LAN cable connection
The Model 2450 includes two Model CA-180-3A cables (LAN crossover cables). One cable is for the
TSP-Link
®
network and the other cable is for LAN communication. However, you can use any
standard LAN crossover cable (RJ-45, male to male) or straight-through cable to connect your
equipment. The instrument automatically senses which cable you have connected.
The following figure shows the location of the LAN connection on the rear panel of the instrument.
Connect the LAN cable between this connection and the LAN connector on the computer.

You can connect the instrument to the LAN in a one-to-one, one-to-many, two network card, or
enterprise configuration, as described in the following topics.
One-to-one connection
With most instruments, a one-to-one connection is done only when you are connecting a single
instrument to a single network interface card.
A one-to-one connection using a network crossover cable connection is similar to a typical RS-232
hookup using a null modem cable. The crossover cable has its receive (RX) and transmit (TX) lines
crossed to allow the receive line input to be connected to the transmit line output on the network
interfaces.

The Model 2450 supports Auto-MDIX and can use either normal LAN CAT-5 cables (patch) or
crossover cables. The instrument automatically adjusts to support either cable.
