1 INTRODUCTION
NOTICE
This user manual describes the METIRIO encoder, basically the METIRIO read-
head and the alignment to scales. Where applicable, the deviating specifications
of the METIRIO A1 housing variant are given. Custom made external housings or
available accessories are not described in this user manual.
1.2.2 METIRIO accessories
SmarAct Metrology provides several accessories for the METIRIO encoder, which come with their
own user documentation. Here we just give a brief overview of available accessories and their
intended use.
Figure 1.2: ENCODER INTERFACE MODULE
The following accessories are available:
• ENCODER INTERFACE MODULE (IM): This is an electronic interface adaptor to digitize the
analog output signals of the METIRIO Readhead and convert them to standard quadrature
signals, if the customer’s controller is uncapable to interprate the analog signals. The IM can
directly be connected to the METIRIO A1 D-Sub 15 connector.
• ENCODER EVALUATION MODULE (EEM): The EEM is a box that can be connected to the stan-
dard D-Sub 15 plug of the METIRIO A1 on the one side and via USB to a PC on the other side.
It is a tool to quickly interact directly with the I
2
C interface of the readhead in order to set
the electrical settings and store them to the readhead’s internal memory. This tool does not
replace a motion control system and does not calculate positions from the readhead signals.
The METIRIO can also be addressed directly by any controller that provides the I
2
C interface,
but utilizing the EEM gives a direct and simple approach.
• ENCODER EVALUATION PROGRAM (EEP): This software is used in combinatin with the EEM
and provides a graphical user interface to communicate with the METIRIO Encoder and vi-
sualize the analog signals for a quick adjustment.
