Description
The Telemetry Control Unit (TCU002) is the communications control center for the logging system. It provides communications on standard service mono-conductor electric wirelines of up to 9,100m (30,000ft). Located between the inter-tool communications bus and the Wireline Uplink, it controls the collection of data from the tools below and packages it for transmission to the surface system. It receives commands from the surface system via the fast downlink and provides responses back to the surface as required. The TCU also houses the main downhole power supply providing power to the logging tools.
