TVP-221H User’s Guide

The first time you connect to the TVP-221H for configuration, you will need to connect to it under the same LAN segment to set the DHCP or PPPoE client. To configure the TVP-221H, insert one end of an Ethernet cable into the RJ45 WAN port on the rear panel of the TVP-221H and the other end directly to your PC Terminal. Open your browser and enter the TVP-221H’s default IP Address: 192.160.0.1. Make sure your computer’s Fixed IP is in the same segment. (See Chapter 4, PC Configuration). The TVP-221H supports auto MDIX so you do not have to worry about the cable. Any Cat 3 or 5 cable will be sufficient.
