Using the Ethernet Interface

OS-9/Internet provides utilities for file transfer (FTP) and terminal
connection (TELNET) to remote systems on the network. OS-9/Internet
also provides socket-library functions that you use to write network
client/server application programs.
See the OS-9 Internet Software Reference Manual, publication
1771-6.4.11, for information on FTP and TELNET utilities and OS-9
socket library.
Important: BASIC users cannot reference socket-library functions
directly. The BASIC program must fork another process written in C.
The Ethernet port connects to a thin-wire or a thick-wire (coaxial) network
via a 15-pin transceiver or Medium Access Unit (MAU) connection. The
Allen-Bradley transceivers available for this interface are:
5810-AXMT (thin-wire Ethernet/802.3)
5810-AXMH (thick-wire Ethernet/802.3)
A network with thick-wire coaxial cable can be up to 500 meters (1,525
feet) with up to 100 nodes. Thick-wire cable is referred to as “10base5”
—this means that it has a 10 Mbps transmission rate, baseband, and can be
500 meters in total length.
A network with thin-wire coaxial cable can be up to 200 meters (610 feet)
with up to 32 nodes. Thin-wire cable is referred to as “10base2”—this
means that it has a 10 Mbps transmission rate, baseband, and can be 200
meters in total length.
The control coprocessor connects to the transceiver using either a 2.0 meter
(6.5 feet) or a 15 meter (49.2 feet) transceiver cable, which is also known
as an Access Unit Interface (AUI) cable. The Allen-Bradley cable
numbers/kit catalog numbers are:
Catalog Number Contents
1785ĆTC02/A ThickĆwire 2.0 m (6.5 ft) transceiver cable
1785ĆTC15/A ThickĆwire 15.0 m (49.2 ft) transceiver cable
1785ĆTAS/A (kit) ThinĆwire transceiver and 2.0 m (6.5 ft) cable
1785ĆTAM/A (kit) ThinĆwire transceiver and 15.0 m (49.2 ft) cable
1785ĆTBS/A (kit) ThickĆwire transceiver and 2.0 m (6.5 ft) cable
1785ĆTBM/A (kit) ThickĆwire transceiver and 15.0 m (49.2 ft) cable
To install the cable, attach the cable male connector to the Ethernet female
connector on the control-coprocessor main module. See Appendix C for
more information on cable configuration and pin assignments.
See the Installation Data, Allen-Bradley Ethernet/802.3 Transceiver,
publication 5810-2.1, to connect the transceiver to your Ethernet network.
