TM103 – Rev. 2.8 E-3
8. MODEM EADDR: This displays the Modem (Unit) Ethernet Address. The Modem
Ethernet Address is configured at the factory. It is a unique Radyne equipment identifier
Address. Example: 0010650903EB
9. ETHER RATE
: This displays the current Ethernet port data rate. If multiple rates are
available, then a selection can be made to specify the Ethernet port data rate (10BaseT).
Example Ethernet port Data Rate: 10 MBPS/HD
E.2 Network Configuration Summary
If the above steps were followed and the information was entered, then the following would be the
TCP / IP configuration summary for a ‘no router specified’ setup:
1. Boot Mode = NON-VOL
2. Bootp Server Tag = 206
3. Modem Host= DMDXX
4. IP Address Mask = 255.255.0.0
5. Modem IP Address = 172.18.100.215
6. Server IP Address = 172.18.4.250
7. Router IP Address = 010.000.001.001
8. Modem Ethernet Address= 0010650903EB
9. Ethernet Rate = 10 MBPS/HD
E.3 Ethernet Test
E.3.1 Connecting the Modem Ethernet Cable to a Network Link
1. Connect the Network Switch (Hub) to the Modem Ethernet port (J9) using
standard RJ-45 to RJ-45 10BaseT (CAT-5) Cables as shown below.
Ethernet Network Connection
E.3.2 Connecting the Modem Ethernet Cable Directly to a Computer
(without a Network)
The user can directly connect to the equipment without connecting to a network. This will often
occur at remote sites where a network is not available. To connect, the user will need an
Ethernet Crossover (Null) cable. The pinout for this cable is as follows,
RJ45 Connector A RJ45 Connector B
Pin #1 Pin #3
Pin #2 Pin #6
Pin #3 Pin #1
Pin #4 Pin #4
Pin #5 Pin #5
Pin #6 Pin #2
Pin #7 Pin #7
Pin #8 Pin #8
