What you need to know about RS232 Serial Cables for Android
PRESS RELEASE - September 13, 2014 - For Immediate Release

Anyone who is looking for a serial cable solution for their Android smart phone or tablet will be wondering about the different options on the market. You may have even found a model, heavily advertised by the mainstream retail outlets, which is marketed as a micro USB to RS232 serial adapter cable for Android. However, it won't be until your money is spent and it turns up on your premises that you realize some problems. This heavily promoted cable does not have a power source and actually depends on the availability of an AC adapter! This requires a second wire to be added, and you end up carrying six feet of wire in your pocket. This is not a very mobile solution.

The Android RS232 serial cable PDCA-M9-6 from long ago overcame all of these problems. What you will get when you order from is exactly what you wanted, and nothing extraneous. Instead of six feet of wire, what you get is six inches - perfect if you need to carry it around. And now for the most ingenious part. The PDCA-M9-6 is powered directly from the Android! When you plug the cable in, the Android is smart enough to power the cable through the micro USB connector.

The PDCA-M9-6 cables works with Google Nexus 7, Samsung Galaxy Note 3, and in fact any Android which supports OTG host. This cable works properly with the Android in order to implement a true RS232 serial port on a 9 pin male Dsub connector with the same pinout as a PC serial port. This is the most common serial port pinout configuration, and most applications are able to use this exact connector. On the other hand, ECYPH LLC offers customization at any volume level so if you have a special application which has different connectorization, you need not worry. We are able to modify this cable to meet the specifics of your application.
