MONITOR DESCRIPTION
18 Model 7600/7800 Operation Manual
6.12 Rear Panel Description
The following are located on the rear panel.
MAINS POWER INPUT: A receptacle for a standard ac power cord.
CAUTION: When the monitor is connected to another piece of equipment, always make sure that each piece
of connected equipment has its own separate ground connection.
Do not attempt to connect cables to these connectors without contacting your Biomedical Engineering Department.
This is to ensure the connection complies with leakage current requirements of one of the following applicable
standards: ANSI/AAMI ES60601-1:2005, CAN/CSA-C22.2 No.60601-1:08, and CE-MDD 93/42/EEC. The
maximum non-destructive voltage that may be applied to these connectors is 5V.
SYNCHRONIZED OUTPUT: A BNC type connector with a pulse output synchronized with the peak of the R-wave.
The synch pulse amplitude is factory configurable: 0 to +5V, +5V to 0V, -10V to +10V, or +10V to -10V. Available
synch pulse widths: 1ms, 50ms, 100ms and 150ms.
PEQ GROUND: Potential Equalization - A ground connection that can be used to ensure that no potential differences
can develop between this equipment and other electrical equipment.
FUSE: Replace only with the same type and rating of fuse as indicated on the fuse rating label: T 0.5AL, 250V.
ECG OUTPUT: This is a ¼ inch stereo jack with an ECG analog waveform output on the tip, synchronized pulse
output on the ring, and common on the sleeve. Limit to 100Hz bandwidth.
RS-232: An electrically isolated RS-232 micro-D connector for device communication. The RS-232 connector
provides 6V and -6Vwith a maximum current of 20mA.
AUXILIARY (Model 7800 only): A 9-pin D-subminiature connector that provides a customized interface for
specific installations. The auxiliary output provides +5V and -12V with a maximum current of 12mA.
ETHERNET (Model 7800 Only): This is a two-channel Ethernet output that provides an Ethernet protocol
(10Base-T, IEEE 802.3) from a single RJ45 connector. The first channel connects the Model 7800 and the CT
scanner console to share data and control options. A second Ethernet channel from the same connector provides
ECG data to the CT gantry display.
SERIAL NUMBER LABEL: The serial number label indicates the model and a unique serial number for the
monitor.
WARNING: The use of ACCESSORY equipment not complying with the equivalent safety requirements of
this equipment may lead to a reduced level of safety of the resulting system. Consideration relating to the choice of
accessories shall include:
• Use of the accessory in the PATIENT VICINITY
• Evidence that the safety certification of the ACCESSORY has been performed in accordance with the
appropriate IEC 60601-1 and/or IEC 60601-1-1 harmonized national standard
