Figure 11 – Device Window ..............................14 Introduction This document describes the concepts required to use the iDirect module as part of the AAQ Controller. This module directly supports iDirect modems Evolution X3, X5, X7, and the Evolution 8000 Series. It is recommended that older iDirect modems should be upgraded to software version iDX 3.5.
2.3. Hardware Connection Connect the AAQ antenna controller to the iDirect modem through the desired means. The AAQ controller supports serial (RS232) and Ethernet communications to the iDirect modem and can be configured to use either depending on the necessary networking scheme.
2.3.2. Ethernet Communication Connection When setting the system to communicate by Ethernet, connect both the controller and the iDirect modem to the AvL CIP or other network switch so the controller can query the modem over the network. Ensure power is connected to each device.
When setting the system to communicate by Ethernet, it is important to make sure the controller has a network path to the iDirect modem so the controller can query the modem over the network. The example shown below represents a typical installation.

Modem 3.3. Signal Configuration Items The controller polls the modem for signal information that is used to correctly point the antenna. In this case the modem’s SNR value is used to peak the signal at its maximum. The following are recommended settings to ensure the movement of the physical antenna is not faster than the polling speed of the signal data.

Functional Overview When properly configured, the iDirect 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.
