The Z-TV RS232 Centralized TV Control System features a fully functional IP to ZIP-232 Serial Controller, which is available in a 24-port configuration. The 1U high rack mounted serial controller utilizes RF-45 connectors and has one administrator assigned IP address per device. The serial controlled devices (TVs, Set-Top boxes, etc.) are accessed and controlled by the numbered output ports via the ZIP-232 baluns. An external web server allows IT/AV managers to remotely control every connected TV.
