Models 707B and 708B Switching Matrix Reference Manual
To connect the Model 707B or 708B to the IEEE-488 bus, line up the cable connector with the
connector located on the rear panel. Install and tighten the screws securely, making sure not to
overtighten them (the following figure shows the location of the connections).
Connect any additional connectors from other instruments as required for your application. Make sure
the other end of the cable is properly connected to the controller. You can only have 15 devices
connected to an IEEE-488 bus, including the controller. The maximum cable length is either 20
meters or two meters multiplied by the number of devices, whichever is less. Not observing these
limits may cause erratic bus operation.
