7. Host
response XSLT The Host Response XSLT field is used to specify the location of an .xsl file that will be used to
verify responses from an external information host. Whenever XML data, or translated data, is
sent to an information host, the data message is saved as part of the message context. If a Host
Response XSLT file is specified, it is used to translate that original outbound message into an
expected response. This expected response is then compared against the actual response from
an information host.
If no Host Response XSLT is specified, then any response from an information host, regardless of
content, will result in an ACK back to the device.
8. Device
response XSLT If an appropriate, matching host response is received from an external information host, and a
Device Response XSLT is present, then Data Catcher generates a specific response for the
device using this XSLT. This response can include elements saved from the Host Response
comparison (using set-variable and get-variable), it can use custom generated binary data (using
binary-stream), and it can conditionally decide whether an ACK, NACK, or custom message id
should be sent to the original device. This allows the XSLT developer a large amount of flexibility
in controlling the response to the device, above and beyond the generic ACK/NACK responses.
9. Automatic
host resolution In certain system configurations, the IP address of the external host is either not known at
configuration time, or not static. In these cases, the IP address of the host cannot be determined
ahead of time, and must be resolved at the time that connections to the host are attempted. This
feature uses an integrated DCP client to find hosts automatically when devices send messages
to Data Catcher.
When this option is enabled, the “Host IP Address” and “Host Port” fields are disabled, as this
setting overrides those options. Also, the “Host Type” option becomes enabled, and lets you
choose which hosts they would like to find automatically when messages are routed through the
system.
10. Host type When the “Automatic Host Resolution” option is enabled, this option becomes available. It lets
you choose which external host types to look for when finding automatic hosts.
