Powering MGS1600 v3.1 using Pins 5 & 14 on RS232

4 years 9 months ago #29531765 by jjamal
As a test, I tried to connect the MGS1600 using USB and it worked fine. The MagSensor Control Utility is reading data as it should. Now, I need to power it using only RS232 pins. I tried to connect it a 9V battey by connecting the positive to pin 14 and negative to pin 5. I also connected the wire braid to the negative. Shouldn't the power light on the sensor turn on? These are the only two pins I have connected so far.
Thanks

Hello,

yes the LED should be on, make sure your connections are correct. Make sure the power down cable is floating.

Niko,
Thanks for the your comment.
I left the power down floating; I connected it to 9V along with the Power IN; I connected it 9V separately; I disconnected the braid Ground; I connected it to along with black Ground to negative terminal of battery; still no success.

I am not sure if it applies here, but I stumbled upon an older version of MGS1600 datasheet. Its Version 1.1, July 30, 2012; and I see on page 4 that, there is a "Power Source Select" feature. It says, "The power source selection is done using a jumper on the 6-pin header (see Figure 2)". Does this still apply on newer versions of the sensor. If that is the case, then I will have to pop open the sensor casing and it looks like the two pieces of casing are glued together.

Thanks

Hello,

This datasheet is obsolete. Since your MGS is v3.1 you should follow the respective datasheet.

We have not faced that issue before and it is a rather simple case, in order to think what could be wrong.

Please send me photos of the MGS labels and the connections you have made.

As you can see in the photos,
I have Yellow+black and red wire connected to positive terminal of the battery. And Braid and Black connected to the negative terminal of the 9V battey.








The Power LED does not turn on.
Thanks

Hello,

the connections look good. Check with a voltmeter between Vin and ground how many volts are measured and if there is volt drop. If this is good then please report the issue to customer service department (This email address is being protected from spambots.

I measure a 0.5V drop when I connect a voltmeter in series. Does that mean that the sensor is working but only the light is broken?

In you first post you mentioned that with USB the magsensor is functional. If the LED was on then it should be on with battery as well. We cannot tell what could be wrong. You are the first to report such an issue.

It seemed like a hardware issue. I received a replacement sensor and its working. Thank you.
