The AT-1700 Network Card

10BASE-T, 10BASE2, 10BASE5 or 10BASE-FL Choices

The AT-1700T, BT, AT and FT versions all have an RJ45

receptacle for connection to 10BASE-T network segments. The

AT-1700 is compatible with 100

Ω

Unshielded Twisted Pair

(UTP) or 100

Ω

or 150

Ω

Shielded Twisted Pair (STP) wire. The

AT-1700AT supplements the RJ45 with an Attachment Unit

Interface (AUI) to which 10BASE2, 10BASE5 or 10BASE-FL,

an extension of the earlier Fiber Optic Inter-Repeater Link

(FOIRL) specification, may be adapted by adding the

appropriate transceiver. The AT-1700BT has a BNC connector—

in addition to the RJ45—for direct connection, with T-connector

and terminator, to a 10BASE2 Ethernet segment (thin wire

Ethernet or “cheaper net”). The AT-1700FT includes ST-type

transmit and receive connectors for fiber optic media.

Auto or Pre-Set Port Selection (BT, AT and FT)

An auto port-select option configures the AT-1700BT, AT or FT

to sense which of its two ports is connected. In auto mode, the

factory default mode, the card checks to see if the twisted-pair

port is connected. If not, it attempts to use the other port. The

alternative is to pre-set the port selection using the

CardAssistant configuration menu. In pre-set mode, both ports

can remain connected to network segments of different media.

The active port is the one selected in CardAssistant.

CardAssistant Software Performs Configuration

For setting I/O parameters, the CardAssistant configuration

menu displays all parameter choices. Configuring the card for

your PC workstation or server involves choosing menu options

instead of moving hardware jumpers on the card.
