Informações

Key features of the Model 707A 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.
