Fiber Optic Cables

Communication between PCI cards within the computer and the terminal boards inside the Panoramic X-ray machine is by way of fiber optic cable. These cables can be damaged, broken, misconnected or lost during a move. They are very seldom repairable.

The circuitry in a fiber optic cable uses infrared light to transmit data. Some cables (e.g. handmade cables) transmit visible light. The presence of visible light doesn’t mean that data will be transmitted and received successfully. Sometimes the connectors are not aligned perfectly, or some other factor causes it to not work. A minor fracture in the fiber might allow light to pass but scrambles the transmission enough to cause an error. Some systems might deliver a “CCD error.”

If the communication between your X-ray machine and computer is not working or you are seeing an error message, you may need a new cable. Some application sites may use a single fiber cable for decades. Other sites might need to replace them regularly.

Proper Connection with PCI Card

When connecting a fiber optic cable to a PCI card in the computer, be careful to align the spline with the slot. Once aligned, the outer collar is turned or twisted until it can be pushed in and locked (approximately 1/8^th turn).

To remove the connector, push the knurled metal into the receiver and twist counter clockwise. The cable can then be pulled away from the receiver. If it is jammed – be careful! The plastic receivers can be broken or pulled off the circuit.
