Personal Computer to Pulse Generator Communication
The 9530 comes standard with an 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 Program-
mable Instruments. Although due to the high number of special features found in
the 9530, many 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 9530 and uses a 9-pin D-type
connector with the following pinout (as viewed from the back of the unit):
1
No Connection
2
Tx - Transmit (to computer)
3
Rx - Receive (from computer)
4
DTR - Connected to pin 6
5
Ground
6
DSR - connected to pin 4
7
RTS - connected to pin 8
8
CTS - connected to pin 7
9
No Connection
The serial port parameters should be set as follows:
Baud Rate
4800, 9600 19200, 38400, 57600, 115200 (default)
Data Bits
8
Parity
None
Stop Bits
1
*The default baud rate for the RS232 is 115200.
USB Interface Overview
The USB interface is standard on the 9530. Before this type of communication
can be used, the appropriate drivers must be installed on the personal computer
(pc). These drivers are included on the cd that was shipped with your unit.
Please contact Quantum Composers or visit www.quantumcomposers.com for
updated installation files and instructions.
USB communication is achieved by using a mapped (virtual) COM port on the
pc. The driver installation executable will obtain an unused COM port number,
