On the backup interface NUI/NUA selection
If both an NUI and an NUA are included in the call string, this parameter allows the unit to
filter one of these out of the X.25 call request.
Enable X.25 Restart Packets
It is normally possible to make X.25 CALLs immediately following the initial SABM-UA
exchange. In some cases however, the X.25 network may require an X.25 Restart before it
will accept X.25 CALLs. The correct mode to select depends upon the particular X.25 service
to which you subscribe. The default value is “On”. This means that the unit WILL issue X.25
Restart packets. To prevent the unit from issuing Restart packets set this parameter to
“Off”.
Restart delay
When the Restarts parameter is “On” the Restart Delay value determines the length of time
in milliseconds that the unit will wait before issuing a Restart packet. The default value is
2000 giving a delay of 2 seconds.
IP Settings
Remote IP address
This field indicates the destination host that will answer the XOT, TCP, SSL, UDP call.
Remote IP Address when using the backup interface
This field indicates the destination host that will answer the XOT, TCP, SSL, UDP call if a
connection via the primary interface has failed and the PAD is configured to backup to a
secondary interface that is using an IP based protocol.
IP Stream port
This is the TCP or UDP port number to use for IP (but not XoT) connections.
IP length header
When set to “On”, and in IP Stream mode, the length of a data sequence is inserted before
the data. For the receive direction it is assumed the length of the data is in the data stream.
When set to “8583 Ascii 4 byte”, the IP length header will conform to the ISO 8583 format.
PAD Settings
PAD prompt
This parameter allows you to redefine the standard “PAD>” prompt. To change the prompt
enter a new string of up to 15 characters into the text box.
PAD mode
The PAD Mode parameter can be set to “Normal” or “Prompt Always On”. In Prompt Always
On mode, the ASY port attached to the PAD behaves as if it were permanently connected at
layer 2, i.e. it always displays a “PAD>” prompt. AT commands may still be entered but the
normal result codes are suppressed. To disable this mode set the parameter to “Normal”.
Use PAD Profile
The PAD profile # allows you to select the PAD profile to use for this PAD instance. There
are four pre-defined profiles numbered “50”, “51”, “90” and “91”. In addition to the pre-
defined profiles you can also create up to four user-defined profiles numbered “1”, “2”, “3”
and “4”. To assign a particular profile to the PAD select the appropriate number from the
list.
Strip Trailing Spaces
When this parameter is turned on any spaces received at the end of a sequence of data
from the network will be removed before being relayed to the PAD port.
