Product Overview

The TeleMyo™ 2400T G2 Transmitter is the latest generation of surface and fine-wire telemetric EMG systems that sends real-time EMG and other analog signals up to 300 feet (100 meters) by wireless transmission to a desktop computer or notebook. It combines high-quality, scientifically reliable data with mobility, flexibility and ease-of-use for clinicians, researchers, sports medicine professionals, ergonomists and athletic trainers. The default system includes a 4, 8, 12 or 16 channel transmitter unit, a USB based PC-interface receiver box, active pre-amplified leads, battery charger, and a belt clip and pouch for easy use. The default system comes fully equipped with four, eight, twelve, or sixteen active EMG leads.

The option of purchasing an additional transmitter expands the system up to 32 channels for any combination of EMG and other analog signals. Virtually any analog sensor that is battery operated and works within +/- 5 volts can be connected directly to the system, such as foot switches and goniometers. In addition to the on-site pre-amplifiers, the "active leads" use NORAXON's patented signal amplifier technology, which provides clean, consistent and reliable data. The system can also be used as a data-logger when the WiFi board is exchanged with a flash memory board (up to 4GB).

Receiver and Wireless Sync-Trigger Concept

Noraxon’s second generation of telemetry systems (TeleMyo 2400T “G2”) offers a unique concept to receive and combine telemetric data with other biomechanical devices. Three models are introduced below, which can be upgraded at any time:

1. PC Interface Receiver

The default receiver is the PC-Interface Receiver. It can receive WiFi based telemetry data up to 32 channels and forward the data via USB to the PC. Due to USB functionality, it installs easily, bypasses the need for any Window network configuration and runs on any Desktop PC, notebook or Windows release (Win 2000, XP, Vista).

2. Mini-Receiver

The mid-level receiver model is the Mini-Receiver. It includes 8 additional analog input channels, which are needed for stationary devices like Isokinetics, force and contact plates and light gates. It allows the combination of mobile telemetric data collection with stationary systems without losing the wireless functionality. All data are forwarded to the PC via USB connection. The Mini-Receiver is preconfigured for Wireless synchronization functionality which can be ordered as an extra option (Wireless Sync-Trigger Kit).

3. Analog-Input/Output 2400R Receiver

The top level receiver option is the Analog Input/Output 2400R Receiver. It has the capacity to convert all telemetric data to analog output data, which again can be connected directly to third party devices like 3D motion capture systems. The Analog Input/Output 2400R Receiver includes 8 analog inputs and the standard 16 analog outputs can be upgraded to 32 channels. The Analog Input/Output 2400R Receiver System includes the Wireless Sync-Trigger Kit. The Analog Input/Output 2400R Receiver is the most flexible investment for biomechanical labs because it can simultaneously manage telemetric data, stationary analog input data, analog conversion/connection of telemetry data and any need related to trigger-based synchronization of involved measurement devices.

4. Stand-Alone Funk-Sync-Trigger System

The stand-alone Wireless Sync-Trigger System upgrades the PC-Interface Receiver and older TeleMyo Systems with a telemetric trigger system. This permits a time-synchronized start of data collection with the TeleMyo 2400T and any third party device in your lab.
