The figure below shows a category 5e RJ-35 crossover cable (1) between the instrument and the
computer.

The 2601B-PULSE supports Auto-MDIX and can use either normal LAN CAT-5 cables (patch) or
crossover cables. The instrument automatically adjusts to support either cable.
One-to-many connection
With a LAN hub, a single network interface card can be connected to as many instruments as the hub
can support. This requires straight-through network (not crossover) cables for hub connections.
The advantage of this method is easy expansion of measurement channels when the test
requirements exceed the capacity of a single instrument. With only the instruments connected to the
hub, this is an isolated instrumentation network. However, with a corporate network attached to the
hub, the instruments become part of the larger network.
