Serial interface
Data rate
The speed of the serial connection.
Status
RS-232 connection
Status of the RS-232 connection.
Flowcontrol
Status of flow control.
Port A
Indicates whether serial data is received via DSL connection
A. Errors are also indicated.
Port B
Indicates whether serial data is received via DSL connection
B. Errors are also indicated.
D-SUB
1.
No data reception.
2.
Data is received.
3.
Incorrect configuration. A character-based protocol must
be configured.
4.
Noise at the interface.
5.
An incorrect data rate is probably set. The parameterized
data rate of the device is lower than the actual data rate.
6.
The data is arriving at the serial interface faster than it can
be read.
–
Reduce the data rate of the serial interface.
–
Set longer pause times between the data pack-
ets/telegrams.
7.
A few errors at the interface. This can result in significant
errors, for example. A configuration error is probably pres-
ent, e.g., due to an incorrect data rate or a short circuit on
the data cable.
8.
Many errors at the interface. A configuration error is prob-
ably present, e.g., due to an SHDSL data rate that is too
high or a short circuit on the data cable.
9.
Sporadic parity errors at the serial interface. Check the
wiring of the serial interface. If the serial data cable is rel-
atively long or the quality is not good, decrease the serial
data rate.
10. Over 40% of data packets have parity errors. This can
only be down to a configuration error.Check whether the
following device settings are correct and correspond to
the data to be transmitted:
–
Parity
–
Data bits (7 or 8 bits)
–
Stop bits
–
Data rate
11. The data packets sporadically contain errors relating to
the stop bit. Check the wiring of the serial interface. If the
serial data cable is relatively long or the quality is not
good, decrease the serial data rate.
