DM240XR High-Speed Digital Modulator TCP/IP Ethernet Setup
MN-DM240XR– Revision 12 B–3
set to a foreign address. Broadcast and loop back addresses will not be allowed. Router not used
example: Router IP Address setting: 010.000.001.001.
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
B.3 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= DM240
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
B.4 Ethernet Test
B.4.1 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.
DM240 Ethernet Network Connection
B.4.2 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,
