Operation and Control using the Simplex Parallel Interface (SK/SP Emulation Mode)

The Simplex Parallel Interface (Emulation Mode)

The Simplex parallel interface is fully backwards compatible to the interface used on the SK/SP
Series Fiberoptic switch. It also provides a simple interface when the advanced features of the SKB
are not required.
The interface permits channel numbers to be strobed in using the STROBE line. As a reference for
SK/SP users, the typical method of interface to a host controller for the SK/SP Series Fiberoptic
Switch is shown below for reference.

Simultaneous operation of serial and parallel interface is not supported.

Simplex Parallel Interface: Pin Functional Description

Data Lines (D0 to D6)

Valid channel numbers are strobed in through the data lines on high-to-low transitions of the /Strobe
line. When a new channel is strobed in, the SK switch immediately selects the channel. The channel
