Description
The NSE Wireline Telemetry System is used for communication via wireline or powerline. The system consists of two main components: a topside unit and one or more downhole modems.
The NSE Wireline Telemetry System operates as a transparent link between the topside user interface/applications and the electronics located in the downhole tool. Serial commands sent from a computer to the topside modem are modulated and superimposed on the power cable. This signal is demodulated and converted back to conventional serial commands (TTL or CANBus) in the downhole modem.
The TS Telemetry Portable Unit is designed to be used stand-alone or integrated into a user system. The compact size of the unit makes mounting and placement of the unit very flexible. Two options for wireline and DC input connections are provided.
NSE Wireline Telemetry Systems are deployed worldwide and cover all applications from power tools, such as tractor and strokers, to low power sensors and data acquisition tools. The reliability of the link allows data transfer in very noisy conditions over difficult cables and the system will optimize data rates for the given setup.
The system requires very little user interaction. In most cases, the modems will autotune to the correct gain and frequency settings for a cable. During operation, the system is continuously adapting to the conditions on the line to optimize the signal to noise ratio.
The system is addressable so several downhole modems can communicate with one topside modem and has a broad input voltage range.
