Figure 21 View Interrogator Units menu
For each Interrogator Unit edit the Unit Name, shown in Figure 20, to identify the
Interrogators after installation (e.g. IU 1 Port side). When choosing between different
Interrogators at the installation, select the Interrogator Unit drop down menu. Then choose
which Interrogator to use, and make sure that the Active check box is checked (as shown in
Figure 20).
3.4.3.2 Interrogator mounting angle
The Interrogator's mounting angle has to be calibrated after installation. RADius outputs
direction to the Transponder relative to the vessel's centre line (0 forward, positive to
starboard). The Interrogator is typically pointing backwards on the vessel. If the mounting
angle had been 180 degrees, then the mounting angle in the system configuration box above
should have been 180 degrees. However, the actual installation angle is seldom met exactly
and a procedure to measure the actual angle is shown in Figure 22.
