Power, Indicator Lights and Standards Compliance for the magicJack plus 2014
In this video I quickly go over the power, indicator lights and the contravention of phone line polarity standards for the magicJack 2014 in comparison with the magicJack 2012.
Today we’re looking at indicator lights, power and some standards for the magicJack plus. We’ll be comparing the magicJack plus 2014 to its predecessor, the magicJack plus 2012.
For starters, when I plug the 2014 into the killawatt ez, it shows me
that the device draws about one tenth of an amp continuous. When I plug
the 2012 into the killawatt ez, the older device draws about the same
number of amps.
I looked at voltage. When I measure directly from the 2014 power
supply, I get a measurement of about 5.23 dv volts availble to the
magicJack. When I measure the two USB ports on the magicJack itself, the
voltage is just at about 5 volts. For the 2012, the volts measure just
over five volts at 5.04.
I then used my Gardner Bender line tester to check the polarity of
the phone jack. Ideally, the polarity tester should give a green light.
The magicJack 2014 does not pass the polarity test and instead gives a
red light. The magicJack 2012 does pass, as seen with this green light.
Next, lets look at the indicator lights. When we first plug in the
2014, we get a continuous blue light, followed by a continuous green
light for about ten seconds. Then the green light blinks on and off in a
two second cycle. About five seconds after you plug in the ethernet
cable the red light will glow for a few seconds and then blink in a
similar two-second cycle. When you plug in the phone jack, indicator
lights don’t change in any noticeable way. When your device is working
correctly, you should see a continuous blue light with the red and green
lights chasing on and off as shown here. The blinking green light
suggests the device has passed internal diagostics and is ready for use.
The blinking red light suggests your device is properly connected to
magicJack’s proprietary SIP servers.
The 2012 has a single plus-shaped light port. When first powered up,
the blue light remains continuous. In about five seconds a white light
slightly below the blue light will begin blinking in a two second cycle.
Nothing changes on the 2012 when you connect to the ethernet cable, and
the same is true with the phone cable. When you see a continuous blue
light with a white light blinking from within the same light port, the
magicJack 2012 is functioning correctly.
While most modern phones have built-in diode bridges to prevent
problems with line polarity, the magicJack 2014 does not pass the
accepted polarity standard that has been part of phone services for
almost as long as phones have been in business. I doubt this was
intentional because anyone who might use the device for non-magicJack
purposes on a system that needs the accepted polarity standards would
merely need create a cheap polarity reversal cable between the phone and
the device, circumventing the design flaw. I can only assume the flaw
is unintentional. Please post your thoughts in the comments. Was it
intentional or is there some proprietary reason why them might have
flouted one hundred thirty-some-odd years of polarity standard?
We still have yet to see how the USB ports and the SDIO port will be
used. Previous chats with magicJack chat support suggest a future
firmware update will give the device access to these ports. With regards
to WiFi, it’s possible the device could use an off-the-shelf SDIO card
like one from SpecTec. Unfortunately they currently offer only a mini SDIO card. There are no micro SDIO cards available in the marketplace as of this posting, but who knows, a device that fits may be just around the corner.
The USB ports may be for use with USB phones. I’ve tried two old USB
phones that work with skype, msn and yahoo messenger and many SIP soft
phone apps, but the magicJack plus 2014 currently does not recognize any
of these. Let me know if you find one that works with yours.
In a previous post on the mjcheck website, I showed how the magicJack
plus 2014 costs about 61 cents more per year to run than the magicJack
2014. Perhaps this is because more power may be needed to run
peripherals from the magicJack.
That’s all that can be said of the magicJack 2014 in comparison to
the 2012 with regards to power, standards and indicator lights.
Hi,
ReplyDeleteI have the MagicJack plus and it is working just fine. Why should I care about the polarity issue that you describe?
