External I/O
5-8-1 General Description, External I/O
The External I/O is the interface between the scanner and all external devices.
Several signal are fed from the Internal I/O module to the External I/O module. The External I/O module
contains data buffers and a galvanic isolation section.
Different types of signals are fed to connectors accessible on the External I/O:
• R, G, B and Sync are provided for external RGB monitors or printers.
• Composite video, black and white video and S-VHS video are buffered and fed to output connectors
for external monitors and printers.
• Two serial RS-232 ports are provided for external communication with e.g. the System CPU. One
of the RS-232C ports are located inside the scanner, and was intended for use by a modem, the
other is located on the EIO rear panel. These serial ports have never been used on Vivid 7.
• An Ethernet signal from the BEP is fed to an Ethernet connector. It is used for connectivity, including
DICOM Network.
