Switch-selectable DTE/DCE

The Async Fiber Optic Mini Modem features a switch- selectable DTE/DCE option. This allows operation as DTE, for connection to another DCE such as a multiplexor port, eliminating the need for a cross cable.

Continuous or switched operation

The carrier can be strapped for either continuous operation or switched operation, controlled by the RTS signal, for transfer of a control signal end-to-end.
