To operate the system:
1) Connect J26 connector of Wave Plus by cable (analog output) to the analog A/D interface of
the external device;
2) If required, connect the trigger cable to the external device. Check trigger electric features
(voltage and timing) adopted by the system (see “Technical specifications” chapter);
3) Connect Wave Plus power supply and switch on the system.
The system can be powered only with Friwo FW7555M/09 power supply provided by the
producer; the use of other power supply units can cause electric shock and damage the
system.
If used in analog mode, the system does not require a Personal Computer; after switching on the base
unit, EMG and basographic signals are available in continuous on analog output connector J26.
4.1.1 Supported external devices
The Wave Plus system can be connected to analog devices commonly used in clinical and scientific en-
vironments; these are the features required by systems:
At least 8 or 16 EMG data collection channels, configured for signals with Zout = 100 ohm and
an amplitude of ± 2,5 V;
At least two analog channels to acquire footswitches, configured for signals with Zout = 100
ohm and an amplitude of + 2,5 V;
If also accelerometer signals has to be transmitted to the analog device, another24 or 48 data
collection channels (3 for each tri-axis accelerometer) are needed;
It complies with IEC 60950.
The use of external devices non-complying with IEC 60950 can cause electric shock and
damage the system. The external devices connected to Wave Plus with an analog
interface, do not have any control over the system acquisition or settings. Any third party
system used with Wave Plus has to be placed out of the patient area, and must be
powered via an isolation transformer or power supply conform to the IEC 60601-1.
