The back (bottom) of the SIU5 has a diagram of the box’s functions shown in Figure F-2. The
channel points, trigger port, signal cable port, and power port are all receptacles for cables
that attach the SIU5 to your PC and to your sonar.
Figure F-2. Signal Interface Unit 5 diagram of functionality
The SIU5 can be connected to digital or analog boards, depending on the type of sonar you
intend to use. Examples of sonars that would require a digital interface are the EdgeTech
DF1000, EdgeTech ACI, Klein 2100. Examples of sonars that would require an analog
interface would be Klein 595, EGG 260, Geo Acoustics, and others.
F.2 SIU4 and SIU4-2 Analog Interface
As an external module to Q-MIPS and Isis, the SIU4 provides an interface between the
detected analog side-scan sonar, sub-bottom profiler, boomer, or tape-playback signal, and
the Q-MIPS or Isis analog input.
