190 MP System Hardware Guide
FOTS100 Fiber Optic Temperature System
This is a stand alone system, but it can also be interfaced to MP150 or MP100 Systems
via CBL101.
Use with high-accuracy, MRI-compatible fiber optic temperature probes TSD180 or
TSD181.
FOTS100 includes control unit with RS-232 port, ± 5 V analog output, and rubber boot;
power via 9 V
battery or wall power.
