MaxStream Ethernet RF Modems – Networking and Security
- Connect a cross-over cable from the PC to the MaxStream 9XTend Ethernet RF Modem.
- A method for programming this modem is through the use of ARP commands. ARP is an acronym for address resolution protocol.
- The first step is to assign a static IP address to the MaxStream 9XTend Ethernet RF Modem.
- In Windows XP, select Start, then Run. Type cmd and click OK.
-
The command prompt window will appear.
-
Type the following at the c prompt –> ARP -S 10.1.110.11 00-20-4A-8C-BD-9D
-
The ARP-S adds the host by associating the IP address with the physical address (MAC address).
-
10.1.110.11 is the static IP address, followed by the MAC address as shown on the modem 00-20-4A-8C-BD-9D
-
Press Enter
-
At the new c prompt type –> TELNET 10.1.110.11 1
-
Press Enter
-
The additional 1 establishes a connection and a response will appear on the screen…. Connecting to 10.1.110.11 1……Could not open communication to the host. on port1: Connection failed
-
At the c prompt type –> TELNET 10.1.110.11 9999
-
Press Enter
-
The 9999 opens the setup window. 9999 represents the IP side. 14001 the serial side
-
Select 0
-
Select N, 0 and N
-
Select 9 to save and exit.
-
ARP -A command confirms the IP address of the MaxStream Ethernet RF Modem.
-
If the ARP -A command does not confirm the new address, recommend turning off the computer’s firewall.
