Tips on Using the RS-232C Port on the 5071A
Operating and Programming Manual 67
Solution:
One way to find out if there is a DSR problem is to remove the Serial Port cable.
The DSR will be pulled back to a positive voltage and the front panel should re-
activate. As long as there are no other reasons for halting the data (e.g. XOFF)
the 5071A will send data to the RS-232C port even when there is no device
attached.
Using Ctrl-Q in Programs
Because some hang-ups could occur without user intervention during program
operations, it may be useful to add a routine that automatically sends a Ctrl-Q
(XON) to the 5071A. This can be triggered by a timeout that monitors the RS-
232 for incoming data.
Setting the Serial Port Parameters with the Option 300 Front
panel
All 5071A instruments are shipped with a CD-ROM that contains Serial Port
Configuration software. The installation software is located at:
5071A Serial Port Configuration Management Software\Installer\Volume\setup.exe
Double click on the setup icon to install the software. Accept all default folder
names and license agreements. When the installation is complete, an icon will be
added on your desktop called ―5071ASerialConfig‖.
The program "5071ASerialConfig " can be used to determine the current serial
port configuration and to change it to your specific needs. When shipped from
the factory a standard 5071A is set to 2400,N,8,1. It is also possible to change the
configuration using this software.
Upon double clicking the icon, the user interface will appear (below). You will
have the choice of either ―Getting‖ the current serial configuration, ―Setting‖ the
serial port to a desired configuration from the left panel, or ―Saving‖ the current
configuration.
