PURPOSE
( full specifications are in the manual for the device )
1. The RS232/BELL202 interface converter is designed to transmit a signal in the BELL202 standard as modem via a dedicated two-wire line in half-duplex mode and a power supply voltage driver for peripheral devices
2. The converter is used to organize the exchange of digital information between the PC and the converters-correctors PC-2, FLOUCOR, PM-3V and digital measuring sensors supporting “Open field HART-protocol”.
3. The transmitter is not a measuring instrument.
