Z-Series BioAmp Base Station

RZ2

RZ2 Z-Series Base Station

The RZ2 processes and filters acquired signals and can be used to control digital I/O and/or generate analog signals. Designed for up to 256-channel data acquisition, the RZ2 is the first in TDT’s Z-Series line of ultra high performance processors. Z-Series processors feature two, four or eight ultra fast digital signal processors networked on a novel bus architecture that speeds both onboard communication and memory access. Faster clock speeds and enhanced processing power not only improve channel count, but also allow for simultaneous acquisition on all 256 channels at sampling rates up to ~25 kHz and up to ~50 kHz on up to 128 channels. High bandwidth data is streamed from a Z-Series PreAmp to the RZ2 over a fast fiber optic connection. Our innovative Optibit optical PC interface ensures fast and reliable data transfer from the RZ2 to the PC. The RZ2 also features 16 channels of analog I/O, 24 bits of digital I/O, two legacy optical inputs for Medusa PreAmps, and an onboard LCD for system status display.

For researchers who wish to transfer data across a network to another PC, we offer an optional RZ UDP Ethernet interface.

The RS4 Data Streamer is also available for storing data streamed from the RZ2. Off-loading data streaming tasks from the RZ2 to the RS4 improves real-time performance and allows you to acquire continuous data over several days or weeks.

The RZ2 is rack mountable in a standard 19" rack and is 3 U (5 1/4") tall.

	TDT systems are compatible with a wide variety of electrode types, including stereotrodes and tetrodes, microwire arrays, metal microelectrodes, acute and chronic NeuroNexus probes, surface electrodes, multi-electrode caps, and needle electrodes.

	The RZ2 is a highly optimized version of our very successful RA16 and RX5 BioAmp processors. More power? The numbers speak for themselves…

RZ UDP Interface: The RZ Communications Interface is an optional interface for RZ processor devices that includes a UDP Ethernet connection and a serial port connection.

The serial port can support baud rates up to 115200. The port is a standard 9-pin RS232 connection located on the back of the RZ and occupies one o the RZ's DSP expansion slots. The RS232 port can be directly connected to any device that communicates via serial port, such as head trackers, eye trackers, or a PC.

The UDP interface is designed to transfer up to 200 data values at low rates to or from a PC. The PC may be directly connected through a dedicated Ethernet card located elsewhere on the user’s network, or even in a remote location connected via the internet. The RZ UDP interface is located on the back panel of the RZ processor and accepts a standard Ethernet cable.

Part numbers:
RZ-UDP-20 UDP Ethernet Interface Card

Technical specifications:

Cable Interface:	Standard Ethernet cable (for direct connections to a PC an Ethernet crossover cable is required)
Speed:	10Mbps
Supported Network Protocols:	DHCP (Dynamic Host Configuration Protocol), UDP, HTTP (for configuration)
Transfer rates depend on data packet size.
