Lightning Serial Cable (L2-DB9V)

Connects a Lightning iPhone, iPad or iPod touch to RS-232 serial devices at baud rates up to 115.2 Kbps.

This cable is used in conjunction with the Rsc Mgr SDK to create iOS apps that communicate with a serial device. It is licensed under the Made for iPod (MFI) program for private deployments under the terms of an enterprise, education and personal iOS developer license.

Under current Apple policy this cable may not be used with apps sold on the App Store.

LIGHTNING SERIAL PRODUCT FAQ

Q: What are the differences between the three versions of the Redpark Serial Cable?
A: The L2-DB9V uses the USB pins to communicate with an iOS device via Lightning connector. It supports a maximum data rate of 115.2 kbps. It requires iOS 6.0 or later.

The C2-DB9V uses the USB pins to communicate with an iOS device via a 30-pin connector. It supports a maximum data rate of 115.2 kbps. It requires iOS 6.0 or later.

The C2-DB9 uses the UART pins to communicate with an iOS device via the 30 pin connector. It may be configured to use a baud rate up to 57.6 kbps (although we have observed that the maximum sustained throughput is 40-45 kbps). It requires iOS 4.3.1 or later.

Q: What kinds of devices have serial ports these days?
A: Ham radios, dive computers, point of sale devices, Arduino and other micro-controller platforms, 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, model cars (models boats, planes and rockets too), CNC machines and more…

Q: What version of iOS is required?
A: iOS 6.0.x or later.

Q: Is there a way to connect to 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: Can I power the iOS device using this cable?
A: No. Please use our Serial+Power Cable instead.

Q: Can I power the serial device using this cable?
A: Power is not supplied through an 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 L2-DB9V 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 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 Cable in the “Settings” App, select the Serial Cable to view its parameters.

Q: What are the pinouts of the DB-9 connector?
A: This is provided in the SDK User Guide.
