GPIB interface connection
Use a shielded IEEE-488 cable such as the Keithley Instruments Model 7007 to connect the
Series 3700 IEEE-488 connector to the GPIB connector on the control computer. Connect one
end of the cable to the host computer and the other end to the Series 3700. Both cable
connections (see item 1 in the figure titled "GPIB cable") are identical. The GPIB cable
connectors are stackable. For additional non-Series 3700 GPIB instruments in the test system,
daisy-chain a GPIB cable from one instrument to another.
NOTE
To minimize interference caused by electromagnetic radiation, use only shielded GPIB
cables. Available shielded cables from Keithley Instruments are the Model 7006 and
Model 7007.

Standard RJ-45 (Ethernet) interface connection
The Series 3700 uses a standard Ethernet connection configuration. It is designed for a
10/100BaseTX network using standard RJ-45 connectors. This is an eight wire connector, but
only two sets of wire pairs are used: one pair to transmit and one pair to receive data. A
10BaseT network can accommodate transmission speeds up to 10Mbit per second where a
100BaseTX network operates at speeds of up to 100Mbit per second. Both types of networks
usually require Ethernet hubs to make connections. The exception is a one-to-one connection
using a crossover cable, which may be a 10BaseT or 100Bas
eTX dependent on the computer’s
Ethernet interface card and which category of cable is used (the Series 3700 can be directly
connected to a computer's NIC card using an Ethernet crossover cable). Refer to
Rear panel
summary
(on page 3-1) for connector location.
USB connection
Connect a computer controller to the Series 3700 rear panel USB (from host) connector
(connect USB flash drive devices to the Series 3700 front panel USB). Refer to
Rear panel
summary
(on page 3-1) for connector location.
