This screen provides the following:
Field | Description |
---|---|
Port | The port number that corresponds to the port number on the connector cable. |
Mode | The name of the connector. Possibilities include:
The 2-wire configuration must be half duplex: 2 wires for transmitting; 2 wires for receiving. The 4-wire configuration is full duplex if it is point-to-point. If it is point-to-multipoint or multidrop, it might or might not be full duplex depending on how the wiring is done. Definitions:
|
State | Open means the port is in use, and Closed means it is not. Loopback Test or Echo Test can appear if you are testing the port with either the echo or the loopback test. |
Byte Count (Tx/Rx) | The number of bytes transmitted and received since the port
was last reset.
Note: These counters are not available when the port is being tested with either the echo or loopback test. |
RTS/CTS/DTR/DSR/RI/DCD | EIA-232 control signal state. Gray indicates inactive or low signal, and blue indicates active or high signal. |
Flow Control (In/Out) | Indicates whether or not data has been paused due to either hardware flow control or software flow control. Normally these values are blank; red indicates that the data has been paused. |
Error Counts | The number of parity, overrun, and framing errors on this port since it was last reset. |
Reset | Resets the channel. Closes the port if it
is open, disrupts any communication that might be happening, flushes all
data and returns the port to a closed state. Because this option should be
used with caution, a dialog box appears
asking if you want to reset this channel.
CAUTION: Ensure that you have a purpose in resetting the channel. |
Test | Choosing Test takes you to the Test Mode
screen where you can test your transmission with either the Terminal Echo
Test or External Loopback Test.
The echo test determines the validity of your transmissions. The loopback test ensures that the port on the adapter is working properly. Display Results returns you to one of the Test Results screens where you can also end the test. |
