Inline Wireless Sync Receiver
Section 1: Introduction
Brief Description The Inline Wireless Sync feature includes a small and lightweight Sync Receiver and an output
cable to connect to another device. The synchronization function allows signals to be sent from
third party devices or any Noraxon EMG device with wireless sync out capabilities and received
by the Noraxon EMG device. The synchronization pulse is sent wirelessly to the Wireless Sync
Receiver, which is connected to the sync channel of the TeleMyo G2 system or DTS Belt
Receiver.
The Inline Wireless Sync Receiver can be used to receive a pulse meant as a sync pulse or pulse
meant as a marker to signal specific events or times in the record.
Intended Use The Wireless Sync Receiver is intended to allow the signal(s) from the Noraxon EMG device to
be synchronized with signals from other Noraxon devices or third party systems.
Contraindications None

Section 4: General Warnings and Cautions
Risks and Benefits There is no identified risk of physical harm or injury with use of the Inline Wireless Sync
Receiver sensor. The benefit provided by use of the device is the provision of objective measures
to assess the severity of pathological human movement conditions and gauge any subsequent
improvement offered by therapy, training, prosthetic alterations or ergonomic design changes.
Safety Information Summary Warnings 
Do not immerse the Wireless Sync Receiver sensors in any water or liquid
Attention 
The operator must be familiar with typical characteristics of the signals acquired by the
Wireless Sync Receiver and be able to detect anomalies that could interfere with proper
interpretation.

Section 7: Pre-Use Check-Out
Normal Appearance of Signals The Inline Wireless Sync Receiver’s Sync Signal Quality indicator provides a means of
communicating its operational state. A green light means there is a good connection between the
wireless sync transmitter and the sync receiver while a yellow light indicates a poor connection.
Note: If the light is yellow, check that the Wireless Sync Transmitter is turned on.
Attaching the Sensor to a Noraxon EMG Transmitter The Inline Wireless Sync Receiver is connected to the Noraxon EMG system in the Sync port.
The Inline Wireless Sync Receiver has a 4-pin male connector, while the sync port is a 4-pin
female connector.
When removing the Sync Receiver, it is important not to pull on the cable or receiver, but instead
pull the connector straight out from the sync port.
Calibration No calibration is necessary.

IP (Ingress Protection) Rating The Inline Wireless Sync Receiver enclosure has a low ingress protection rating (IP20). The
instrument is not protected against the ingress of water and carries no IPX rating (i.e. is ordinary
equipment). The Wireless Sync Receiver is not waterproof. Care must be taken to avoid
exposure to all liquids. Heavy perspiration may present problems if the Wireless Sync Receiver is
secured to bare skin with an over wrap of tape or elastic belting. In such cases it is advisable to
first add adsorptive material or cloth over the Wireless Sync Receiver before covering the sensor
with tape or elastic bands.

Section 17: Technical Information
Block Diagram Model 234 Inline Wireless Sync Receiver Coming Soon…
Theory of Operation The Inline Wireless Sync Receiver Sensor is designed to capture a pulse sent wirelessly and
transmit that pulse to the attached Noraxon EMG transmitter via a sync port. The sync signals are
then recorded using MyoResearch XP or MR3 and used to start a recording or set markers for
later interpretation. The Inline Wireless Sync Receiver does not use any batteries because it is
powered by the Noraxon EMG system it is attached to.

Synchronization As discussed previously in this manual, the Inline Wireless Sync Receiver can be used to
synchronize the attached Noraxon EMG device with other Noraxon devices (in MR3) or third
party products. However Wireless Sync Receiver is used, it will need to receiver a wireless sync
signal from one of the capable Noraxon devices.
