When you turn on
the CK3 after it was
suspended for 10 to
15 minutes or
longer, the CK3 can
no longer send or
receive messages over
the network.
The host may have deactivated or lost the current
terminal emulation session. In a TCP/IP direct
connect network, turn off the “Keep Alive” message
from host to maintain the TCP session while the
computer is suspended.
The CK3 is
connected to the
network, and you
move to a new site to
collect data. Now,
your CK3 is not
connected to the
network.
Move closer to an access point or to a different
location to reestablish communications until you
reconnect with the network. Any data collected while
out of range is transmitted over the network.
The CK3 appears to
be connected to the
network, but you
cannot establish a
terminal emulation
session with the host
computer.

between the access point and the host computer.
Check with network administrator to make sure the
host is running and allowing users to login to the
system.
