Keithley 708B Reference Manual page 25

Section 2: General operation
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.
Connect the TSP-Link cable
Connect the TSP-Link connector to one of the TSP-Link connectors on the rear panel of the
instrument.
The location of the TSP-Link connectors on the instrument are shown below.
For an example of setting up a TSP-Linked system, see "Working with a Series 2600A" in the Models
707B and 708B User's Manual.
