NOTE
To avoid possible damage, do not stack more than
three connectors on any one instrument.
Connect the Model 595 to the cable as follows:
1. Line up the connector on the cable with the connector
on the rear panel of the instrument. Figure 4-4 shows
the IEEE-488 connector.
2. TXhten the m securely, but do not overtighten them.
3. Add additional connectors from other instruments as
required.
4. Make sure the other end of the cable is properly con-
nected to the controller. Some controllers have an
IEEE-488 type-connect& while others do not. Corisult
the instruction manual of your controller for the proper
connecting method.

NOTE
The IEEE-488 bus is limited to a maximum of I.5
devices, includinz the controller. Also, the maxi-
mum cable length is limited to 20 meters, or two
meters times the number of devices, whichever is
less. Failure to observe these limits may result in
erratic bus operation.
Custom cables may be constructed by using the informa-
tion in Table 4-l and Figure 4-5. Table 4-l lists the contact
assignments~ for the various bus lines, while Figure 4-5
shows contact assignments.
