This is outside the scope of an electrical engineering discussion at this point, assuming that there isn’t another problem with the control. Thanks to all for your insight. Will see what they have to say and report back Todd. We usually datashfet to the confirmed eBay registered shipping address. Please return products ASAP after we offered shipping label,Late shipment will effects the date when you get refund.

If so, then maybe the cross reference is accurate and your module also has an RTC in it. Please bid or “Buy it now” only if you agree the price and condition of the product and no argument after the auction ended. Sounds like you need to call Electro Mechanical Integrators. They pretty much can handle any Bridgeport CNC problems. Where did you find the battery for your machine. I cannot figure why a bad RTC time would factor into the inability to power up the drives.

And you didn’t have to change any of the BIOS settings?

M48T86PCI Datasheet, PDF – Alldatasheet

HWElecRepair liked this post. Any additional advise on any issues you ran into would be great also. Typed that number in a search on m4886pci Jameco website and it pulled up a DS From what has been said here it sounds like I am missing a parameter or two.


I had the technician look up the chip number also to make sure that was right. Results 1 to 20 of You’ll be replacing it anyhow!

Standard Shipping covers full tracking details,Economy Shipping usually doesn’t cover full tracking unless your order amount big. But, fundamentally the module doesn’t do anything but provide the time and date for the system. If you do not receive your item on time, please let us know earlier, we are always solving problem on the basis of mutual assistance to ensure your benefit. We accept Paypal only, it is fast, easy and safe. That module is nothing more than a real-time clock.

Yep, that is pretty clear! Shipping Policy Very Important: I don’t see why so many sites come up with that number having a cross to a DS If so, then there is a moderate chance you may be able to pull the plastic top off and replace the Lithium button yourself Whatever the case, it sounds like you are now in need of a tech that can tell you what buttons to press.

I had quickly perused the datasheet on the RTC but I didn’t see that it had user accessible memory In fact, I have one sitting in my garage, but it probably has a dead battery in it.

I posted over at cnc zone.

For buyer who is not satisfied with your purchase Please contact us before you leave feedback, we will fix the problem for sure! I understand how RTC chips work, and that they have memory in datasheeet, but if it isn’t user accessible then it is irrelevant.

Feedback will be left to all transaction automatically. I’d have guessed that they would have another SRAM that is battery backed up someplace on the board. We offer m48t8pci if there has problem with our products,such as bent leads,scratches all over surface in transit 4. We do not responsible for any custom datsheet or import tax.

The number on the battery is m48t86pci Thanks for any help you can give. Dagasheet I can find it at all, let alone a datasheet, it is usually from a dealer in China that specializes in obsolete parts It has a battery so that the counter can continue to do its stuff while the power is not connected. When the chip was replaced the technician put in a socket so I could swap catasheet however I wouldn’t be able to get as far along with the old chip to start the machine as I can with the new chip.

When I push the m8t86pci to do that I get the message ” drives not on, failed to go home” Any suggestions? So I got my friend the electrician that replaced the battery over to have a look. Hi Todd, Hmmm, something is fishy here The flip side is that I’ve usually been able to find a cross reference eventually.
