Magneto-Optical Drive (MOD)
The MOD is used to back-up images and reports. Backing up enables storage of the images and reports
for future review on Vivid 3N
ultrasound units, or other EchoPAC-compatible devices. The MOD is
controlled by the CPU via the SCSI Card. Only 2.3 MB media are EchoPAC (DICOM)-compatible with
EchoPAC devices. Magneto-Optical media of any other size may be used for back-up, but will only be
compatible with DICOM.

CD Read Write (CDRW)
The CDRW is used to back-up images and reports, in the similar way as the MOD. In addition, the CD
is used as the main source of software upgrades and other service utility operations. The CDRW can
write to 24X speed CDs or above, and can read all types of CDs. The CDRW is controlled by the CPU
via the IDE Bus.

ECG Module
The ECG Patient I/O module is used to track and convert the ECG signal either via Internal ECG leads
or External sources. In addition, the ECG module provides an interface to Microphone input and
FootSwitch pedal. The Foot switch is a pass-through to the keyboard functions, while the other functions
are communicated to the BEP via the Com2 serial port of the BEP. The Internal leads of the ECG are
optically isolated to fit FAD standards.
