The Ethernet interface used in the 9730 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 
your computer’s COM port using the Digi Connectware’s “Realport Drivers”. 

Ethernet Interface Overview 

 
Whatever method of Ethernet communication is ultimately desired, the utilities 
supplied by Digi Connectware (included on the disc shipped with the Ethernet-
optioned 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 your computer.  Please refer to the Digi Connectware 
documentation supplied on the disc, or call Quantum Composers technical 
support. 

 

Programming Command Types and Format 

The 9730 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. 
 

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 communication 
port until it reads the line termination sequence. 

Line Termination 

 
The command string is parsed and executed after reading these characters.  
These characters are the “carriage return” and “linefeed”.  They are ascii 
character set values 13 & 10 respectively (hex 0x0D and 0x0A).  All command 
strings need to have these characters appended.
