The FI7000 interface provides both power to and serial communication with the FL/PL 7000 series probes. An additional, low-level loop back fiber optic connection is used to sense unexpected disconnect of laser driven fibers to ensure user-safe operation. As an additional safety measure, shuttered connectors are used on all fiber optic connections to and from the probe. The FI7000 can be used with the FM7004 Field Monitor (using the provided 0.3 meter fiber optic cable) or a PC by direct communication using the USB, GPIB, or RS-232 interfaces.
