Hardware & Devices

Thanks for the hint.

Actually, I was looking for a piece of Hardware that can be used by users of my Software, who have NO Internet Connection at all. Strict Accuracy is far less important than the ability to provide a single timesource for the local network, which can be made tamper resistant by physically locking it in a cupboard in say, the managers office.

If you have a server on the LAN you should be able to use that. I'm not sure of the technical details of how to do it but I'm sure a Google search would come up with something.

Hi,

You Don't seem to understand what I'm trying to achieve.

I am accutely aware that the server on the LAN can provide a Time Service. I also know How to use that service.

This is a Hardware Forum, So I am looking for links for a piece of Hardware, Probably the size of a packet of Cigarettes, NOT FOR ANOTHER COMPUTER!

I am looking, for my own specific reasons, for an Independent Hardware Timing Device, which can be read by software, but which CANNOT BE Set by Software interfacing with it.

I've never heard of one, nor can I really find annything like what you're looking for. Most LAN I've been on use a time reference external to the network to it can't be tampered with and setup appropriate permissions on the domain so no user can manipulate the system clocks. All time is sync'd up to the reference server which is the only device that can get the time from the external source.

You want a time reference that nobody can mess with.

Actually it's a Hardware & Devices forum. Any system that acts as a time server is, ultimately, a hardware device, even if it uses software to interface with.

Schweitzer Electric Laboratories (www.selinc.com) makes a device that provides GPS time codes in IRIG format for just this purpose. Their market is the power industry, keeping devices in remote substations synchronized, but there's no reason that other industries can't use their stuff.

Thanks for the Reply.

This does not realy answer my question. For Starters, there is no specific requirement of accuracy, other than One day per Anum. What I'm realy looking for is a piece of hardware with the following spec:-

- The Time settings should NOT be able to be changed, other
than by keypad.
- Ability to run Entirely independent of any form of External Dataprovider.
- No Larger than say 200x100x50 Deep.
- Simple 16 key Numeric Keypad to set the time.
- Wired Network Connector to facilitate Software Time Queeries.
- Battery Backup, to maintain the time upon Mains powerfailure.
- Inability to be 'Set' through any Networking Port.

I am sort of amazed that a thing like this does not seem to exist.

Hi,

Thanks,

Found an Intermediate Solution.
-Bougtht a Very Very old PC with XP on it for £10.00 in a Car Boot Sale.(original Hardware Spec: Win95)
- Got Dumy Terminals so that it can fireup without keyboard or Monitor.
-Modified module config files so as to look for that computer for timestamps.
-Wiped Most of the User Programs, like MS Office, etc.
- Locked the thing in a Cabinet at the Users premises.

Works a dream! I had hoped however, that there would be an ethernet device or USB Device which would do this more elegantly.

Regards,

Which one could be the best buy?

You don't! Please at least learn the basics of the subject before asking questions. You obviously have no idea what CSMA/CD is.

I'm planning to buy a laptop. As I haven't owned a laptop before, would like to know the best laptop to buy with following criteria's in mind:

1. Main target is to do programming with Microsoft Technologies (VS2008/21010, SQL Server etc..)
2. Less than or equal $670
3. Better performance
4. Flexible to upgrade
6. Doesn't matter on Size and weight ( Smile | :)

i am healthy enough to carry)
7. Doesn't matter on maintainence and support (As i am buying from US, but not belong to US)

So you need lots of memory and a seriously fast HD, preferably solid state.

Ok forget the harddrive, and add the memory yourself after buying it.

See number 1.

Are you sure you want a laptop?

I've heard that one before, heavy laptops tend to be stationary, really, they do!

If you're buying a brand laptop you'll get the support worldwide whether you want it or not.

Take a look here[^]. It's a UK based site but some of the information is likely to cover PCs that are available worldwide.

No one has ever been sacked for buying IBM, or so they say.
Our Organisation owns 13 Laptops. 3 of those are Second Hand IBM's. When it comes to Support and Standard of Mechanical design, IBM wins Everytime.

IBM sold their PC business some years ago, I think to Aptiva.

Google for online discount codes. I saved 20%+ on my Lenovo laptop doing that 2 years ago. As long as you don't care about "voiding the warranty", you should upgrade memory and the hard drive yourself. Many manufacturers charge 100+% of the new part price to upgrade a component that might be a 10 minute install.

I lost track of the original driver discs for my machine. After I reloaded XP I only have USB 1.1. When went to Microsoft update site to update it to USB 2.0 (successfully). The Microsoft site did this by scanning my system and did the update automatically. There seems to have no way for me to install that driver manually.

I want to archive the USB 2.0 driver for XP on my machine, say save it to a CD. However, I don't know how I can download it from Microsoft site. Any ideas?

Thanks!

USB2 drivers are included with WinXP Sp2. So there are basically no manufacturer that bothers with making special drivers for USB2.

What I don't understand is I reinstalled XP, then put SP2 and SP3 on it. Both SP2 and SP3 were downloaded from microsoft.com. After that when I plugged a flash drive to the USB port I got the message:

This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port. For a list of available ports, click here.

This message appeared in a ballon box popped up from the system tray area.

After I put the update from Microsoft on, the message no longer appears. Why the SP2 that I installed does not contain the USB 2.0 driver?

Just a hunch: maybe the updater told you you had to reboot the system and you didn't?

You don't need to install SP2 if you're going to install SP3. Microsoft servicepacks are incremental.
Other than that I really don't have an answer. Sorry.
