We too use the black box kvm's with very good results. We have had some running for 7-8 years w/no problems (ps2 type) and last year added the usb type. There were a couple premature failures on the USB (within 1 month) but generally work well. Our longest distance is about 50-60 feet. I wanted to respond to this because of a unique gotcha that I ran into yesterday. I had a station having problems with USB mouse/kbd so I rebooted the KVM's and the workstation. It seems that the P92 don't identify the keyboard on the remote USB-KVM until after bios finishes. We get a kbd not found until after bios is finished. When it rebooted I had a "Temperature sensor failure" warning during the hardware initialization with a "press F1 to continue and F2 for setup". Since the P92 won't identify the KBD until after bios is up I was stuck. The work around was to put another KBD in a local USB port and hit the F1 and then remove it again. The basic functionality of the extenders works great and very little problems. For KVM "AND" annunciator kbd cabling we used Siemens industrial Cat6 which is easy to install. The Annunciator KBD also used the 8 wires as I mangled an old cable and figured out how to wire it thru CAT6 cable as rs-432(or whatever it is) along with some db9 to rj45 connectors. It has been working for about a year with little to no problems. Black Box is a very reliable solution and they are Foxboro supported. Now I have to figure out what this temperature sensor is all about in a P92. (can someone say field service?lol) Ronald G.
