CONNECTING IP HOST COMPUTERS
1. Connect your Ethernet Transceiver to the Data Advantage using the DB15 AUI Ethernet port on the rear of
the Data AdvantageVME Chassis.
2. Connect your Ethernet Cable to your Ethernet Transceiver.
MODIFYING THE CONFIGURATION OF HOSTS
For most computers, a routing entry must be added to instruct the host computer to use Data Advantage as the
next gateway for the IP Network ID assigned to the EDACS Network. Symbolic names can also be defined as
desired for the Data Advantage CAP External Address, radios, and groups. These changes will normally be made
by the System Administrator of the host computer(s). The following example commands will work on most
UNIX (trademark of UNIX System Laboratories, Inc.) systems. Refer to the host computer's documentation for
the actual commands.
Assuming that the CAP External Address had been assigned to 1.0.15.14, the following statement could be added
to the /etc/hosts file to assign a symbolic name to Data Advantage Ethernet Network Interface.
1.0.15.14 da_gateway
Assuming that the EDACS IP Network ID had been assigned to 128.1.0.0, the following statement could be
added to the /etc/rc.local file to route all messages destined to radios or groups through Data Advantage.
route add net 128.1.0.0 da_gateway 5
If the customer network contains routers between the Hosts and Data Advantage, the routers and the Hosts will
need updated routing information. Normally, the administrators of the customer’s network are involved in
planning the network and making the routing changes.
TIGHTENING THE DATA ADVANTAGE'S PASSWORD SECURITY (OPTIONAL)
Data Advantage comes with three user id's installed; "root", "user", and "guest". The passwords for these user
id's are the same as the user IDs. All of the user ids and passwords are in lower case. The passwords can be
changed using the "passwd" command. See the Data Advantage User's Reference Manual for more information.
CONNECTING THE DIAGNOSTIC TERMINAL
A VT100 compatible terminal with a power cord and a terminal interface cable is included with the Data
Advantage equipment. To connect the terminal to the Data Advantage VME Chassis, perform the following:
1.
Attach the female connector of the terminal interface cable to the Modem connector on the terminal
(refer to the terminal user's manual for location).
2.
Attach the male connector of the terminal interface cable to the SERIAL PORT 1/CONSOLE connector
on the rear of the Data Advantage VME Chassis.
3.
Turn on the power to the terminal per the instructions in the terminal’s manual.
4.
Verify that the terminal is in VT100 emulation mode via the setup screen. Change and save the setup if it
isn't.
5.
Set the tabs to a tab every eight columns via the setup screen.
