4. Connect CallFinder to Ethernet Network
Plug one end of your RJ45 Ethernet cable into the CallFinder’s Ethernet jack (labeled “10/100”) and the
other end into your network Ethernet hub. This Ethernet cable is not included with your CallFinder unit.
Note: Before connecting to the Ethernet Network, make sure that the network to which you are
connecting the CallFinder is not a 192.168.2.x subnet.
If it is a 192.168.2.x subnet, it may clash with the CallFinder because the CallFinder’s default IP
address is 192.168.2.1. To correct this, connect an RJ45 cable directly from the Admin PC to the
CallFinder until the CallFinder’s IP address has been configured. Then connect the CallFinder into
the network.

5. Connect CallFinder to DID Lines
Plug one end of the phone cable into the CallFinder’s Channel 1 DID jack and the other end into an
analog DID trunk line jack. The DID Line cable is included with your CallFinder.
Caution: Never plug the DID connector into a standard POTS Line. This may damage the CallFinder or
the central office equipment. Use only an analog DID Line.
Repeat for the CallFinder’s Channel 2 DID port.
6. Identify CallFinder’s Extension Ports (FXS/FXO) for Later Hookup
Caution: You must wait until after the CallFinder software has been configured before connecting the
cables between the CallFinder’s Extension (FXS/FXO) Ports and the PBX. Because the
CallFinder and the PBX can both supply battery power, the cable connections must be done
properly. Otherwise equipment damage could occur.
Before making connections to the CallFinder Extension (FXS/FXO) channels, you must know the type of
PBX port to which each CallFinder port will be connected and set the “Extension Port” field in the
CallFinder Channel Configuration screen appropriately.
• When connecting to a PBX Station Port, set the CallFinder channel to FXO.
• When connecting to a PBX Trunk Port, set the CallFinder channel to FXS.
• When connecting to a FaxFinder fax server, set the CallFinder channel to FXS-Pass-Through.
When the Channel Configuration | Extension Port software field has been set properly for both
CallFinder channels, you can proceed to connect the cable between each of the CallFinder’s FXS/FXO
ports and the corresponding PBX port.
