Programming the 9500+
Personal Computer to Pulse Generator Communication The
9500+ comes standard with an RS232 serial interface, USB and GPIB
interface. An Ethernet interface is available as an option that would replace the
USB interface. 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.
Although due to the high number of special features found in the 9500+, 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 9500+ 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
Data Bits 8
Parity None
Stop Bits 1
GPIB Interface Overview
Also known as IEEE-488 computer interface is standard on the 9500+. Before
using this interface, the address must be set using the GPIB address menu item.
The command set is the same for the RS-232, GPIB and USB (or Ethernet).
Different interfaces may be used at the same time. Responses will be made to
the most recently used interface. Beginning with Firmware Version 1.18, the
“Echo” functionality is not available on the GPIB, USB or Ethernet port.
