5.3 Body Pack (BP) and Battery

Figure 18: Body pack and battery

The Body Pack (BP) interconnects multiple strings of MTx’s and retrieves their data ensuring exactly

synchronized samples. The collected data is transmitted by an optimized 2.4 or 5.0 GHz spread

spectrum wireless link to the Access Point connected to the PC or via Ethernet cable.

On the top of the Body Pack there are 4 connectors. With Xsens facing upwards, from right to left:

 The large connector is a 5 pin connector which connects to the Battery Pack cable

 The two central connectors are 5 pin connectors to connect to the strings of trackers

 The leftmost connector is planned for future use

On the bottom of the Body Pack, there are 3 connectors:

 One Ethernet connector which can be used for cabled recordings, when the system is directly

connected to the recording PC rather than transferring data via wireless signal

 A micro USB connector, supported for future use to configure the BP

 The 3

connector supported for future use

The BP is powered by a single Battery Pack (rechargeable smart Lithium Ion battery pack). The Battery

Pack has a typical operating time of 9 hours (using the wireless connection) and can be charged using

the provided charger.

5.4 Sync Station

MVN Link (version 4.1 onwards) supports

synchronization with third party devices using a Sync

Station. The figure to the left shows the BNC connectors

of the Sync Station.

Section 7.5 explains how to set up synchronization of

the Sync Station and Section 23 provides more details

and examples with third party systems.

Note that if synchronizing with a third party device sending 5V, it is advised to purchase (from eg Farnell)

a 3.3 - 5V / 5V - 3.3V SMD level translator to prevent damage to the SyncIn ports of the Sync Station.
