Does anyone have any details on the power supply for a Texas Instruments Silent 700 Model 703 Data Terminal? The "User's Manual" is no help and web-searching has drawn a blank. From the base of the unit I can see it is 20 volts 1.8 amps, but the connector on the back of the unit has three prongs, so I need to know what the power supply was delivering to each pin.

The Pin Assignment is as follows:
Pin 1,4: +5V
Pin 2,3: not connected
Shield: Ground
The AC Adaptor is specified as 5V , 4Ampere. Actually the unit draws around 2-3 Amperes.

This "Image" shows the pins, when you look onto the jack at the back side of the terminal, with the terminal standing upright. The label = 5V is located left of the jack

SOURCE: my protron lcd tv power supply died and i would

Mine did the same thing right before 4th of July. I was watching tv and it just went off. At first I thought my power had gone out, but the tv was the only thing that was off. I tried to turn it back on, but it was dead as a doornail. :-) When I plug in the power cord the blue light usually comes on or the fan runs, etc. I tried to plug in the power cord and it did nothing, so I was upset thinking I had to get another tv.

I took a gamble that it was the powercord and after searching and searching finally found this website. http://www.lcdpayless.com. I placed my order on Thursday and went out of town for the 4th and I checked my mail today (Monday) and it was there. I plugged it in, the power came on and the tv works perfectly....plus the new cord doesn't have an annoying fan.

The cord is pricey at $117, but it beats buying a new tv. The company accepts returns minus a 20% restocking fee and shipping, so I figured worse case scenario I would only be out of $40+bucks if it didn't work and I had to send it back. So, if you plug your current power cord in and it's not lighting up, it may be your power cord. Hope this helps!!!

SOURCE: how do I get 12 volts at the factory installed trailer connector

You are correct. There is a fuse in the underhood fuse/relay compartment that powers up the pin. It is one of the larger fuses and should be labeled as "AUX". Also check that the power wire is connected to the AUX bolt terminal. They shipped from the factory disconnected and the cable was zip-tied to something below the fuse box.

Testimonial: "I knew there had to be something needed done, I'll check in the morning under the fuse panel for a wire to terminate and see what happens. sounds log"

SOURCE: Need Behringer Eurorack mixer power supply connector

Those were used for mic connectors at one time,,, they are related to the Amp 91-MC3F family of connectors and those are out of production and they are demanding $20 to $50 for one connector.

That is a ridiculous price and I would be tempted to swap out the connector for a more available design.

On eBay item 250401122616 is one but they want $13 pus $11 shipping which is a rip off.

These were used on some OLD CD radio mics.
