I have an RCA Modem with an AC power input. 4 pin Can you tell me what voltage the input is and what frequency?

    I do not have the power supply.
    I asked about frequency because the transformer connected to the power input looks like a high frequency transformer. I thought there might be a converter in the power supply.

It should be on the power adapter itself after output.
If your in the US it's 120V 60 Hz.
Why are you asking about frequency?

RCA dcm325 specs


The Installation and User's Manual [http://www.simplehelp.net/images/cable_modems/manuals/RCA_DCM325.pdf] says this modem can receive data at rates up to 30 MB/second in a DOCSIS-compliant cable network. It can connect directly to two computers simultaneously, one through the USB port and the other via Ethernet. The USB port software supports only Windows 98SE through XP, but may work with newer versions of Windows.

Operating temperature range is 0degreesC-30degrees C. For power input, the only thing I could find was a picture of the back showing "800 mA" under the AC adapter jack; the voltage input value is obscured by the plug in the picture. You should be able to read it on the modem itself, or the power adapter if you have the one supplied with the unit..

I accidentally knocked the AC adapter to my RCA DCM425 Cable Modem AC out of the wall outlet while at my computer desk. After plugging it back in, the lights on the modem flashed on momentarily, then shut...


You could have only a damaged power supply, please look in an Eectronics parts store another with the same characteristics (input and output voltage,current, plug type) and retest, maybe your actual AC adaptor is broken inside and that's why it doesn't power up your modem correctly.

Input voltage for Boca 56K tidalwave external modem


There should be a input voltage and polarity (pin) diagram next to the power input socket. Normally 12 volt, but don't quote me on that as I just replaced my modem, like for like and the old one was 12v. and the new one 25v. so if you can eliminate your power adapters one by one by the manufacturers names on each, then thats your best bet.

My tram 2512 is stuck in waiting for AC mode, ac is clearly reaching the unit, both by shore power and genset. What could the problem be?


If you are referring to a Trace 2412 inverter, which series is it? An SW or a DR series? In either case, if it won't accept generator power, but the AC input indicator is flashing, the problem is most likely the generator output power is off frequency or voltage. Trace inverters will only connect when the AC input is within certain limits. I'd suggest checking the frequency and voltage output of the generator. If it won't connect to shore power, check the voltage from that source. Make the voltage checks at the inverter input terminals.
