The Serial+Power Cable includes an external 5v power adapter.
This cable is used in conjunction with the RscMgr SDK to create iOS apps that communicate with a serial device. It is licensed through the Made for iPod (MFI) program for use in private deployments under the terms of an enterprise, education or personal iOS developers license. Under current Apple policy this cable may not be used with apps sold on the App Store.

LIGHTNING SERIAL+POWER PRODUCT FAQ
Q: What kinds of devices have serial ports these days?
A: Point of sale devices, scientific instrumentation, data loggers, RFID readers, automobile engines, routers and other networking devices, glucose meters, fire alarm panels, irrigation controllers, weather stations, specialty printers, scales, temperature sensors, flight loggers, satellite radios, ham radios, model cars (models boats, planes and rockets too), CNC machines and more…
Q: What version of iOS is required?
A: iOS 7.0.x or later.
Q: Is there a way to connect to serial devices using TTL (logc level)?
A: Yes, by connecting an external RS-232 to TTL adapter to the DB-9 connector on our cable.
Q: What is the maximum baud rate supported by this cable?
A: 460,000 Kbps
Q: What are the specifications of the power adapter provided with this cable?
A: The power adapter that is provided with the Serial+Power Cable is a 5V 15W power supply. Many factors including ripple and noise, switching frequency and efficiency were critical to the selection of this power supply. (You should not assume that any 5V power source is acceptable.)
Q: Can the power adapter be used in markets outside of the United States?
A: Yes, the power adapter is a switching power adapter (100-240v). In the United States the Serial+Power Cable is shipped with a USA style power cord. Our reseller partners in other markets (i.e. Europe, Japan, Australia / New Zealand) offer power cords that are appropriate for their local markets.
Q: Can I provide power to the serial device using this cable?
A: Power is not supplied through the RS232 connection. Some very low power devices make use of the RS232 signal lines to supply power. This usage of the RS232 connection is outside of the RS232 specification and may not work in every instance. It is left up to the user to determine if the RS232 output signals will supply enough power for a particular application. Currently, the L4-DB9PV uses a MAX3243 or similar driver to convert logic level signals to RS232 level signals. The specifications for the MAX3243 may be used as a rough guide to determine if the signal levels are appropriate for your application. Redpark reserves the right to change the RS232 driver circuitry at any time.
Q: What apps does this cable work with?
A: The cable and SDK are provided to you so that you may write your own apps.
Q: Does the cable work with apps available at the App Store?
A: Not at this time. This will depend upon Apple policy.
Q: How can I tell if my iOS device recognizes the cable?
A: Open the “Settings” app on your iOS device. Select “General”, then “About”. If the Serial+Power Cable is connected properly, it will appear in the list shown.
Q: How do I know what version of firmware the cable is using?
A: Once you have located the Serial+Power Cable in the “Settings” App, select the Serial+Power Cable to view its parameters.
Q: What are the pinouts of the DB-9 connector?
A: This is provided in the SDK User Guide.
