RS232 Interface
RS232 is one of the most widely used interface standards. At least one RS232
port is built into every IBM compatible computer. The interface connects two
devices in a full duplex fashion so that both devices can talk simultaneously.
The connection requires that the RS232 receive line of one device is connected
to the transmit line of the second device and visa versa. In addition to this
connection, some devices require the connection of “handshaking” lines to signal
the beginning and the interface conversation.
To set up an RS232 instrument, an RS232 cable must be connected between the
instrument and the computer. The port on the computer must be specified along
with the settings of the remote instrument. The computer RS232 port must be
specified and the settings of the port must be adjusted to the settings of the
remote instrument. FPG Tools provides setup features to facilitate this step.
Refer to the instrument’s manual to determine how to retrieve the RS232 settings.
If the remote interface selection is RS232, the
<RS232 Settings>
screen must
be used to specify the specific setting information. The
<RS232 Settings>
screen is called up in FPG Tools
by clicking any of the RS232 settings displayed.
Select the correct settings for the device from the drop down lists and click
<OK>
when ready. All settings, with the exception of the
<COM Port>
, are defined by
the device that will use the interface. Refer to the instruction manual of that
device to determine these settings and make any necessary selections for the
interface to function in RS232. The
<COM Port>
selection should represent the
physical connection of the device and an RS232 port on the host computer or the
currently configured reference device.
