Antenna
Description
This menu is differently shown in the Primary Antenna's AptusNX and the
Secondary Antenna's AptusNX.
To clearly distinguish the primary antenna and the secondary antenna, enter a
description to each antenna.
• Primary: you can enter the description in the primary antenna's AptusNX
(Editable). This menu is not shown in the secondary antenna's AptusNX.
• Secondary: you can enter the description in secondary antenna's AptusNX
(Editable). This menu is only verified in the primary antenna's AptusNX (Read-
only).
Click the "Apply" button to apply the settings to the system. Then perform the
"iARM Save & Reboot" on page 79.

Switching
Threshold
When two antennas are in Tracking mode and have no blockage, the allowable
value will apply for the automatic switching.
• Signal Level: if the signal level is less than the set value, the active antenna is
automatically switched (Default: 30).
• Switching Time (sec): if the difference value of signal between the active antenna
and inactive antenna is more than the set value which is set in the "Signal Level"
menu and maintained the difference value for a set time, the active antenna is
automatically switched. Set the switching time value (Default: 5).
Click the "Apply" button to apply the settings to the system. Then perform the
"iARM Save & Reboot" on page 79.
6
Role
Assigns the antenna's role of the primary antenna or secondary antenna.
• Primary: when running the master ACU which connected to the modem and
the gyrocompass, select the primary role. The master ACU is assigned and
operated as the primary antenna, which will communicate with the target
satellite.
• Secondary: when running the slave ACU, select the secondary role. The
secondary ACU is assigned and operated as the secondary antenna, which
will be on standby and ready to assume primary antenna role to provide better
service in tracking failure and low signal level status.
Click the "Apply" button to apply the settings to the system. Then perform the
"iARM Save & Reboot" on page 79.

Network
to connect
secondary
antenna
Sets the primary antenna's network information to transmit to the secondary
antenna.
• Primary Server IP: enters the server IP address (Default: 192.168.205.1).
• Primary Server PORT: sets a server port number for the primary antenna
(master) and the secondary antenna, which must be the same number (Default:
50205).
• IP: when the antenna role is primary, enter the same IP address with the
"Primary Server IP". When the antenna role is secondary, enter the different
IP address with the "Primary Server IP" but it must be assigned to the same
network class as the primary (Default: 192.168.205.1).
• Netmask: the primary and secondary netmasks must be the same (Default:
255.255.255.0).
Click the "Apply" button to apply the settings to the system. Then perform the
"iARM Save & Reboot" on page 79.
CAUTION
CAUTION
When using Dual Antenna System, the "IP Address" of the "Modem Port Configuration" for the
Primary ACU and the Secondary ACU must be specified differently. Refer to the "Modem/BUC
Setting" on page 95. If you specified the same IP address, the system is not connected to a
modem and can not use a dual antenna system function.
