JDS Uniphase SKB Manual

This document facilitates operation of the SKB fiberoptic switch module. Note that the
only difference between the SKB variant described by this document and the standard
SKB is the type of connector. Information concerning pin assignment of the SKB should
be taken from this document only. Please disregard the information on this subject
contained in the SKB user's manual. Should you have any questions regarding the
following information, please contact JDS Uniphase directly at (613) 727.1303, or by fax

Functional Notes
1. The SKB can be operated as an SK switch. Refer to notes in this document
describing SK emulation.
2. The pins allocated to SK emulation are located in the center portion of the 2x25
connector allowing direct ribbon cable drop-in to existing applications.
Pin Assignment
The SKB switch pin assignment has been updated from the existing SK switch pin
assignment, the primary differences are as follows:
1. D7 will be added to the interface.
2. /SOP and R/W will be added to the interface.
3. /RESET now called HOME.
4. /RESET added to provide a hardware reset.
