RS232 Synchronous Views

ClockSrc The source of the port’s bit rate clock. Split means the transmit clock is

internal and the receive clock is external.

Frame Check Errors The total number of frames with an invalid frame check sequence, input

from the port since system re-initialization and while the port state was Up

or Test.

Aborted Frames The number of frames aborted on the port due to receiving an abort sequence

since system re-initialization and while the port state was Up or Test.

Interrupted Frames The total number of frames that failed to be received or transmitted on the

port due to loss of modem signals since system re-initialization and while the

port state was Up or Test.

Xmt. Underrun Errors The total number of frames that failed to be transmitted on the port, since

system re-initialization and while the port state was Up or Test, because

data was not available to the transmitter in time.

Rcv. Overrun Errors The total number of frames that failed to be received on the port, since

system re-initialization and while the port state was Up or Test, because the

receiver did not accept the data in time.

Synchronous Port Detail View

The Synchronous Port Detail View provides conﬁguration information on a selected entry

from the RS232 Synchronous Port Table, and allows you to modify the conﬁguration values.

This view also provides a color-coded pie chart displaying error breakdown statistical

information. A Clock Source button can be toggled between external, internal and split.

To access: Double-click on an entry in the Synchronous Port Table

Error Breakdown Each statistic is presented as a total amount since the device was initialized

and as a percentage of overall trafﬁc. Three buttons at the bottom of the pie

chart select the way in which the data is represented (Total, Delta, and

Accum). Another button, Clear, works in conjunction with the Accum button.
