FOTEMP MINI OEM Signal Conditioner Connecting the TS Temperature Probe The FOTEMP MINI optical interface is via an ST Pigtail. There are two fibers terminated internally in the ST plug. Use the supplied MR320A ST Bulkhead Adapter to connect TS sensor probe to the FOTEMP MINI signal conditioner. -
Page 11: Serial Communications
FOTEMP MINI OEM Signal Conditioner Serial Communications Introduction to UART Operation and Data Frame The FOTEMP MINI is designed for embedding into the user’s design via a simple 3-wire UART-based half-duplex serial interface. UART stands for universal asynchronous receiver / transmitter and defines a protocol, or set of rules, for exchanging serial data between two devices. -
Page 12: Fotemp Ascii Serial Protocol
The FOTEMP Signal Conditioners use a standard ASCII protocol across its Serial (TTL and RS232) and USB interfaces. The detailed command and response protocol are described in Micronor Sensors Application Note AN123. In summary, the FOTEMP MINI recognizes the following commands:... -

Page 17: Fotemp Mini Theory Of Operation
MICRONOR SENSORS FOTEMP MINI OEM Signal Conditioner FOTEMP MINI Theory of Operation As shown in Figure 10, the FOTEMP MINI operates on the same theory of operation as the FOTEMP signal conditioners. Figure 10. FOTEMP MINI Theory of Operation As shown in Figure 11, GaAs-based fiber optic temperature probes and FOTEMP signal conditioners are deployed wherever conventional convention thermocouples cannot be used. -
