Section 5-7
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).
• RAI Board : Rear Analog Interface Board have connectors for peripheral device interfaces. Analog
RGB signals for color printer and S-VHS in/out and audio in/out signal for the VCR recording and
playback. Audio output signal for speaker in the monitor are controlled by the signal switching circuit
in this RAI board. If the microphone enable button is turned on, the sound output for speaker might
be turned off automatically to avoid the howling. The sound control signal comes from the VIC assy
in the BEP.
• RDI Board : Rear Digital Interface board have connectors for digital signal interface
