Strict security measures
Advanced security function option (/ AS) corresponding to strict requirements for data management

SMARTDAC+ GX /GP/GM advanced security function option (/AS) provides safe and traceable data management in applications such as pharmaceutical manufacturing, biotechnology, health management, and medical institutions.
The advanced security function supports the strict requirements of US FDA 21 CFR Part 11, EU-GMP Annex 11 and other associated guidelines for data management.
It also supports data integrity in accordance with ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) mentioned in PIC/S, WHO, MHRA and FDA guidance documents.

FDA 21 CFR Part 11

What is "ALCOA +"?
It refers to A: attribution, L: legibility, C: simultaneity, O: originality, A: accuracy, C: completeness, C: consistency, E: Persistence, and A: Availability. ALCOA + is a requirement for data integrity guidelines of PIC / S (Pharmaceutical Testing Contract and Pharmaceutical Testing Joint Scheme), WHO (World Health Organization), MHRA (Pharmaceuticals and Drug Regulatory Authority: UK), and FDA (Food and Drug Administration).


Secure electronic records

Measured data, settings, and operation logs are saved to a single encoded binary file. Encoded data in binary format offers a high level of security because it cannot be opened in most text editors.
If the data files are damaged or tampered with, SMARTDAC+ Standard Universal Viewer software will identify the nonconformity and notify the user accordingly.

Security data file transfer

SMARTDAC+ can automatically transfer data to an FTP server. FTPS, which encrypts data transferred via FTP using SSL, is also supported, allowing data files to be transferred safely.

SSL-based encryption

Electronic signature(data record signing) function

Measurement data can be displayed and confirmed on the GX/GP (only the data in the internal memory) or the SMARTDAC+ Standard Universal Viewer software, and an electronic signature can be applied to that data. Three levels of signature are available: operator, supervisor and quality control. The signature along with information such as pass/fail and comments can be saved to the data for review and audit.

*Electronic signature to the GM is possible only from the SMARTDAC+ Standard Software. Electronic signature cannot be applied through GM's web server.

Sign Record

Logical security

Data integrity requires that the right users have access to the right information.
SMARTDAC+ can create users with various access privileges.

  • Four main security levels (two separate administrator roles, user and monitor user).
  • Up to 200 persons can be registered.
  • Process owners/ system owners can be given access rights to functionality appropriate to their role.
  • For the password, a minimum string length and a minimum policy complexity can be set.
  • Centralized management of user names and passwords using servers on the network is possible through ActiveDirectory.

Logical Security

Audit trail function

The SMARTDAC+ operation log is saved to a file along with measurement data.
When settings are changed, it is possible to record the reason for the change along with the setting change operation. In addition, checking the details of setting changes from "setting difference operation history" makes greatly reduces the data checking work during audits.

Audit trail function


Free dedicated software download

SMARTDAC+ Standard Software is possible to display measurement data, display the operation log, and configure the GX/GP/GM. It is also possible to sign in data using the SMARTDAC+ Standard Universal Viewer.

Universal Viewer software

The Universal Viewer software can display data files in various forms such as waveforms and numeric values. It can display and print not only measurement data but also alarm and message lists and operation logs. With the operation log, a comparison of the settings before the change and those after the change can be displayed, allowing you to check the changes in detail.
It is also possible to sign the data by entering the user name, user ID and password after confirming the measurement data. If the data has already been signed, you can sign at a different level after confirming the signature state on the screen.

Universal viewer

Hardware Configurator software

Hardware Configurator software allows for offline system configuration which can be imported via SD memory or external storage media as well as Ethernet communication. System settings can be printed in a table format to support GX /GP/GM system validation (IQ/OP/PQ).
In addition, a pair of selected setup data files can be compared, and their differences can be displayed and printed in table format.

The SMARTDAC+ GM is used extensively for data acquisition in various kinds of conveyance equipment including automobiles, industrial vehicles, in-plant vehicles, ocean shipping vessels, and automated materials handling systems. In addition to being compact and not requiring a PC for data acquisition, the SMARTDAC+ GM can be run under DC power and be operated under harsh conditions (-20° to 60°).


In semiconductor manufacturing processes, a deficient clean room environment can lead to defects and wasted resources, making a strictly controlled clean room indispensable. Maintaining the environment in the clean room requires control of air filters, HVAC systems, room temperature, humidity, airborne particles, and other factors.


Industrial hydrogen fuel cells can be used to produce hydrogen and oxygen from distilled water as well as run in reverse to generate electricity. Fuel cells can also be used in conjunction with intermittent energy sources like solar or wind to provide regulated continuous energy output.


The SMARTDAC+ GM10 is employed by customers who are device manufacturers when they deliver a device to the end user, for on-site monitoring to check that the delivered device is operating stably. If settings are made to the SMARTDAC+ GM10 in the office beforehand, then all that is necessary is to take it to the site and begin data acquisition thus, anyone can conduct on-site data acquisition.

  • For remote monitoring (of temperature, pressure, and flow volume), installing the SMARTDAC+ GM in the plant and the SMARTDAC+ GX in the office provides for a scalable, pc-free on-site data monitoring solution.
  • You can centralize management of large quantities of data by automatically transferring acquired data to a FTP server.

Data acquired on the SMARTDAC+ GM can be easily monitored through the company network, even from remote locations.
