No. Name and Description
14 [NAK No Memory]
Number of NAKs sent by the serial converter because it
did not have sufficient memory to buffer the incoming
messages. The serial converter runs out of memory if a
command has not completed and there is no place to
save the new commands.
15 [Duplicate Msgs]
Number of duplicate messages sent by the serial
converter. This value contains the total number of
consecutive messages received by this device with the
same TNS (Transaction Sequence) number.
16 [Interface Select]
Auto Converter will automatically run DPI if
connected to a DPI product or SCANport if
connected to a SCANport product.
SCANport Converter will perform SCANport services
only.
Set this parameter to "Auto" (default) unless you are using
DriveExplorer v1.xx or DriveTools32 v2.xx software and
you are connected to a DPI product. Use "SCANport" for
these software versions.
17 [DPI Data Rate]
Data rate used by the DPI host product. This data rate is
set in the drive, and the adapter autobauds to it.
18 [DF1 Addr Actual]
DF1 address actually used by the serial converter.
19 [DF1 Rate Actual]
Serial port rate actually used for the DF1 serial port on the
serial converter.
20 [Ref/Fdbk Size]
Size of the Reference/Feedback. The host product
determines the size of the Reference/Feedback. The
serial converter automatically uses the correct size.
(2)
21 [Datalink Size]
Size of each Datalink word. The host product determines
the size of Datalinks.
(1)
This value is normally a low value. If it is continually incrementing and you are having
communications problems, use a lower baud rate or replace the 1203-SFC serial cable.
(2)
The parameter appears only when the serial converter is connected to a product implementing
DPI.
