22 Configuration Welch Allyn Connex CSK software
Device network settings
1 Device
transmission
timeout
This value represents the maximum time, in seconds, that a device can be connected to Data
Catcher with no communication before the device is disconnected.
2 Definition
cache
This value represents the local or path to the directory where cached definitions are stored.
Note: Cached definitions are only loaded when Data Catcher starts, so any additions or
updates to these files will not be recognized until the application restarts.
3 Connection
types
These checkboxes represent the supported connection types for the device server portion of
Data Catcher.
Note: The “Serial” option available applies to both normal serial connections, and USB
Serial Host Driver connections (for example CP 200 USB).
Note: Changes to this option will not be reflected by Data Catcher until the application is
restarted.
4 Device
heartbeats
This value represents the interval (in seconds) at which heartbeat pings will be sent to
known client devices. This is a standard ICMP ping echo request, sent to a networking client.
When set to “0,” heartbeat pings are disabled.
When a client device connects, it will be marked as a known client and flagged as active.
Once the interval has elapsed, a ping request will be sent to each known client in parallel.
Once a client responds to the request with an echo response, the client will be flagged as
active. If any clients have not responded after one second, a retry request will be sent to
those clients. Up to four retries will be attempted, and any clients that have not responded
after the fourth attempt will be flagged as inactive.
Once the retries have completed, the list of active and inactive device clients will be
forwarded to the host system. Once the list is sent, all inactive clients are removed from the
device list.
