Logging Function

The logging function is configured with collected data and event logs. 
Collected data: The data collected from measurement devices are 
saved in the internal memory. 
Event Log: Log of EQ100-E monitoring alarm, device alarm, and 
internal events are saved in the internal memory as event log.

Setup Function

The setup file needed for EQ100-E can be created using EQ-Manager 
included in the accessory software. 
The setup file can be written in EQ100-E from EQ-Manager, a web 
screen, or the SD card in which the setup file is stored.

Time 
Synchronization

Synchronization with 
EQ Server

EQ100-E synchronizes time with the EQ Server (PC used as a server).

Synchronization with 
SNTP Server

EQ100-E synchronizes time with the SNTP server.

Network Connection

LAN connection port: The connectable functions/devices are as follows:
A host system (EQ server, EQ-Manager, SMTP server, SNTP server, 
FTP server, and FTP client), a personal computer (web browser), and 
measurement device 
Sub-LAN connection port: Connectable functions/devices are as 
follows: Measurement devices, personal computers (web browser)

Web Function (Japanese, English, and 
Chinese languages are supported)

You can confirm operating condition, operate the EQ100-E, view simple
graphs, and perform maintenance through a web browser on a 
computer connected to the LAN or sub-LAN connection port. The 
operation channel cannot be displayed as a graph.

Taking Out Internal Data File

The following four methods are available:

(1) Collecting by EQ Server

The EQ server collects the collected data and event logs stored in the 
EQ100-E internal memory via the network.

(2) Operations on Web 
UI Screen

The collected data or event logs stored in the EQ100-E internal memory
is downloaded to the personal computer by operations on the Web UI 
screen.

(3) SD Card Output

Any of the following operations outputs the collected data and log files 
stored in the EQ100-E internal memory to an SD card. 
• Pressing the SD card save button on the EQ100-E front side 
• Web UI operations: SD card data output operations 
If the SD card output setting is configured as "Yes" by EQ-Manager, the 
collected data stored in the EQ100-E internal memory is saved on an 
SD card once a day.

(4) FTP Transfer

FTP server and FTP client functions are available. 
• FTP server function: Acquires the collected data files stored in the 
EQ100-E internal memory via an FTP client and the collected data on 
an SD card attached to EQ100-E or an event log. 
• FTP client function: Sends collected data files stored in the EQ100-E 
internal memory to the FTP server from EQ100-E.

Monitoring 
Alarm

Function

Alarm is set off when collected data exceeds the upper or lower limit. 
Output to a general-purpose output terminal is available as well.

Email Notification

Function: Monitoring Alarm Email

Log to Internal Memory

Monitoring alarm occurrence is saved into the internal memory. 
The event log can be checked on the Web UI screen and outputted as 
an event log file.

Status Indication

The monitoring alarm indicator is turned ON.

Device Alarm 
Detection

Function

Detects a device failure, setup/status failure, device failure, 
communication failure, or monitoring process failure.

Email Notification

Function: Device alarm notification email

Status Indication

Lighting, blinking, blinking in long cycles, temporary lighting of the 
device alarm indicator lamp

Log to Internal Memory

An occurred device alarm is saved into the internal memory. It can be 
outputted as an event log file.

Contact Output

Function

An alarm can be outputted through the general-purpose output terminal 
when the monitoring condition is met.

Email 
Notification

Function

• Monitoring alarm notification email: Sent upon a monitoring alarm 
occurrence. 
• Device alarm notification email: Sent upon an occurrence of a device 
failure or an abnormality of setup/status, device, communications, or 
monitoring process of EQ100-E. 
• Periodic alarm: An e-mail with the main text is written by the user is 
sent at a specified time. 
• Test email: Sent by Web UI operations to check the email notification 
settings or the state of communications with the SMTP server. 
Note: The SMTP function with email transmission authentication 
supports: 
• POP before SMTP 
• POP before SMTP(APOP) 
• SMTP AUTH PLAIN 
• SMTP AUTH CRAM-MD5

Maintenance 
Function

Communication Test

Communications with connected measurement devices are 
continuously performed to check stability of the communications with 
measurement devices. Collected data are not saved.

Clock Setting

The time is configured for the built-in clock of the EQ100-E.

General-Purpose 
Output

The general-purpose output terminals of the main unit are operated ON 
or OFF.

FTP Test Transfer

FTP transfer from the EQ100 to the FTP server is tested.

Firmware Update

The firmware of the EQ100-E is updated. The firmware can be updated 
by any of the following methods: 
• By Web UI operations, the firmware is transferred from the PC to 
EQ100-E to update. 
• By inserting an SD card containing the firmware to EQ100-E to update
the firmware.
