Notes
●
When 15 or fewer GB-50A units are used in the designated network for air-conditioning, it is recommended that
the IP address be set using SW2 on the unit.
● If the set IP address of GB-50A is forgotten, check the IP address that is registered on the monitoring PC (WEB
or TG-2000A). GB-50A can be started by changing the setting of SW2 on GB-50A and using an arbitrary fixed
IP address as a temporary IP address. It is recommended to paste a sticker with the IP address on the unit, so
that the IP address of GB-50A is available at all times. Once GB-50A is started up with a temporary IP address,
a new IP address can be assigned to it on the Initial Setting Web.
