Key features of the Model 708 Switching System are: • The switching system accepts one 7X7X switching card (front or rear panel installation). • Digital I/O contained in the switching system (sixteen inputs and outputs with internal pull-up resistors). • IEEE-488 bus or interactive programming. • 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 present relay status, a stored setup, or an editing scratchpad. • High-speed triggering of stored setups. • Make/break and break/make switching programmable matrix by rows. Operation is transparent and independent of the relay setup. • Maximum matrix size of 8 rows by 60 columns (480 crosspoints on one IEEE-488 address with five units connected in a master/slave configuration). • Sealed construction, low heat producing design eliminates vent holes, which is suitable for cleanrooms. • An optional light pen is available for interactive control of relays and editing stored relay setups.
