Overview
The ATEN ProXime CE790 is an IP based KVM Extender with automatic cable detection (Auto MDIX) and RS-232 serial functionality that allows access to a computer system from a remote USB console (USB keyboard, monitor, and USB mouse) anywhere on the intranet.
The CE790 system consists of a transmitter (CE790T) that connects to the computer system and a receiver (CE790R) that is located on the user's desk. Because it allows access to the computer system from the remote console via a standard TCP/IP network, the CE790 is perfect for use in any type of installation where you need to place the console where it is conveniently accessible, but you want the system equipment to reside in a safe location – away from the dust and dirt of the factory floor, or the harsh environmental influence of a construction site, for example.
The CE790 is also useful for control and security purposes, where you can have the system unit in a secure area at the same time that you put the console in the most convenient location for user access. This is ideal for managing highly confidential data systems.
The CE790 improves on previous designs by: 1) the addition of an intuitive On Screen Display (OSD) on both the transmitter and receiver units for easy setup and operation; 2) working over a standard TCP/IP LAN network via inexpensive Cat 5e cable that allows point-to-point, point-to-multipoint, and multipoint-to-multipoint administration without the need for an additional KVM switch; 3) the addition of an RS-232 port, on both the transmitter and receiver Units to connect to a serial terminal for configuration and serial devices such as touchscreens and barcode scanners; 4) the addition of a dedicated KVM port section on the Local Unit so you can simply and easily include a KVM switch in your installation; and 5) featuring a custom ASIC to ensure the utmost in reliability and compatibility.
With an OSD, RS-232 support, and Auto MDIX, the CE790 is the most cost-effective and convenient way to get a full workstation experience from anywhere on the intranet.
