Radiometrix(RPM3-869-17)

Hi

Now i am working on the wireless communications, the module is 
RPM3-869-17.

Searching on the internet, the datasheet is RPM3-914-17, it is not the
RPM3-869-17.

This is mine first time in wireless, and this module.

So do i just need give the power, connect to the ground, and only use 
the TXD and RXD pin?

Thanks
