4.3.1 Setting the IP Address

Before you can operate the sat-nms ACU-RMU, you need to set the ACU's IP address. There is a special configuration program on the documentation CD shipping with the ACU for this purpose. We recommend to configure the ACU's TCP/IP settings before you install the sat-nms ACU-RMU at it's final place. To configure the ACU, the following equipment is required:

• The sat-nms ACU-RMU itself.
• 230V AC power at connector J2.
• A Computer running a Microsoft Windows operating system equipped with CD-ROM drive and Ethernet network card.
• A CAT5 crossover network cable or an Ethernet hub and standard network cables to connect the ACU and the computer.
• The CD-ROM shipping with the sat-nms ACU-RMU.

Setting the ACU's IP parameters now is easily done within a few minutes.

1. First install a network cable between the ACU and your computer. If you have a crossover cable available, this is very easy: simply put the cable into the network connectors of computer and ACU. Without a crossover cable, you need to connect both, the computer and the ACU to the same network hub using two standard network cables. It is essential, that the computer and the ACU are connected to the same network segment, the configuration program is not able to find the ACU through routers or network switches.
2. Now power on your computer and connect the ACU to the 230V AC supply (J2). Take care, that circuit breaker F3 inside the sat-nms ACU-RMU is switched to on state, the other ones have to be switched off.
3. Insert the CD-ROM into the computer's drive and inspect it's contents through the 'My Computer' icon on your desktop. Double-click to the 'ChipTool.exe' program in the 'ChipTool' directory.
4. When the ChipTool program is running, the program shows a list containing at least one entry describing the actual network parameters of the sat-nms ACU-RMU.
5. The serial number of the core module shown in the first column of the list. If the list stays empty, the ACU is not connected properly. If there are more entries in the list, the configuration program has found other devices in this network segment which use the same technology.
6. Now open with a right-click the sub-menu IP configuration to open the IP configuration window of the program. In this form the ACU's MAC address is shown on top, below you find the fields to configure the new IP address and network mask. If the ACU later shall be operated through a router, enter the address of the router on the gateway field, otherwise leave this field blanc. Be sure, that the 'DHCP' mark is unchecked, the other values have to be set as shown on the picture. Finally click to the 'Yes' button to set the new parameters at the ACU.

Now the IP configuration of the ACU is completed. You may finally want to test if the ACU is reachable now. Start your web browser and type the ACU's IP address into the URL field of the browser. The ACU should reply with it's main page, provided that the ACU and your computer are configured for the same subnet.
