SOURCE: 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.
Here is suggested scheme of original 940-0128A cable

df1c50d.png This is for a newbridge or alcatel 3624 mainstreet channelbank - do not use the modem side, only use the terminal side - all is needed is Rx, Tx, and ground - if looking from the "window" side of rj45 connector, or pins-side up on rj45 socket.

You need to have SATA drivers, before installing Windows XP. SATA drivers are not included in the CD, unlike Vista. There are many websites which explain how to include SATA drivers in your CD. You may have to find right SATA drivers depending on your laptop.

How to do lamp reset on panasonic pt-lb50u projector.


To reset the lamp hours, turn on the projector. Then press Menu and use the Up/Down arrows to highlight Options. Press Enter then highlight Lamp Runtime. Press and hold Enter for 3+ seconds until the Lamp Runtime screen is displays. Press the Power button (any other button cancels the reset). When the Power button LED turns red, unplug the power cord to the projector. You can either use the remote or the controls on the projector. Reconnect the power cord after a few minutes.

The reset instructions are on page 62 of the user manual. The manual is available from Panasonic here: https://support.panasonic.co.nz/docstore/PT-LB50U%20Operating%20Instructions.pdf .

I hope this helps.

Network adapter not found when running wireless program


Sounds like the Apple Dealer is onto the right idea.Unfortunately wireless control for projectors is still in it's infantcy and subject to compatability issues. A complicated alternative is to "Try" a wirless bridge adaptor in between the laptop and the projector. using the lan port on the projector, you would set up a mini lan between the projector and the bridge, and you would get a wireless connection between the mac and the bridge.
Probably too complicated, the extra cable may just be the go for now until panasonic release the firmware upgrade for you.
Good Luck in the Courtroom!

Problems with Projector Panasonic PT-L501XU after change the lamp


was this bought new or second hand?
There is a "Lamp Time" setting that can be accessd using your remote control, check this setting.
Look on page 40 and after that of your manual about ambient temperature bulb failure.

By powering off or hittign the reset button the bulb should stay on IF the projector is gettign a signal from a device to show an image. If the projector is not hooked up to a device, laptop, TV, etc. the bulb may turn off to save hours of operation.
