Product Overview
The TeleMyo™ 2400T Direct Transmission System (DTS) for EMG and other biomechanical sensors directly transmits data from the electrode or sensor site to a belt worn receiver. This direct transmission concept greatly simplifies the arrangement of EMG measurements by eliminating the need to arrange cable connections between the EMG electrodes and EMG amplifier. The small light weight probes are also beneficial for small subjects like children and small animals.
The Belt Receiver can operate in 3 modes:
- Direct connection to any PC via USB connection (transmission range 10m)
- Wireless retransmission of signals in real time to any Noraxon USB receiver
(transmission range up to 100m)
- Data logging via Flash Memory card
  
This unique concept gives you flexibility to operate the DTS system without limitations. The compatibility to Noraxon’s USB receiver systems, operated via WiFi based retransmission of data, allows you to integrate up to 8 additional stationary analog input signals (isokinetics, force plates, etc.) and optional analog output of all signals (to e.g. connect signals to 3D kinematic systems).
The DTS system can operate any configuration between 4 and 32 channels (2 Systems). The default system is equipped with EMG preamplifiers but can be upgraded with other biomechanical sensors like goniometers, Inclinometers, foot switches, and accelerometers. A wireless synchronization system can be used to accurately synchronize the TeleMyo DTS System to other biomechanical devices.
Operation Modes of Belt Receiver
Dependent on functionality aspects within your experiments you can configure and operate the TeleMyo DTS systems on 3 operation levels:
1. Direct USB based connection of Belt receiver to the PC
In this mode the DTS probes send the data to the Belt receiver which is located directly besides the PC. An USB connection arranges the real time access of all transmission data to the PC and data acquisition software. The transmission range is up to 10 meters.
2. Retransmission of data from Belt receiver to desk receivers
This mode operates a second (real time) transmission of data via WiFi to any of Noraxon’s desk receivers (PC interface Receiver, Mini Receiver or Analog Output Receiver). This expands the transmission range up to 100 meter in line-of-sight. If the Mini Receiver is used, up to 8 additional analog input channels can be connected which allows you to integrate signals from stationary devices like Isokinetics or force plates.
3. Data Logging Mode via Flash Memory card
By exchanging the retransmission WiFi board with a Flash Memory Card the system can be used as a data logger at any time. Commercial Memory Cards up to 8 GB guarantee enormous data logging capacity. An easy and comfortable import routine transfers data to the Noraxon analysis software MyoResearch XP.
