Programming the 9730
Personal Computer to Pulse Generator Communication
The 9730 comes standard with a RS232 serial and USB interface. An Ethernet
interface is available as an option. All menu settings can be set and retrieved over the
computer interface using a simple command language. The command set is structured
to be consistent with the Standard Commands for Programmable Instruments (SCPI).
Although due to the special features optional in the 9730, some of the commands are
not included in the specification. The syntax is the same for all interfaces.
RS232 Interface Overview
The serial port is located on the back of the 9730 and uses a 9-pin D-type connector
with the following pin-out (as viewed from the back of the unit):
 No Connection

– Transmit (to computer)
 Rx – Receive (from computer)
 DTR – Connected to pin 6
 Ground
 DSR
– connected to pin 4
 RTS – Connected to pin 8
 CTS – Connected to pin 7
 No Connection
