To connect the Series 3700A 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).
Figure 30: Series 3700A GPIB connector
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.
Ethernet connection
Connect the ethernet connector between the rear panel of the instrument and the host computer or
network router. You can use an LAN crossover cable (RJ-45, male/male) or straight-through cable.
The instrument automatically senses which cable you have connected.
The TSP-Link
®
connectors will accept a LAN connection, but will not be identified as a LAN and will
not connect properly. Be sure to connect the LAN connector correctly.
Use this RJ-45 connector to connect the instrument to the local area
network. When connecting directly to a computer, a crossover cable
(included) must be used. When connecting to a network switch, router, or
hub, a normal CAT-5 cable (not provided) should be used unless your
equipment has Auto-MDIX capabilities. If it does have Auto-MDIX, the
crossover cables may be used.
