The ACURA004A ServSwitch KVM (4 x VGA/PS/2/Audio/Serial) over 4 CATx Extender Remote Unit by Black Box is used in conjunction with a ServSwitch local hub unit to receive 4 video channels and PS/2 keyboard & mouse signals from a CPU located up to 985' away. Additionally, the receiver features daughterboards which allow bidirectional stereo audio and full-duplex serial data to be sent across the CATx interconnection cable along with the KVM signals. Up to four monitors can be connected to the remote unit. Four CATx (CAT5, CAT5e, or CAT6) twisted-pair cables are plugged into the unit on the front panel via four interconnect ports. The first port receives the primary video and data signals, and the other ports receive the additional video signals. All RJ-45 ports are surge protected. A built-in skew compensator helps to maximize video quality.

The ACURA004A receiver's audio interface is designed for receiving output from a sound card or other line-level source and to connect to a set of speakers at the other end of the link. Stereo audio may be transmitted either way across the link-simultaneously. You can also plug a microphone into the remote unit's "line in" connector and, if required, set its amplification to +17dB. For the serial interface, there's no setup or adjustments required. It transmits six signals (three in each direction). You can attach a serial touchscreen directly into the remote unit. To connect a serial printer or other DTE-wired device to the unit, add a null-modem crossover cable between the unit and the device. All KVM, serial, and audio signals are fully buffered on all channels to ensure consistent remote operation of your PC.

The receiver's skew-compensator 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 receiver. 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 receiver performs full PS/2 keyboard and mouse emulation, you can boot the PC without having a keyboard or mouse attached to the local unit. The receiver is compatible with Microsoft IntelliMouse and other wheel mice. The video capabilities of your ServSwitch extender hub can be enhanced with skew compensation by replacing its remote unit with an ACURA004A standalone-receiver. ServSwitch KVM extender hubs (with serial extension and bidirectional stereo audio) compatible with the ACURA004A include the ACU1006VRA and ACU1006ADVRA.
