What This Manual Covers
This manual contains information on the CerePlex Direct, a plug-and-play biosignal data
acquisition system. The system is designed for use with many of Blackrock’s CerePlex digital
headstages and is compatible with the NeuroMotive video tracking system. The CerePlex Direct
is capable of recording from 16, 32, 64, 96, 128, or 256 channels over 3 headstage input banks,
depending on the model.
Figure 1 - CerePlex Direct Data Acquisition System
This manual will cover the system requirements, associated software, and an overview of the
system’s hardware features. Note that the CerePlex Direct is offered in a number of system
packages, so the exterior packaging may be labeled with a different part number than listed in
this document.
For questions on this product or any other Blackrock products, contact our 24/7 support service
at support@blackrockmicro.com.

Warnings and Precautions
Do not use with devices not approved by Blackrock Microsystems.
Do not touch any exposed electrical conductors or use damaged digital data cables
when using the CerePlex Direct.
Keep cables out of traffic paths. Injury to user or patient can occur.
The user/patient/subject should not attempt to open the CerePlex Direct.
Use caution when operating the CerePlex Direct, especially when connecting and
disconnecting cables to minimize risk of CerePlex Direct falling and/or injury.
Do not rest objects on or against the CerePlex Direct.
Avoid strong static discharges from sources like television or computer monitors; they
may damage the electrical components of the system.
Always operate the CerePlex Direct system in a clean environment.
Keep the CerePlex Direct system away from liquids. Contact with water, shower spray,
or wet surfaces can result in a device malfunction and/or electrical shock.
Connection of external instruments to the CerePlex Direct may compromise electrical
safety.
Always use antistatic or electrostatic discharge (ESD) safe gloves when connecting the
CerePlex Direct.
Use only Blackrock Microsystems supplied components (CerePlex Direct, CerePlex
Headstages, Blackrock Microsystems Cables and Adaptors). Substitution of components
not supplied by Blackrock Microsystems may affect system performance and patient /
subject safety.
Do not leave the patient / subject connected to the CerePlex Direct when system is not
in use.
Plug in all connections and wires to the patient / subject and the system prior to
powering on the CerePlex Direct.
Power off the system prior to removing or disconnecting any cables from the patient /
subject and the system.
Regularly inspect cables for compromised insulation or bad connections. This can help
prevent electrical shock as well as data corruption.
Read this entire manual prior to using the device.

Setting Up the CerePlex Direct
The software CD included with the CerePlex Direct contains two executable installers:
CerePlex-Direct-Central-Suite-7.X.X.msi installs the CerePlex Direct Software Suite and USB
drivers for communicating with the CerePlex Direct. The latest version can be downloaded from
the ‘Software Downloads’ section of the Blackrock Microsystems website.
MCRInstaller-7.16.exe is the MATLAB Compiler Runtime installer—this is required to use
Central’s custom digital filter editor.
NOTE: Before installing: make sure the CerePlex Direct is not plugged into the PC with the
USB A-B cable. Installing the CerePlex Direct Software Suite with the CerePlex Direct
connected to the host PC may result in driver installation issues and cause the host PC to fail to
recognize the CerePlex Direct. If this happens, please refer to the ‘Troubleshooting’ section of
this manual or contact Blackrock Support.
Figure 2 - CerePlex Direct Driver Installer
To start the installation process, run CerePlex-Direct-Central-Suite-X.X.X.msi and follow the
onscreen instructions from the installation wizard (as shown in the figure above). After installing
the software, the CerePlex Direct can be connected to the host PC via the USB A-B cable.
When plugged into a USB port for the first time, the CerePlex Direct will install the device
drivers. Windows will re-install these drivers when the USB port is changed.
If you intend on using Central’s custom digital filter editor to create your own filters, you will
need to run MCRInstaller-7.16.exe.

Overview of Hardware
The CerePlex Direct is a non-real-time data acquisition system that collects data from up to 256
digital data channels, 3 analog inputs, and a 16-bit digital input. Data is sampled at 30,000
samples/second and transmitted over hi-speed USB to a host PC with a bandwidth of 50 Mbps.
The CerePlex Direct is designed to have several isolated ground planes. The CerePlex Direct
chassis is tied to earth ground through the ground pin of the power plug. Patient ground is found
on the digital headstage connections and the touchproof ground connector on the front panel. It
is not recommended to bridge these isolated ground planes; it can introduce noise into the
signal and compromise the safety isolation of the patient circuitry.
