7. Programming the 9530/8530
Personal Computer to Pulse Generator Communication
The 9530/8530 has three standard interfaces which are RS-232, USB, and an Ethernet port. 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 high number of special features found in the 9530/8530,
many of the commands are not included in the specification. The syntax is the same for all interfaces.
The amount of time required to receive, process, and respond to a command at a Baud rate of
115200 is 10 ms. Sending commands faster than 10 ms may cause the unit to not respond properly.
It is advised to wait until a response from the previous command is received before sending the next
command.
WARNING: When communicating with the unit (USB, Serial or Ethernet), avoid sending any
commands that include the “*” character as the unit is booting up. This may result in an undesired
lockup of the instrument.
RS-232 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*
Data Bits 8
Parity None
Stop Bits 1
*Note: The default baud rate for the RS-232 is 115200.
