Pressurized Module to Truss Connector

Termed the Z1 Truss this connects the pressurized modules to the Space Station truss.  It will be fastened to a port on a US Node or Module, making it very secure. The connector also houses a Ku-band transmitter (the Ku-band is a high quality channel used by television stations and international communications satellites amongst others). It also has a device to replenish the ammonia in the cooling system.
