Information
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.
