Noraxon TeleMyo as Master and MVN Analyze as slave 

For the Xsens system to receive synchronization commands from Noraxon TeleMyo, the 
TeleMyo mini-receive is needed.

5.1.1

 

Hardware connections 

For this set up a BNC connector is required at the Xsens end and a Jack 
connector at the 
Noraxon end. An easy solution is to use a cable with two BNC coax connectors at 
each end, and a BNC to Jack convertor for connecting the BNC to the Noraxon 
hardware. USB cables are required to connect each system to the PC. 
 
Note that if the signal received by the Xsens Sync or Awinda Station is 5V, a 5V-
3.3V SMD level translator is advised to prevent damage to the Station. 
 
Set up the hardware of the Noraxon system as follows: 

 

USB port of TeleMyo mini-receiver to USB of PC. 

 

Connect jack connector to Sync OUT port of TeleMyo mini-receiver to BNC 
connection Sync 

 

IN 1 of Awinda Station. 

 

Manual trigger pulse, jack connector to Sync IN port of TeleMyo mini-
receiver. 

 

Connect the external antenna to the TeleMyo DTS. 

 

When successfully connected and switched on, the TeleMyo DTS will 

display “WiFi ready”.

 

5.1.2

 

Noraxon MyoResearch Software 

Based  on  the  output  settings  described  for  Xsens  software  the  settings  for  Noraxon  
MyoResearch software can remain the same. The difference is that instead of the trigger 
pulse coming from the record button in the Xsens software this now comes from the manual 
button connected to the TeleMyo mini-receiver. Additionally, the mini-receiver should be 
set up as follows: 

 

Go to the hardware menu; 

 

Select the TeleMyo mini-receiver from the list of icons; 

 

Select: settings; 

 

Select: Configure; 

 

Ensure that the wireless sync is “External Pulse” and Input Range is ±5V.

 

o

 

Note  that  a  5V  pulse  can  cause  damage  to  the  Awinda  or  Sync 
Station. For this reason a a 5V-3.3V SMD level translator is advised 
to prevent damage to the Station.
