Introduction
Overview
The CE750 is a USB (Universal Serial Bus) based KVM Extender with automatic signal compensation and RS-232 serial functionality that allows access to a computer system from a remote USB console (USB keyboard, monitor, and USB mouse).
Because it allows access to a computer system from a remote console, the
CE750 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 CE750 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 CE750 improves on previous designs by: 1) the addition of an RS-232 port, on both the Local and Remote Units – the RS-232 port on the Local Unit allows you to connect to a serial terminal for configuration, while the RS-232 port on the Remote Unit allows you to connect serial devices such as touchscreens and barcode scanners; 2) 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; 3) using inexpensive Cat 5e cable instead of bulkier, more expensive, standard cables, for a much neater, more convenient, more reliable data transfer connection; 4) its ability to sense the distance to the system and automatically adjust the gain accordingly; and 5) featuring a custom ASIC to ensure the utmost in reliability and compatibility.
Further CE750 key features are built-in 8KV/15KV ESD protection and 2KV surge protection, and picture compensation pushbuttons on the Remote Unit to adjust the picture on the remote console.
Setup is as easy as can be – simply connect the computer system box and local console to the Local CE750L Unit; run the Cat 5e cable to the Remote CE750R
Unit (up to 150 meters away); and plug the remote console into the Remote
Module.
