The XBee RS-232 PH Adapter provides short range wireless connectivity to any RS-232 serial device, with available solutions for both mesh (including ZigBee) and point-to-multipoint networks.
Unlike an embedded wireless module, which requires design integration and development time, these off-the-shelf adapters provide instant wireless connectivity to existing RS-232 serial devices. All XBee adapters can be used with Digi's ConnectPort X gateways for data aggregation and IP connectivity
Using a powering mode known as power harvesting (PH), this adapter is powered by the connected host device through its RS-232 serial port. Power requirements This product requires a fully functional serial port conforming to the RS-232C standard for optimal operation.
The RS232 connector is an industry-standard DB9 male connector with a DTE configuration, similar to a PC serial port.
It requires a sleep/wake duty cycle as part of its normal operation. An internal battery provides power when the adapter is operating, and recharges from the serial port when in sleep mode. The sleep/wake duty cycle requirements vary based on the current output of serial port. Serial ports that provide hard power of 5 to 14VDC on one or more pins allow the device to operate continually without a sleep/wake cycle.
WARNING: Do not use this adapter with serial ports with more than 14VDC output as they may cause the adapter to malfunction.
Data retrieval
Retrieving data from XBee adapters is done by issuing a remote AT IS
(Force Sample) command through the XBee API.
