Document Overview
This document describes the specifications and features of the LabLynx. It also explains
how to set up, test, and use your LabLynx.
LabLynx Overview
The LabLynx is a portable, battery powered digital acquisition system. It is capable of
recording from up to 256 individual electrodes using Neuralynx digital multiplexing
(mux) headstages. The physiological signals are digitized at the Neuralynx mux
headstage and transmitted wirelessly from the LabLynx. Wireless communication uses
5 GHz WiFi (802.11 ac).
Features:
•Wirelessly transmit up to 256 channels
•Record up to 256 channels to microSD card
•Record from up to four different digital (mux) headstages
•8.5 hour wireless run-time
•7 hour charge time
•Time synchronization with Cheetah to within ±5 ms
•30 KHz Sampling Rate
•16-bit Resolution
•±5 mV Input Range
•>80 dB Common Mode Rejection Ratio (CMRR) at 60 Hz
•<2.5 µVRMS Noise (0.1 Hz to 8 kHz)
•Up to eight TTL-compatible digital IO
•Compatible with Neuralynx FLEDs
•Compatible with Neuralynx EIBs
•Compatible with Neuralynx mux headstages

Setup
The LabLynx communicates wirelessly with a PC running Cheetah. A standard LabLynx
license for Cheetah is non-transferrable. Your LabLynx license only allows use of
Cheetah with a LabLynx. If you purchased your LabLynx with a PC, your system would
be pre-configured. If you already own a standard Neuralynx Cheetah license, the
LabLynx can be used with Cheetah. The LabLynx requires Cheetah 6.4 or later.
LabLynx supports up to 256 channels. The number of channels that can be viewed and
recorded in Cheetah depends on the Cheetah license.
If you need to change the order of acquisition channels or reduce the number of channels
recorded, see section 4.6 Channel Mapping and Channel Masking.
Electrostatic Sensitive Equipment
All Neuralynx equipment is sensitive to electrostatic discharge (ESD) and should be
handled appropriately. Always wear a static wrist strap and use appropriate ESD
measures when handling any electronics. If you have questions, please contact Neuralynx
for more information.

Hardware Setup
To connect a LabLynx directly to a PC first check to ensure the PC meets the minimum
system requirements. These are outlined on the Neuralynx website in the support section.
Next, follow the diagram below to ensure you connect the necessary hardware, and then
follow the steps identified to ensure the LabLynx Connects to the PC through the wireless
access point. It is recommended that the Ruckus Router wireless access point be mounted
on the ceiling for best performance.
