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)
