Keepalive is a function supported by TCP. It sends packets at constant time intervals and
automatically disconnects when there is no corresponding response. This instrument sends
packets at 30-second time intervals. If a response is not received, it sends 4 more packets at one-
second intervals. If a response is still not received, the connection is dropped.
Have dip switch 4 turned OFF.
