The FOI-4451 and FOI-4541 are specially developed to provide complete electrical isolation for RS- 422 communications..The unit maintains transparency to all handshaking protocol and is capable to accept up to a maximum 6.144 Mbps. rate of data and clock signals. FOI-4451 is equipped with a regeneration switch that enables to toggle between synchronous applications that require Send Timing (ST) and asynchronous or synchronous applications that require Terminal Timing (TT). The series can support tail circuit and null modem functions to enable DCE to DCE or DTE to DTE communications that calls for two of the same FOI units. An alternate interface (V.35 or RS-232) installed at the opposite end enables link creation between two electrically incompatible interfaces without the need of a separate interface converter. The units are used in high electrical noise applications or in and out of RF shielded enclosures. The fiber optic cable remains unaffected to interference caused by impulse noise, crosstalk, or EMI.
