Question: Hi, are there any quality certification for this product?
Answer: Thank you for your inquiry. It appears as the manufacturer has only listed RoHS as a quality certification. If you would like a recommendation based on Certification needs, please feel free to contact your KVM Switches Online sales representative.

Question: Hi there, I am looking to buy the CS1742 and have a dual monitor and 2 computer setup, the only issue I have is that the 2 computer only have 1 VGA port each, but the instructions appear to show that 2 VGA ports per computer are needed (can I use VGA to HDI concerter instead?) many thanks, Rob
Answer: Thank you for your inquiry. Unfortunately, this device requires two analog video signals for dual monitor functionality.

The tricky bit will be sending an analog signal via the HDMI connection. If it is a digital signal, the KVM will not recognize it, and an active conversion device, from digital to analog, can be expensive and may not produce desirable results.

When dealing with KVMs, we always recommend using the native signals required by the unit for best performance.

Question: This product only appears to include the switch and no cords? Is this correct? And I assume a power cord is provided?
Answer: Thank you for your inquiry,

The CS1742 does include the KVM cords along with the switch:

Aten CS1742 - What's Included?
(1) 2-Port USB Dual-View KVMP Switch
2x KVM Cable (VGA, USB; 1.8m/6ft)
2x KVM Cable (VGA, Audio; 1.8m/6ft)
1x Firmware Upgrade Cable
1x User Instructions

As far as the power cord goes, the use of a power adapter with the CS1742 is optional, for example if the unit is not receiving enough power, and requires a separate purchase - a DC5V 2.6A Power Adapter with the inside positive and the outside negative.
