5-10-4 Output Signals
Several signal are fed from the Internal I/O board to an External I/O board located on the rear of the 
system. This board 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.
• An Ethernet signal from the BEP is fed to an Ethernet connector. It is used for connectivity, including 
DICOM Network.
Section 5-11
Peripherals
A VCR, an analog or digital Black-and-White Video Printer and an analog or digital Color Printer may 
be installed on the scanner. These devices receive video signals from the Internal I/O Board and power 
from the AC Control Box.
Peripherals are gemerally specified and approved regionally.
BT’02 (BEP 2.1 and above) systems have digital peripheral capabilities through USB or USB To SCSI 
converters. Table 5-31    Output Signals
