Ultrawire Crossover (XTU)
The XTU Downhole Controller is a communications interface between logging tools operating on the Ultrawire™ toolbus and Ultralink™ telemetry system.
The XTU is an intelligent bridge between the Ultrawire™ toolbus and Ultralink™ telemetry system; acting as both a communications interface and a programmable logging controller.
Features & Benefits
- Automatic "plug and play" configuration and start-up
- Selectable Ultralink™ bit rate to suit varying demands & conditions
- Detailed toolbus error detection and logging to facilitate fault finding
- Facility to monitor the head voltage and internal temperature of the XTU
- Automatic transmission of the toolstring configuration to the surface system
- Automatic downlink failure detection triggers reversion to default bit rate
- Automatic generation of a default polling program that enables all the identified tools to share the available bandwidth on the wireline
