Rear Panel

CardioMD Series III systems have a connector panel on the rear side of the table console. See
Figure 3.12 on page 3-17.
ECG Gate Power Supply
An ECG gate can be supplied from this 115 V AC output. The output is protected by a circuit
breaker. A green LED in the panel shows the status of the 115 V output, which also supplies the
acquisition PC.
ECG Trigger
The ECG Trigger connector is used to connect the R-wave trigger signal from the ECG gate. The
gate is connected to the detector EDC boards, where the trigger pulses are detected and embedded
in the FireWire event stream transmitted to the acquisition PC as time references used for the
image framing process.
