Each cable includes a specifications sheet that documents the exact connection made
by the cable together with all necessary interfacing information. Please refer to this
document to pin and connector assignments.
Standalone DI-720 connections
When the MA300 EMG system is used stand-alone – that is, directly connected to
the DI-720 ADC interface, you will use the MA130-DTQ32 cable shown in Figure 3.
This cable has a single 25-pin connector at one end and splits to provide two 37-pin
connectors on the other end. The 25-pin connector should be attached to the Signal
Out connection on the MA300 and the two 37-pin connectors (marked Left and
Right) should be plugged into the appropriate connectors on the DI720 ADC.
Parallel connections
The DI-720 ADC can be used in parallel with another ADC via the MA330 cable –
this allows the MA300 EMG system to supply EMG signals to two separate ADCs
by duplicating the MA300 Signal Out connection. The MA330 cable is connected
directly to the MA300 via the center connector on the cable – each of the two
connectors on the ends of the cable will then contain exactly the same analog signals.
This allows two separate systems to be connected to the MA300 so that (for
example) a motion capture system ADC can be connected, allowing the EMG signals
to be recorded in sync with kinematic and kinetic data, while simultaneously
allowing the DI-720 ADC to monitor and record the EMG signals.
