Interference caused an non-existing unit
to appear.
There is a unit that is not compatible with
the maintenance tools.
The port required for communication is
being protected by the Firewall checking
function of Windows or anti-virus
software.
When a maintenance tool is not ended
normally, G-50 will be in a data resending
state, and LAN communication will
increase.
The version of G-50 is old.
Cause
A unit other than an outdoor unit (OC) has
been selected.
An operating SC other than remote
control has been clicked.
Cause
Because of the increased re-transmission
process work due to abundant
communication noise, data may not be
monitored fully within the rated cycle.
There is no answer from the unit.(Cannot
communicate with the unit.)
The dial-up router is not connected. Or
connected but incorrectly.
The default gateway of G-50A is not set.

If there is no explanation, the unit is not a
compatible type.
In this case, the communication
transmitted from G-50 may not partially be
received. Please remove the check mark
on the Firewall function of the necessary
port. (For detail, please refer to Page 57.)
(If the version of G-50 is more than 2.50,
only [IC] can be searched, even if it uses
FIREWALL. However, [OC] reference
cannot be performed. Moreover, since
other functions cannot operate normally,
please be sure to remove a check.)
In this case, please perform "Stop mail
communication" of 3.4 (2), and start a
maintenance tool again after waiting
about 15 minutes.
A recommendation version is 2.50 or
more.
