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™ 4 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.

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.

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.
