FEATURE
DESCRIPTION
Data Acquisition
Type
(required drop
down list
selection)
Defines how read and/or set values will be communicated to and/or from the device. Each
choice requires unique settings to be entered. The available
<Data Acquisition Types>
are:
Manual
Output values are entered manually by the operator and/or set values are executed
manually by the operator. No further selections on the
[Communications]
tab are
necessary.
RS232
Read and/or set values will be communicated remotely using an RS232 interface.
Settings specific to the RS232 interface must be complete on the tab. Remote commands to
read and/or set with the device are setup on the
[Output]
and/or
[Set]
tabs.
IEEE-488
Read and/or set values will be communicated remotely using an IEEE-488
interface. Remote commands to read and/or control with the device are setup on the
[Output]
and/or
[Set]
tabs. Remote commands to read and/or set with the device are setup
on the
[Output]
and/or
[Set]
tabs. The active IEEE-488 interface card manufacturer is
selected in
[Setup][Configuration][Interface]
.
TCP/IP
Read and/or set values will be communicated remotely using a TCP/IP interface.
Remote commands to read and/or set with the device are setup on the
[Output]
Tab.
Other Device
A separate support device such as a DMM will be used to obtain the output
of the device. No further selections on the
[Communications]
tab are necessary.
Handshaking
(conditional listbox
selection)
This feature is available for RS232 interfaces only. Select the devices handshaking protocol
to use with the interface. Handshaking refers to the internal communications protocol by
which data is transferred from the hardware port to the receive buffer. The default selection
is
<None>
. This selection is valid for the majority of remote devices.
None
There is no RS232 handshaking required.
RTS/CTS
Request to Send/Clear To Send handshaking.
XON/XOFF
XON/XOFF
Handshaking
RTSXON/XOFF
Both Request to Send/Clear To Send and XON/XOFF Handshaking
RTS ON/OFF
The PC RTS output is set to HIGH while sending data and set to low when
the data transmission is complete.
RS232 Port
(button Option)
The RS232 port that the PC will use to communicate with the remote device. Change the
selection by pressing the
[Ports]
button. Do not confuse this port selection with the ports
available on a remote device. For example a PPC3 has a COM1 and a COM2 port. This
port selection does not refer to either of these ports. It refers only to the port on the HOST
PC that will be used to communicate with the PPC3. This option is available only when the
<Data Acquisition Type>
is RS232.
RS232 Settings
(button Option)
The RS232 settings of the remote device. The value is listed as: Baud Rate, Parity, Data
Bits and Stop Bits. The field must be set to the settings defined by the remote device. Refer
to the device manual for information on how to obtain the proper RS232 settings. When
incorrect settings are used, proper communication is not possible. Change the selection by
pressing the
[Ports]
button. This option is available only when the
<Data Acquisition
Type>
is RS232.
Binary
(conditional
checkbox
selection)
This feature is available for RS232 interfaces only. Check this box when the RS232
instrument requires binary communications instead of ASCII based communications.
Instruments that use non printable commands sets that include “check sums”, typically
require this option to be checked.
Command
Timeout(s)
(numeric entry;
remote interface
<Data
Acquisition
Type>
only)
The maximum length of time for the device to wait for a response from a remote command.
If a response is not received within this amount of time, a timeout occurs.
