The ACU2028A ServSwitch KVM (VGA/PS/2/Audio/Serial) over CATx Dual-Access Extender Kit by Black Box, comprised of a local transmitter unit and a remote receiver unit, enables you to access your PS/2 CPU from either a local or a remote PS/2 keyboard, VGA monitor, and PS/2 mouse. CATx cable (either CAT5, CAT5e, or CAT6) is used to extend the distance from your PC up to 984.3'. Serial control and bidirectional stereo audio ports on each unit allow you to connect serial and audio devices at both workstations. This extender features skew compensation and supports video resolutions of up to 1600 x 1200 at 656.2' and 1280 x 1024 at 984.3'.
The local unit is connected directly to a PC's CPU using the included extension cable, and the remote KVM console is attached to the remote unit. On the local end you can attach a local KVM console which will contend with the remote station for CPU control. Every time the inactivity timeout period elapses, the dual-user extender switches automatically to the first station from which it detects a keyboard or mouse activity.
The serial and bidirectional stereo audio extensions enable you to attach a serial control port device and audio devices to the remote station. Bidirectional stereo audio and full duplex serial data can be sent along with the KVM signals across the twisted-pair cable. For the serial interface, no setup or adjustments are required. The audio interface is designed to receive the output from a sound card (or other line-level) source and be connected to a set of powered speakers at the remote location. Stereo audio can be transmitted either way across the extender link. A microphone source input can be plugged into the remote unit.
The remote unit's deskewing technology removes color drift by delaying some color signals to compensate for differences in wire pairs. Skew compensation works with all colors transmitted, resulting in a maximum compensation of 42ns, which is sufficient for most applications. Independent low-frequency and high-frequency equalization adjustment enables you to fine-tune the video to match your cable type. Video tuning and configuration can be done by entering simple commands on the keyboard attached to the remote unit. Preset modes help you find the right image balance, and the "quick skew" feature facilitates fast video tuning. All settings can be stored in EEPROM memory.
Because the extender performs complete PS/2 keyboard and mouse emulation, you can boot the PC without having a keyboard or mouse attached to it. The extender is 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. The extender requires no software. The remote unit draws its power from the included external supply, and the local unit is powered by the connection from the CPU's keyboard port.
