The XO Computer for Navigation

[Jim St.Pierre]

Hi again Paul, I am a bit confused, hahahahaha you mentioned the "Alfa 500mW USB wireless-G Wifi adapter" also the "Engenius 2408 omni antenna" are these both antennas??? do I need both of them.??? Also, what if the computer has built in wifi, do I or can I disable it, or do I need to... Sorry for these questions but I really have no idea and need a pros help, such as your experence in this matter.....Thanks again..

Jim St.Pierre,

The "Alfa 500mW is a little USB adapter that plugs into a USB port and gives you wireless. You can use it on its own with the antenna that comes with ii but works so much better with the large Engenius 2408 omni antenna. You also will need the connector cable between the two which they refer to in the other thread as a pigtail. Here it is:

CompuNation - External Product Link: STARTECH, NRPSMA1MM

And beacuse this cable is so short, it really helps to have an USB extension cable of about 10 feet so you can mount the antenna as high as possible. I got the Enfenius, the pigtail and the usb extension cable at :

Shark Systems - Computer Hardware and Electronics Superstore

At I got the Alpha 500 on ebAY.

I you have an internal Wifi you can run it at the same time as the Alpha but I usually switch it off. You just have to select which wifi you are using if you have both.

Well I hate to say this but I've gone back to the dark side....

I happened to aquire an Acer Aspire 8.9" Intel Atom N270 Netbook computer running XP home edition. After I checked it out, I think its a much better computer than the XO at least as far as running the applications that I have like SeaClear and openCPN. It has 1Gig memory plus a 160Gig hard drive. It cost $250 from FutureShop. The screen is very readble and it has really nice keyboard. It has 3 USB ports and VGA output so I can connect it to the TV to watch movies.

So I replaced my XO at the navigation station with the Acer. I'm going to keep the XO at the helm because I think its a much more rugged than the Acer and better sunlight viewable.

How is its power consumption compared to the XO?

I'm mildly disgusted phiggins! Linux is always an option though..

idpnd, I know its terrible, I feel so bad, but its really better. I knew I'd disgust a lot of linux lovers.

Maren, That's something I've been trying to find out. When I try to measure the current its using connected to an inverter its always zero as I guess its running off its battery. I could wait until it charges the battery but that wouldn't be a fair measurement of what it uses normally. I looked at its documentation but it doesn't specify how much it uses.

Well in one week I'm sailing south with the XO at the helm and the Acer at the nav so when this trip is over I'll let you know more on which is better...God willing..

Cheers,

Hi,

I have posted this as a separate thread, but the message clearly relates to our discussion here:

".....

Samsung has announced they will make and sell laptops with OLED sceens within a year. According to the release: "...OLED has several advantages over conventional LCD screens, including higher brightness and contrast, better color representation and lower power consumption..."

Following LG's decision to deliver 15 inch OLED screens later this year we might hope the new technology will be promptly adopted into many boat's nav and entertainment systems.

Samsung says OLED notebooks due in one year | Electronista

Cheers,

Hello Paul, Update here on the computer and wifi. I have received the Omni 5 mile antenna, I have tracked my computer (UPS) should be here 09/11/09. I can't wait to get it on board and try it out. I wll keep everyone informed of my progress/sucess.... Thanks for all you help... Jim

I just took my boat out and anchored about 1 mile away from the wifi at the marina and the antenna worked great. Even the Magic Jack worked and I made a telephone call on it.
