Checking the IP Address and Subnet Mask of Your Computer
The ipconfig command is a command-line utility available on Windows NT 4.0 and Windows 2000 operating systems.
Open the DOS prompt and type “ipconfig” or “ipconfig/all” to determine the current IP Address and Subnet Mask of the
computer you are trying to connect to the CSM.

If you determine that you need to change the IP address of your computer, follow the instructions in the Connecting Your
PC to the CSM on page 11.
Determining the CSM’s IP Address and Subnet Mask
If you are unsure of the network settings on a CSM, first attempt to connect at the default IP address. The CSM controller is
pre-configured with an IP address in the range 192.168.1.14x and default subnet mask of 255.255.255.0, where x is the last
digit of the CSM’s serial number. The IP address is also listed on the packing slip that accompanies the unit. The previous
installer may have left the CSM at the default settings for convenience.
If the previous installer has gone through the process to change the IP address and subnet mask, he or she was instructed to
write down the new IP address for future use. You should investigate all possibilities for finding the network setting before
starting the lengthy procedure for determining the IP address from the CSM.
If you are still unsure of the IP address, you can use the HyperTerminal program on your computer to read it from the CSM
through a serial connection to COM1 on the CSM.
CAUTION
Exercise caution when using HyperTerminal on the CSM. You must log on to the CSM with administrative
privileges, which means you can change many settings. Modifications you make could have unexpected
consequences, including making the CSM inoperable.
Use the following procedure to directly connect to a CSM using HyperTerminal:
1. Attach an Ethernet patch cable (straight through, not crossover) with standard male RJ-45 (8-wire) connectors to the
RJ-45 connector on COM1 of the CSM.
