CYBERAMP 380, COPYRIGHT MARCH 2002, AXON INSTRUMENTS, INC.

In many recording situations, sound is helpful in determining the quality of the recording. Typical

situations include EMG conduction velocity experiments and extracellular spike activity

measurements. To this end, the CyberAmp 380 is furnished with a versatile audio monitor that

samples the signal activity on any of its eight channels or an external input. Two audio modes are

provided: Tone and Click. "Tone" is most suitable for listening to DC levels and slowly changing

signals. "Click" is most suitable for listening to AC activity. Because the audio monitor is an output

device that does not affect the data recorded by the data acquisition system, the controls for this

section of the instrument are manually operated. Thus, the operator can scan the channels, change the

volume or switch off the monitor without affecting the data acquisition process.

The control interface between the host computer and the CyberAmp does not carry the analog data,

but rather carries control instructions to the CyberAmp and status information to the computer. This

connection makes use of the extremely convenient RS-232 serial interface. With this well known

interface, it is easy to connect the CyberAmp to any host computer and its data acquisition system.

To further ease the interface task, the intelligent RS-232 circuitry in the CyberAmp auto matically

conforms to the baud rate of the host computer. There are no complicated switches or jumpers to set --

the CyberAmp simply works at the existing speed and parity of the RS-232 port of the host computer.

For greater convenience, the CyberAmp can be used with data acquisition software that contain

routines to control the CyberAmp. For example, most data acquisition software from Axon

Instruments (pCLAMP, AxoScope) is available with built-in CyberAmp support.

To deal with PC software that does not include CyberAmp support, the CD that accompanies the

CyberAmp provides several possible solutions. First is the Cyber Control for Windows program.

Next a PC-compatible program called CMD300 (short for "Command 300") enables every feature of

the CyberAmp to be set from the DOS command prompt. To use CMD300, shell to DOS from the

data acquisition program, invoke CMD300 with the command line parameters that change the

CyberAmp settings, then return to the data acquisition program. Another solution is the PC-

compatible program QUICK300 that presents the most commonly used features in a convenient

spreadsheet. Also, is a set of C and QuickBASIC language subroutines are included for use by

programmers wishing to add direct support of the CyberAmp into their data acquisition programs.

These software support libraries are not copyrighted, and can be used by owners of the CyberAmp

380 or by third-party vendors of data acquisition software.

Macintosh users should use the CyberControl program included on the CyberAmp software CD.

The basic operation of the CyberAmp 380 is fairly simple. However, the new user should at least read

the Functional Description chapter and the Transducers and Probes chapter to understand the

capabilities of the instrument.

A new CyberAmp 380 should be tested as described in the Functional Checkout chapter (page 11) to

verify that the instrument arrived safely.
