S.I. Tech, Inc. Asynchronous Optical Bit-Driver® 2005 SM

Model 2005 Bit-Driver is an asynchronous simplex or full duplex system capable of transmitting data at operating speed from 110 bps to 56 Kbps over fiber optic cable. Fiber optic cable offers the advantage of small size, light weight and complete electro- magnetic freedom from the problems of EMI/RFI to its maximum operating range of up to 6600 feet. Totally dielectric fiber optic cable is immune to high voltage and lightning. This compact asynchronous system can help you transmit data in-house or in other short-haul applications through the noisiest operating environments without losing a bit. (Bit error rate ≤ 10E-9) It's a stand-alone component, complete with RS-232 interface, 120 volt power cord plus input and output transmission connections. LEDs are used to indicate the presence of carrier and data signaling over the data path. There is a diagnostic logic probe to verify "high" or "low" status of TD, RD, TSR, CTS, DSR and DCD circuits -- without a breakout unit. Includes null modem switch to configure the modem as a DTE device instantly, and a constant or controlled carrier switch.
