FEATURES Key features of the Model 707 Switching Matrix include: • The six-slot mainframe accepts any mix of 8-row by 12-column matrix cards. • Rows are extended within the mainframe to minimize system wiring and interconnect requirements. • Storage of 100 sets of relay setups, which can be uploaded or downloaded through the IEEE-488 interface. • An active front panel LED display shows the current relay status, a stored setup, or an editing scratchpad. • High-speed triggering of stored setups. • Make/break and break/make switching are programmable by rows. Operation is transparent to the user and independent of the relay setup. • With five units connected in a master/slave configuration, the maximum matrix size is eight rows by 360 columns (2880 crosspoints on one IEEE-488 address). • An optional light pen is available for interactive controlling of relay states, editing stored relay setups, and selecting make/break and break/make rows.
