Parts needed
The following parts are needed for the SAILOR 100 GX ADS:
•1 x 407090C-00501 SAILOR 100 GX System (Master System)
•1 x 407009C-00501 SAILOR 100 GX ADU (Slave Above Deck Unit)
•1 x 407016C-00506 SAILOR 100 GX ACU (Slave Antenna Control Unit)
•1 x 407090C-010 SAILOR ADS Cable Kit (Cable and RF splitters)
The 407090C-010 SAILOR ADS Cable Kit consists of two 75 Ohm RF
cables, two RF splitters/combiners and a keyline-signal splitter cable.
Software revisions needed for the SAILOR 100 GX ADS:
•SAILOR 100 GX: Minimum software version 1.60
•SAILOR GMU: Minimum iDirect firmware version CX7xx_rootfs_rmt_1.5.1.0-131
System overview
A Master ACU and a Slave ACU are defined in the system. The SAILOR Global
Xpress Modem Unit (GMU) is connected to and configured as modem in the Master
ACU. The Slave ACU is configured as a slave unit by selecting the Master antenna as
modem. The GX satellite information is communicated by the GMU to the Master
ACU through an Ethernet cable. The BUC M&C is communicated by the GMU to the
Master ACU through a standard serial cable. The BUC Key Line is controlled by the
GMU through a key-line splitter cable from the GMU to each ACU (Master & Slave).
The switching from one antenna to the other is handled by the Master ACU based on
several criteria, like predefined blocking zones, unexpected blocking or antenna state.
In case the active antenna enters a blocking zone or is blocked by f.ex. a crane, the
Master ACU commands the idle antenna of the dual antenna system to take over and
the system continues to provide network access.
A detailed connection diagram is shown in the following figure.

Installation
To install the dual antennas, do as follows:
Do not power on the GMU; the GMU must only be turned on when
the complete system is ready to perform a One Touch
Commissioning (OTC).
1. Install the Master ADU, ACU, the RX combiner and the GMU as shown in
Figure 2: GX ADS connection diagram.
2. Install the Slave ADU, ACU, the TX splitter as shown in Figure 2: GX
ADS connection diagram.
3. Provide the vessel heading in the web interface of the Master ACU and Slave
ACU,see NMEA 0183 connector in SAILOR 100 GX installation manual (98-
141779), chapter 4.
4. Connect the cables as shown in Figure 2: GX ADS connection diagram and in
the following table.

LAN setup and cabling for management
In GX ADS “Bridge LAN3 to LAN1” on master and slave. The Master ACU can be
accessed on LAN port 1 & 3 IP:192.168.1.2 and the Slave ACU on LAN port 1 & 3
ip:192.168.1.102. Connect the management device to LAN 3 on slave. See Figure 3: GX
ADS LAN cabling.

1.3.1 Dual antenna mode
Prerequisites
Before setting up the dual-antenna system set the following items:
1. Make a GX Modem profile configuration (on Master)
2. Make a Satellite profile using the GX Modem profile (on Master)
3. Make a Dual Antenna Master Modem profile (on Slave)
4. Make a Satellite profile using Dual Antenna Master Modem profile (on Slave)
5. Make an azimuth calibration for each antenna. This can be done by manually
entering GSC information.
6. Make a Tx cable calibration for the Master antenna system and for the Slave
antenna system.

Task overview for setting up a dual-antenna system
Setting up a dual-antenna system consists of the following tasks:
1. Toconfigure the Master ACU
2. Toconfigure the Slave ACU
3. Toset up blocking zones for dual antenna setup
4. Tomake an OTC for ADS systems
The tasks are described in detail on the following pages.
Switching between Master and Slave antenna
On the DASHBOARD of the web interface, in the lower right hand corner, there is
a hyper link which you can use to jump between the DASHBOARD of the Master
and Slave antennas. Here it is also possible, like in the top bar, to see if the you are
on the Master or Slave antenna and if the antenna is Active or Idle.
The dual-antenna system switches between the 2 antennas in the following scenarios:
•When in a programmed blocking zone.
•When the signal of the active antenna is blocked, whereby the tracking signal is
reduced to at least 4dB below the idle antenna.
•ADU is malfunctioning.
In the statistics report you can get more detailed information on the dual-antenna
mode.

1.3.2 Toconfigure the Master ACU
The Master ACU is configured exactly the same way as a stand-alone SAILOR 100
GX VSAT system with satellite and modem profiles.
On the network settings page select “Switched with port 1” for LAN port 3.
To activate the ACU to be a Dual Antenna Master do as follows:
1. In the web interface, go to SETTINGS > Dual antenna.
2. Select Enable and click Apply.
This SAILOR 100 GX is now ready to act as Master ACU.
1.3.3 Toconfigure the Slave ACU
The Slave ACU must be configured to use the Master ACU as a VSAT modem. The
VSAT modem profile must point to the IP address of the Master ACU, which is the IP
address 192.168.1.2 of the LAN port to where the Master/Slave communication cable is
connected. The Slave antenna IP for LAN port 1 is automatically configured to
IP:192.168.1.102.
On the network settings page select “Switched with port 1” for LAN port 3.
To activate the ACU to be a Dual Antenna Slave do as follows:
Figure 5: Setup of the Master ACU

Configuration of the SAILOR 100 GX
1. Add a specific VSAT modem profile for dual-antenna mode, go to
SETTINGS > Satellite profiles > VSAT modem profiles > New entry.
2. Enter the profile name, for example Dual Antenna Master.
3. As modem select Dual Antenna Master.
4. IP address: this is the IP address of the LAN connector at the Master ACU
(LAN1 always 192.168.1.2) which is used for modem communication.
5. Click Apply.
6. Add a satellite profile that uses the modem profile Dual Antenna Master, go to
SETTINGS > Satellite profiles > New entry.
7. Enter the satellite profile name, for example: Dual Antenna Master.
8. As modem profile select Dual Antenna Master.
9. Click Apply.
10. Go to SETTINGS > Satellite profiles.
11. Click Activate to activate the satellite profile Dual Antenna Master.

1.3.4 Toset up blocking zones for dual antenna setup
It is recommended to define the following 3 types of blocking zones in each
SAILOR 100 GX system:
1. Actual blocking zones on the vessel (No TX)
2. Switching blocking zones (TX allowed), zones leading up to actual blocking
zones, allowing the system to switch antenna before any actual blocking is
encountered.
3. Personnel safety zones (No TX), a type of blocking zone securing safe passage
without the risk of entering VSAT RF radiation.
1.3.5 Tomake an OTC for ADS systems
The entire system is now ready for operation.
1. Turn on the GMU power.
The first time the GMU is turned on it will perform an OTC both on the Master
and the Slave antennas. During this process the GMU will restart several times
before pointing towards the satellite and establish the link.
2. Be patient. The OTC procedure will take at least 16 minutes.
Interrupting the process before it has completed will cause the process
to restart.
3. If for some reason you make a TX cable calibration again, the system will request
the operator to initiate a manual OTC procedure. You can start the OTC procedure
from the GMU dashboard.
