Use in applications in which you need to hear audio alerts on remote monitors and need to connect serial devices, such as touch screens. The extender comes in a kit that includes local and remote units, which are connected with a single CAT5 or higher cable. All keyboard, mouse, and video signals as well as serial and audio signals, are fully buffered to ensure consistent remote operation of your PC.

With this Dual-Access model, you can attach an additional monitor, keyboard, and mouse to the local unit. You can then operate the PC from either the local or remote user station. These stations share access on a "first come, first served" basis.

Ultimate video at the remote end.
No matter what CAT5 or higher cable you use, you can expect clear, high resolution at the remote end with these KVM extenders. That's because the CATx kits' remote units and individual standalone remote units feature a built-in skew compensator. Color drift - caused by the different twist ratios of the twisted pair cable - is eliminated. The skew compensator removes the unsightly color shadows by delaying some color signals so that all color signals arrive at the same time at the remote end. This skew compensation works with all colors transmitted.

You can fine-tune the monitor image via simple keyboard hotkey commands to fix skew attenuation and losses. Use keyboard controls to equalize red, green, and blue to compensate for the differing pair lengths found in CAT5e and higher cables. Independent low-frequency (LF) and high-frequency (HF) equalization adjustment ensure optimum video tuning. The precise equalization enables resolution of 1280 x 1024 up to 984.2 feet (300 m) or 1600 x 1200 resolution up to 656.1 feet (200 m). Preset modes also help you find the right image balance quickly, and Quick Skew features help make video tuning nearly automatic.

ServSwitch Single-Video CATx KVM Extenders save all video settings in non-volatile memory.

Add standalone remote units to existing extender applications.
Do you already have a ServSwitch Extender at work for you? Want to add enhanced video capabilities? Just order a ServSwitch CATx KVM Extender Remote Unit (ACURA001A). These standalone remote units feature easy-to-adjust skew compensation and are compatible with many of our ServSwitch CAT5 Extenders. To determine which CATx KVM Extender Remote Unit will work with the extender you have, contact ServSwitch Central™ at 724-746-5500 or by clicking "Talk to a Tech."

Plug in your connections and go.
Setup is simple. Connect the local and remote units to each other, make any necessary serial and audio connections, and adjust your video compensation to your liking. The extenders are easy to operate and require no software.

Because the extenders perform complete PS/2 keyboard and mouse emulation, you can boot the PC without having a keyboard or mouse attached to it. What's more, the extenders are compatible with Microsoft® IntelliMouse® and other wheel mice. You can even use a standard PS/2 mouse at one user station and an IntelliMouse at the other.
