73ET/74ET/75ET USERS MANUAL EM-7353-0003B Rev.5
1.
GENERAL DESCRIPTIONS
Thank you for choosing M-System’s Paperless Recording System.
The system consists of a 7xET Series Touch Panel Paperless Recorder, Models 73ET, 74ET and 75ET and RxM
Series I/O Modules, Models R1M and R2M. The 7xET Series, with its functions and operability similar to conven-
tional chart recorders, can easily replace them. It is also a flexible and economical solution, in conjunction with
independent I/O modules which can accept either DC voltage/current, thermocouple, or RTD.
Data are stored electronically on a CF Card. Remote recording via Ethernet is also possible using the PC Recorder
Software MSR128.*
This users manual explains how to install the 7xET Series Recorder, connect to the RxM Series I/O Modules and
operate the Paperless Recorder Software on the 7xET Touch Panel.
If you intend to use the 7xET in the following environments or conditions, redundant and/or failsafe system designs
should be used to ensure the proper degree of reliability and safety.
- Environments or conditions which are not defined in this manual
- Nuclear power control devices, railway control devices, aircraft control devices, transportation vehicles,
fuel control equipment, medical equipment, recreational equipment, safety equipment, and other critical
equipment for which safety must be secured according to relevant laws.
- Those devices which inherently require extremely high level of safety and reliability.
*Explanations regarding the MSR128 given in this manual are applicable to the MSR128-V4, Ver 4.00 or higher. For using the MSR128-V4
or even the MSR128 of earlier versions, refer to respective users manuals.

7xET FEATURES & FUNCTIONS
Model 7xET is a touch panel display, installed with M-System’s Paperless Recorder Software. The Windows-CE
based recording/logging system is most suitable for exporting data to other Windows based applications, such as
Microsoft Excel.
The 7xET transfers, in real time via Ethernet, data from local I/O modules connected via Modbus RTU to a host PC
installed with the MSR128 PC Recorder Software. It can also store data in a CF card, portable and usable on an
independent PC for later analysis.
