Control Box

connector supplies power (24 V        2.1 A) to the Detector and transmits the X-ray generator’s sync signal and Ethernet image data.
3| DXD 2| Connects the Control Box to the Detector B. This connector supplies power (24 V 2.1 A) to the Detector and transmits the X-ray generator’s sync signal and Ethernet image data.

The Control Box supports connection to up to two detectors. One is for a bucky stand and the other is for a table(bed). Hospital X-ray examination rooms are typically equipped with both bucky stand and table type detectors. This makes it more convenient and efficient to use the detectors.

4| AC- IN| Connects the AC power cord.
5| Ethernet| An Ethernet port to transmit images/commands between the Detector and a PC.
6| Sync| Synchronizes the Detector and X-ray generator.
