The Rose CrystalView CRK-M2U1V/AUD is a mini USB dual local, single video with serial & audio KVM extender kit.  This system consists of two units, a Local Unit and a Remote unit. The Local unit connects to your CPU using a CPU adapter cable or a KVM switch. The Remote Unit connects directly to the keyboard, video monitor and mouse cables of a KVM station. The Local and Remote Units are connected together with up to 150 feet of industry standard CATx cable.  The CRK-M2U1V/AUD CrystalView Mini uses a microprocessor to emulate the keyboard and mouse for plug and play operation.  The keyboard and mouse on the Remote Unit do not need to be connected for the PC to boot; only the Local Unit must be connected to the PC. 

The CRK-M2U1V/AUD serial/audio model allows stereo audio to be transmitted in either direction across the CATx link simultaneously.  Many serial devices like a Touchscreen can plug directly into the serial port on the Remote Unit The Mini model is small in size but loaded with state of the art technology. It is ideal for extending the distance between a CPU and a KVM station up to 150 feet.

Question: Does it require any type of programming?
Answer: Thank you for your inquiry,

For setting up the the Rose CRK-M2U1V/AUD extender, depending on the CATx cable distance (15-75 ft vs 75-150 ft), you may need to flip the "Dip" switches located on the bottom of the Remote unit. This helps the unit balance the analog video channels to ensure good video quality at different distances. For more information on setting up the CRK-M2U1V/AUD, including the DIP switches, please refer to the Rose CRK-M2U1V/AUD Manual. Besides the initial setup, for standard point-to-point extension operation, the Rose CRK-M2U1V/AUD would not require any type of programming.
