11. When asked to set the Gateway address, if it is not
needed, or if it is using DHCP, type N [ENTER].
If it is needed, type Y and the gateway IP address
as: 190.200.128.1 [ENTER].
The Gateway IP is only needed if using a
Wide Area Network (WAN). In a Local
Area Network (LAN), typically the
Gateway is not needed.
The following displays:
If the Netmask needs to be changed from the

See your network administrator for more
information.

If you want to assign a name for this device for use
on a LAN, type Y and enter up to 16 characters
and [ENTER]. Otherwise just press [ENTER].
If planning to use RPS over a network
through this device, a unique name must
be entered here. This name should be
known to the person who is programming
the panel.
If no DHCP device name is entered, a
default name of Cxxxxxx is used (where
xxxxxx is the last six digits of the MAC
address).

entering a password or press [ENTER] to leave at
default of “No.”
This screen shows the Setup Mode screen you saw

factory and reconditioned.
