Overview
The Versa RS-232 zigbee Adapter provides short range wireless connectivity to any RS-232 serial device, with available solutions for both point to point and point-to-multipoint networks. Unlike an embedded wireless Module, which requires design integration and development time, these Off-the-shelf adapters provides instant wireless connectivity to existing RS-232 serial devices. 
Power options
This product can be powered by a 5-12VDC external power supply or by the host terminal unit to which the module is connected. In this case the power is supplied through the 9 pin D connector. The module at the PC end will always require external power supply. In case of USB board, the power is derived from the PC. 
Connection and power-on
1. Connect the desired device (terminal unit) to the RS-232 port of the module. 2. Connect the power supply to the module.
