Ethernet Connection - Ten-Tec OMNI-VII 588 Programmer's Reference Manual

the other device is a DTE, then you will need to use a standard straight RS232 interface
cable.
In order to use the OMNI-VII in remote mode, but you intend on controlling the rig
only by the serial port, then it is suggested that you disable the Ethernet activities of the
OMNI-VII. Setting the first octet of the G8WAY IPADDR to 0 disables Ethernet
activities.

Ethernet Connection

The Ethernet interface on the OMNI-VII is handled via a Realtek RTL8019AS Full
Duplex Ethernet Controller located on the DSP/Logic board. This Network Interface
Controller (NIC) is fully compliant with Ethernet II and IEEE802.3 10Base5, 10Base2,
and 10BaseT. The full-duplex function of the NIC enables simultaneously transmission
and reception on the twisted-pair link to a Full Duplex Ethernet switching hub. This
feature not only increases the channel bandwidth from 10 to 20 Mbps but also avoids the
performance degradation problem due to the channel contention characteristics of the
Ethernet CSMA/CD protocol. This connection is configured for 10Mbps, so it is
compatible with all 10/100 networks.
Depending upon how you want to connect your OMNI-VII to another computer via
the Ethernet Interface, there are two types of cables that you can choose. If you
remember, for serial communications, you either pick a standard serial cable or a null-
modem serial cable. The same is true in principle for Ethernet connections. If you are
going to connect the OMNI-VII directly to a computer, then you will need to use a
"cross-over" Ethernet patch cable. If you are going to connect the OMNI-VII to a hub or
router or gateway, then you will need to use a "standard" Ethernet patch cable.
In either case, you can use either a CAT-5E (350Mhz) high-speed patch cord, or you
can use a CAT-6 Networking Cable. Either will satisfy the bandwidth requirements of the
OMNI-VII. They both follow EIA/TIA 568B Wiring, and are equipped with RJ-45
connectors.
