NEW X10 PRO 2-way Appliance Module PAM21 AM14A

This listing is for a new-in-box X10 PAM21 2-way appliance module.  The 2-way communication capability is special in the X-10 family as most modules either receive only or transmit only.  The PAM21 supports the status command, which allows a controller (e.g. CM11A) to obtain state directly from the module.  This capability can be used to significantly improve reliability.

Note: The X10 PRO PAM21 is interchangeable with the X10 AM14A.
