External I/O (Rear Panel)

The External I/O is the interface between the scanner and all external items, located at the rear side of
the scanner.
Examples: InSite, TCP/IP network, Printer, etc.
Rear Panel assy consist of 2 assy, RAI and RDI. RAI means Rear Analog Interface and RDI means
Rear Digital Interface. Those are the rear-panel assemblies which interconnect external signals and
power with the LOGIQ 5 system. Both of the assemblies are the same except the circuit breaker's
current ratings depending on voltage of the system power source (See Safety described below).
