NSE - Model 19” 2U -Topside Wireline Telemetry System
The NSE Wireline Telemetry System facilitates communication via wireline or powerline through its two primary components: a topside unit and one or more downhole modems. This system acts as a transparent link, enabling seamless interaction between the topside user interface/applications and the downhole tool electronics. Commands initiated from a computer to the topside modem are modulated and transmitted over the power cable; subsequently, the downhole modem demodulates and converts them back to standard serial commands, such as TTL or CANBus. The TS Telemetry Portable Unit's compact design allows for flexible mounting options and can function independently or within an integrated system. It offers dual connectivity options for wireline and DC inputs. Worldwide use of the NSE Wireline Telemetry Systems spans applications from high-power tools like tractors and strokers to low-power sensors and data acquisition tools. The system is known for its reliability in noisy environments, optimizing data rates suited to specific operational setups with minimal user input. The modems autonomously adjust to proper gain and frequency settings and adapt continuously to maintain optimal signal-to-noise ratios. This adaptive capability also allows for multiple downhole modems to communicate with a single topside modem, and the system supports a broad range of input voltages.
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.
