1Document Overview

This document describes the specifications and features of the LabLynx. It also explains

how to set up, test, and use your LabLynx. There is a glossary at the end of the document.

2LabLynx Overview

The LabLynx is a portable battery powered digital Acquisition system. It is capable of

recording from up to 256 individual electrodes through the use of Neuralynx Digital

Multiplexing Headstages, MUX. The physiological signals are digitized at the Neuralynx

MUX Headstage and transmitted wirelessly from the LabLynx via 5G WiFi to a wireless

access point connected to a PC running Cheetah software.

Features:

16-256 Channels

Up to eight GPIO for TTL inputs

8.5 hour wireless run-time

7 hour Charge time

Record from up to four different digital Headstages

16 Bit Resolution

±5mV Input Range

>80dB Common Mode Rejection Ratio (CMRR) at 60Hz

<2.5µVRMS Noise (0.1Hz to 8kHz)

Compatible with Neuralynx FLEDs

Compatible with Neuralynx EIBs

Compatible with Neuralynx MUX Headstages

30KHz Sampling Rate

2.2 Electrostatic Sensitive Equipment

All Neuralynx Equipment is Electrostatic Sensitive and should be handled with

appropriate measures. Always wear a static strap and use all appropriate ESD

measures when handling any electronics. Please contact Neuralynx for detailed

information if you have questions.

2.3 Recommended Additional Products

Neuralynx provides additional products to support the assembly and use of the

LabLynx, and to enhance multichannel electrophysiological research.

2.3.1 Neuralynx Digital Multiplexing (MUX) Headstages

3Quick Start

The LabLynx can be configured to work directly with a PC running cheetah. If the

LabLynx is sold with a PC as a system it will come pre-configured. A standard

LabLynx license for Cheetah is Non-transferrable meaning that Cheetah will only

operate with a LabLynx. If a standard Neuralynx cheetah license is already owned

the LabLynx will seamlessly interface with the cheetah computer.

The LabLynx is configured to work with up to 256 channels out of the box. Actual

channels a user may use is defined by the Cheetah license. To map and mask unused

channels view section 4.4.

3.1.1 Connecting a LabLynx to a PC

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.

Figure 3.1 Connecting Wireless Access point to PC with POE Injector

Step

Function

Connect the 48V Power Supply to a standard wall outlet.

Connect the standard Ethernet Cable to the Ethernet port of the PC

Connect the 48 V Power Supply to the POE Injector

Connect the standard Ethernet Cable to POE Injector

Connect the POE Ethernet Cable to the output side of the POE Injector

Connect the POE Ethernet Cable to the Ethernet port on the Ruckus Router

3.2 Set Ethernet port IP address

To enable the means of communication between the LabLynx and the acquisition

PC a static IP address for the wireless access point must be set. To set the static IP

address follow control panel directory > network and sharing center > change

adapter settings (located on column on left of window) > local area connection

(right click properties) > Internet Protocol Version 4 (TCP/IPv4) > set up IP

address as below image

Figure 3.2 Setting static IP

Next jumbo packets will need to be enabled. From the same properties window >

configure > advanced > scroll to jumbo packets set value to 9014 Bytes.

3.2.1 Clear LabLynx for firewall

If a PC is using a firewall it may get in the way of the LabLynx connecting

to the Ruckus Router. Check to see if there is a firewall in place and if

there is a firewall, disable it from blocking the port connecting the

LabLynx.

3.2.2 Configure Cheetah for specific LabLynx setup

Open Cheetah and select the appropriate configuration for your setup. To

find configuration files follow directory

C:\Users\Public\Documents\Cheetah\Configuration. Open the Cheetah.cfg

using notepad and check that the Acquisition system setup has

LabLynx.cfg unchecked.
