ETHERNET CONNECTIONS
The DSA 3017/3018 has provisions for 10Base-T or 10Base-2 Ethernet connections. The DSA 3217/3218
only supports 10Base-T.
10Base-2
The 10Base-2 connection is a BNC connection. Each module is provided with a BNC-T connector
and a 50 ohm terminator. Modules configured for 10Base-2 are connected in a multi-drop
configuration. Each module has a BNC-T connected at the BNC connector. A coaxial cable is run
from the host computer and connected module to module. A 50 ohm terminator must be connected
to BNC-T connector at the host computer and the last module in the string. The maximum number
of module that may be connected on a 10Base-2 string is 1024. The minimum length of coaxial
cable between modules is 0.5 meters. The maximum length of the 10Base-2 string is 1.5 kilometers.
It is recommended that IEEE 802.3 coaxial cable (Belden-E 82907 or equivalent) be used, but RG-
58 coaxial cable will function correctly.
10Base-T
DSA 3017/3217 series modules use a standard Category 5 RJ45 connection. Shielded Category
5 cable is recommended. All DSA3018/3218 modules use a Bendix connector at the module, which
must be interfaced to the standard RJ-45 connector. A 10Base-T connection may be straight
through(pin to pin) or crossover. A straight through cable must be used if the module is connected
to a hub. Crossover connections are used if the module is connected directly to the host computer.
It is recommended that shielded Category 5 cable be used for 10Base-T cables.
