This section provides information on the proper use and configuration of the bus
remote interface. The USB/RS-232 remote interface is standard on the SC6540
but the GPIB (IEEE-488) and interface option can be substituted for the USB/RS-
232 interface. The USB/RS-232 interface uses the same command set as the
GPIB interface for setting test parameters; however, many functions of the GPIB
488.2 interface are not available through USB/RS-232. The IEEE-488 interface
included with the SC6540 conforms to the requirements of the IEEE-488.2
standard.
The USB/RS-232 interface card requires the user to download a driver in order
for the instrument to recognize the USB interface. The driver can be found on the
Associated Research, Inc. website:
http://www.asresearch.com/products/software/USB-driver.aspx
Click on “USB/RS-232 Driver” to download the driver. This link contains an
automatic extract and install program. Follow the instructions of the installation
program to initialize the driver install. NOTE: The USB port acts as a USB to RS-
232 converter. As a result, the PC will recognize the USB port as a virtual COM
port.
5.1. USB/RS-232 Interface
This interface provides all of the control commands and parameter setting
commands of the GPIB interface with the exception of some of the 488.2
Common Commands and SRQ capability. All commands can be found in section
5.5. USB/RS-232/GPIB Command List. The identification command *IDN and
the Status Reporting commands are also available through USB/RS-232.
5.1.1. RS-232 Connector
The RS-232 cabling should be configured as follows for a 9-pin serial port
interface:
