Reverse KVM problems

I have a Belkin OmniView 2-port Reverse KVM Switch. This has worked fine for 18 months until I have re arranged the position of computers, UPS, wire less video camera and monitors. The left monitor flikers off and on and sometimes stays off for long periods. Probem is always the left monitor even if cabling and monitors are swapped around from the kvm switch outputs. Sometimes switching on an appliance with a low power motor will cause the screen to fail even though the motor is five feet from the monitor. I have tried re arranging the monitor cables to keep them away from other equipment. Swithching off and disconnecting the video camera makes no difference, I still have a blank screen, but sometimes switching the video camera on causes the problem. I think this may be a shielding problem.

Re: Reverse KVM problems

Problem sorted. Signal would always be lost in shortest cable. Used 2 cables of identical length.

Re: Reverse KVM problems

If you are sure the left monitor?s power is not the source of the problem it does sound like a shielding or excessive signal loss in a device/cable. If it?s always the left monitor I would try unplugging the video cable that goes from the left monitor and plug it into the right monitor; do the same with the other monitor. If the problem moves to the right monitor then that eliminates the monitors and we move on. If the problem goes away then probably one monitor had more signal degradation than the other. If the problem stays then the monitor is the source of the problem. If the problem followed the cable then I would exchange the cables that run from the switch to the monitors; if nothing changes exchange the cables that run from the switch to the PCs. If exchanging any of these cables results in the problem moving then you have a damaged cable or a bad connection. If the problem is still on the left monitor unplug the cables from the left PC that run from it to the switch and plug them into the right PC; do the same to the right PC. If the problem moves then you might have a damaged switch OR perhaps the video card output on one of the PCs is weaker than the other. All cables and devices weaken the video signal to some degree but the amounts can differ wildly. Over the years I?ve had this problem caused by cables, switchboxes, video cards, radio transmitters, bent connector pins, poor connections, excessive cable lengths, monitors and accumulative signal loss from several devices. The last is the hardest to diagnose. Good luck and let us know what happens.

Problem with serial connection with AMD motherboard

Software that accesses serial ports usually allow you to specify WHICH port you want to connect via.

Your new board should have COM1 and possibly COM2... but perhaps your old setup was running from COM3?

Connect the Casio to COM1, and check the software you are using... set that to "look" at COM1 also. That should work!

How to use cross cable and straight cables in network

ok, i think what you mean is this.  Crossover cable is for connecting 2 computers together without the need for a router.  also called pc-to-pc.  Straight cables need the use of a router or hub to connect 2 computers together.  Hope this helps, if not let me know more info.

Video splitters

I don\'t know about your specific brand, but splitters have losses that are typically 3.5,6, 7.5 and 11 for 2,3,4 and 8 way.

In most cable modem applications, we use a single 2-way so that the cable modem has only a minimum loss, then the TV\'s get put on the other side of the 2-way and split as many times as needed.

Here\'s a link to a typical splitter manufacturer where you can see the printed insertion loss of the various splitters.

Belkin N Wireless Router doesn't connect to Modem

If router is brand new you should have a set up disk. the set up disk will walk you through it or you might log onto Belkin site to see a walk through set up. If you can access internet from modem to router to internet. That means router is functioning properly. To go completely wireless you will need to secure your network and setup your access codes. Definitely use the setup disk to do this. A unsecured wireless network is a nightmare waiting to happen. Good luck
