1. Introduction
The Romantis satellite modem/router can work as an SCPC (Single Channel Per Carrier) modem with the
satellite carrier frequency fixed or assigned on demand. It can also be a mini-hub or a remote station in
a TDM (Time-Division Multiplexing) or TDMA (Time-Division Multiplexing Access) network in which two
or more bit streams are transferred on one channel. This document describes the hardware, software,
and configuration needed to integrate the Romantis modem/router as a standard acquisition source
with the AvL AAQ antenna system.

Figure 1- Modem/Router Indicators and Connections
All the interfaces are located on the rear panel of the device. The indicators are located on the front
panel. LAN Indicators are integrated into the LAN connector on the back of the modem.
2.1. Hardware
The hardware associated with this module is the Romantis Modem and the AvL AAQ Antenna System.
2.2. Software
Path
Main Window → Help→ Version Info
Level 0
Be sure that the Remote Client, ROM, and device module are at or above the versions shown below.

Figure 2 –Version Info.
2.3. Hardware Connection
All wire connections must be performed before powering up the router. The AAQ controller supports
Ethernet communication to the modem. Connect the AAQ antenna controller to the Romantis modem
via Ethernet and connect the Romantis modem Rx (Receive) and Tx (Transmit) ports to the antenna Rx
and Tx ports via coax cable.
2.3.1. Serial Communication Connection
A serial connection is not an option for the hardware associated with this module.
2.3.2. Ethernet Communication Connection
Path
Main Window → File → SettingsAAQ Network Interface Options
Level 1
When setting the system to communicate by Ethernet it is important to make sure the controller has
a network path to the modem so the controller can query the modem over the network. Connect the
AAQ antenna controller to the Romantis modem/router via one of the three LAN ports on the rear of
the CIP (rack mount Control Interface Panel) or through an Ethernet switch.

Figure 3 –Ethernet Setup
Note: Be sure to connect the power to each device. The AAQ Controller should connect to the port
labeled AAQ on back CIP. Romantis Modem should connect to one of the LAN ports on back of CIP.
The modem/router has a static IP Address, in this example the static IP address of the modem/router
is 10.20.20.26. Therefore, communication must be on the 10.20.20.XXX network. These IP addresses
will vary depending on the customer network. The Subnet can be set to 255.255.255.0 to give the
modem/router the widest possible range of IP addresses to assign to other devices while the
Gateway must be set to 192.168.129.1 if the CIP is configured as a router. See the CIP appendix
(Appendix B) for more information

4. Operation
4.1. Functional Overview
When properly configured, the Romantis modem is fully integrated into the AvL AAQ’s acquisition
process, and can be used as a signal source to acquire and track on satellite signals. Once the target
satellite has been found, the modem will log into the network and be ready to send traffic.
4.1.1. Acquisition Process
1. Power up the antenna
2. Command the antenna to acquire
The AAQ will Home and initialize its sensors, it will read the compass, and then proceed to
the first initial scan point
3. The antenna detects a lock from the modem and stops
The Modem has detected the satellite carrier
The AAQ has stopped its scan
4. The AAQ will coarse peak back to the signal
This is the initial coarse peak that will move through the entire beam
5. Once coarse peaking has been completed, fine peaking will begin
This fine peaks the signal using small slow movements
6. AAQ will stop movement
The AAQ has enabled transmit on the modem
The Modem will log into the network and be ready to send traffic
4.2. Sensor Outputs

Once the Sensor Output window is available, enter “Romantis” in the search box. Check the boxes
beside any Sensor Outputs you wish to view for monitoring operations.

to use the Romantis modem
Device window does not display
“Romantis” as Device In Use.
Verify proper installation of the
modem/router module (section
