Standard Ethernet cables are available commercially in many different
lengths. The standard cable is wired pin for pin (straight through) which
means that pin 1 of the connector at one end of the cable is wired to pin
1 of the connector at the opposite end of the cable. This type of cable is
used to connect the DGy 201 directly to the network — typically using an
Ethernet hub or switch. To connect directly from a PC to the DGy 201, a
crossover cable must be used (see the following section for details).

C R O S S O V E R C A B L E S

To connect directly from a PC (such as a laptop) to the DGy 201 without
connecting to the network, an Ethernet “crossover” cable must be used.
Crossover cables are available commercially.

In a crossover cable, one end of the cable is wired as a straight through
cable, using the pin assignments shown in

Table A-2

. At the other end

of the cable, the TX and RX interconnections are exchanged (crossed
over).

Ethernet uses balanced differential signals on twisted pairs of
