TROUBLESHOOTING THE SNAP PAC R-SERIES CONTROLLER
SNAP PAC R-Series Controller User’s Guide

CAUTION:
Note the following recommended settings:
If you set these fields too low, you may not be able to communicate with the device at all, even
through PAC Manager, to fix the settings. Then you would have to reset the controller to
factory defaults (see
page 49
).
4.
Change these four fields as necessary:
Minimum RTO
sets an absolute minimum value for the RTO. The device’s calculated
RTO will never go below this value.
Initial RTO
sets the RTO for the first communication try. Be careful: since all future tries
are based on this value, if you set it too low for network conditions, a connection will
never be made.
TCP Retransmits
sets the number of times the device retries communication. Larger,
busier networks need a higher number of retransmits than smaller networks with less
traffic.
TCP idle session timeout
sets how long (in milliseconds) the device allows a session
to remain open without any activity. After this time, the device checks the session to
TCP Minimum Retransmission Timeout (msec): 250
TCP Initial Retransmission Timeout (msec):
3000
TCP Retransmission Attempts:
5
TCP Idle Session Timeout (msec):
240,000
