5-1-2-2 Settings for when the G-50A is connected to an existing LAN
When connecting the G-50A to an existing LAN, consult with the network administrator who is responsible for the
LAN before setting the IP address, subnet mask, or gateway address.
[ Example of a Permanent LAN System ]

Subnet Mask :255.255.255.0
G/W Address :10.130.1.250
5-1-3 M-NET Setting
In M-NET Setting, set the G-50A M-NET address, whether or not a K-Control unit is present and which machines
send the prohibited controller command.

(2) When K-Control air conditioners are connected, click [in use] in the [K-Control Unit] field and enter the
M-NET address of K transmission converter in the [K Converter] field.
(3) If prohibited controller (prohibiting local operation) has been set, this setting determines the scope of this
setting s control, i.e. operation is prohibited for both the remote control and subordinate system controllers,
or just for the remote control. Click [SC/RC] when you want prohibited controllers to include both subordinate
system controllers and the remote control, or click [RC only] when you only want to prohibit operation on the
remote control.
Note: Normally, you should select [SC/RC].

stop and run multiple air conditioners connected to the G-50A via the separately sold external I/O adapter
(Model: PAC-YG10HA-E) using level signals and pulse signals.
(1) Select [Not in use] when not using the external input function.
(2) Selecting [Emergency stop (Level signal)] makes it possible to stop multiple units by using a level signal.
While this stop operation is being performed, operations such as running or stopping units are prohibited on
the G-50A unit or remote control.
