Coax Transceiver for 10BASE5

Catalog Number 1785-TR10B5

The coax transceiver lets you connect a device with an AUI interface to a 10

Mbit/s CSMA/CD LAN (ISO/IEC 8802-3, IEEE 802.3, 10BASE5) coax

cable connection via this cable piercing tap.

Description

The 1785-TR10B5 coax transceiver can be connected to the AUI interface

of a device either directly or via an AUI cable. It is connected to the coax

cable by a coax interface.

The transceiver offers these functions according to IEEE 802.3 10BASE5:

• receiving the data at the transceiver interface and sending them into the

coax cable

• receiving the data from the coax cable and sending them to the

transceiver interface

• indication via a yellow LED of data transmission and reception through

the coax cable

• detection of data collisions in the network and reporting them to the

terminal equipment as well as indicating them by a red LED

• ability to enable/disable the SQE test: at the end of every transmit

operation, a short collision signal (heart beat) approx. 1 µs long is sent to

monitor the electronics

• jabber control and display: protecting the network from data packets that

are too long (> 20 ms)
