Question about Raymarine SeaTalk hs, 20m (E55052)

Open Question

Fishfinder problems I have a Koden cvs-821 model fishfinder. It has started losing signal. Everytime we initially turn it on it works fine and gathers the signal. After a while, and usually when we are at sea, it appears to get depth confusion, puts up a question mark ?, and the screen stops movement. Any signal then disappears and the screen goes to its normal background blue. The sounder then is not able to recover the signal. Oddly enough whenever it has been off for any length of time, which is usually after we are home or the next day, it works fine again. We took it to a technician and he couldnt find anything wrong with it as it worked fine. Could it be a faulty transducer or it it likely to be in the in the sounder.

Two equipments of the same type - two computers, two routers, two switches - should be connected with a crossover cable.

I changed the NIC card in my HP pavilion and now my machine will not power up. It was working fine prior to this. Could I have blown a fuse or something? Any suggestions?


While there isn't a "fuse" to blow, there are several things that could prevent your system from booting after making hardware change. However, there is a distinct difference between not booting and not powering on, and for further troubleshooting we'd need to know which is the problem. In the mean time, here are some things to consider:
1. An incredibly small amount of static electricity can short your motherboard and prevent the system from booting at all. Whenever you do any time of hardware update or configuration change, always where an electrostatic discharge wristband to prevent damage to your system.
2. If you somehow unseated the processor from the motherboard during your upgrade, then the processor would lose some of its ability to dissipate heat, which would cause an automatic shutdown.
3. It is possible that you loosened a wire/jumper/plug that was integral to the boot system of your computer.

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!

Rj45 male to db9 male cable for ups


If you have a BackUPS CS, you are probably either using it with the USB cable that is supplied or with the 940-0128A supplied by APC, which permits running the UPS in dumb mode. By building your own cable, you can now run the BackUPS CS models (and perhaps also the ES models) using smart signalling and have all the same information that is available as running it in USB mode.
The jack in the UPS may be easily use a 8 pin RJ45 connector. It is easy to construct the cable by cutting off one end of a standard RJ45-8 ethernet cable and wiring the other end (three wires) into a standard DB9F female serial port connector.
PC Signal PC pin UPS Pin UPS signal RxD 2 2 TxD TxD 3 8 RxD GND 5 7 Ground FG Shield 4 Frame Ground Though these UPSes are USB UPSes, APC supplies a serial cable (typically with a green DB9 F connector) that has 940-0128A stamped into one side of the plastic serial port connector.

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.

Black-box regd


There are NO drivers needed or even provided by BlackBox for this device. It simply uses hardware circuits to convert an RS232 signal to a RS 422/485 signal. My first reaction to this question is: Do you have your PC serial port at 9600baud which is the default RS232 signalling rate for this device? (I guess I probably won't hear a response on this as the question is almost a year old, with no attempts by anyone to solve it. I'm the only glutton for punishment.)
