Description:
The Electrical DIR Interface Module is designed for use in the Technisys Universal Modular Chassis (701073-XX). This electrical interface module interfaces unframed serial to parallel electrically. Serial I/O is at STM-1 (155.520 Mbps), E4 (139.264 Mbps) or E3 (34.368Mbps) rates via 75 Ohm SMB connectors or NRZ at ECL levels through 50 Ohm SMB connectors. Serial interface through 75 Ohm connectors is transformer couple line interface, which meets appropriate telecommunication standards. Parallel interface is made through 25 pin sub-mini D connectors. CLOCK OUT is available through a 50 Ohm SMB connector.


Parallel I/O consists of 8 DATA bits plus CLOCK and (3) additional signals; TAPE SYNC, FRAME SYNC and ERROR. Front panel controls and indicators include data rate select, CLOCK OUT SELECT and RECORD and PLAYBACK status indicators. SERIAL or PARALLEL mode and LED ON/OFF are select by toggle switches located on the front panel. SERIAL or PARALLEL mode and LED ON/OFF are select by toggle switches located on the front panel. Fiber optic I/O can be changed to multi mode and other wave lengths, if desired.
