# Remote Ack Handshake connection

When the application starts, this connection has a value of one. When the Remote Ack connection value changes, the Remote Ack Handshake connection's value toggles from one to zero. The next time the Remote Ack value changes, the Remote Ack Handshake value toggles from zero to one.

The Remote Ack Handshake value toggles whether or not the new Remote Ack value matches a trigger value.
