ethernet-
option pulse generator) will be critical to implementing the communications.
Please install these utilities.
Ethernet communication notes:
The Digi Connectware s Digi Device Discovery can be used to
determine what IP address was assigned by the local DHCP server
(if any).
Digi Device Discovery can also be used to open a web interface to the
Ethernet module. Simply double-click on the IP address that is displayed
in the Digi Device Discovery utility.

If a mapped COM port is the desired communication method, the Digi
Connectware s Realport Drivers setup must be used to install the COM
port on the pc. This virtual COM port is then local to the computer it was
installed on. Please refer to the Digi Connectware documentation
supplied on the cd, or call Quantum Composers technical support.
The pulse generator s SCPI parameter
:SYSTem:COMMunicate:SERial:USB n is defaulted to 115200 and
should not be changed for Ethernet communication, whether or not a
mapped COM port is used. The virtual COM port on the pc should be set
to 115200 BAUD.
Echo functionality is not available on the Ethernet port.
Programming Command Types and Format
The 9530 Pulse Generator uses two types of programming commands: IEEE
488.2 Common Commands and Standard Commands for Programmable
Instruments (SCPI). The format is the same for all interfaces. Hyperterminal (in
Windows) or any other generic terminal program may be used to interactively
test the commands using the RS232 interface. The format of each type is
described in the following paragraphs.
Line Termination
The pulse generator uses text-style line terminations. When a command is sent
to the unit, the firmware is programmed to read characters from a communica-
tion port until it reads the line termination sequence.
