MREM 81 MTM(VR)

RFID module 125 kHz

Introduction

RFID reader module MREM 81 MTM (125 kHz) with integrated controller for one door

control is designed either for connection to the RS 485 bus of the APS mini Plus access

system or for autonomous operation. The module is also equipped with a Wiegand

interface for connecting an input RFID reader with a Wiegand output for possible both-

sided controlled door. Up to 32 MREM 81 reader modules can be connected to one RS

485 communication line of the APS mini Plus system. The module is dedicated either

as a standalone or as a part of modular entry panel MTM from CAME.

e. Block diagram

The MREM 81 MTM(VR) reader module is a module for the MTM modular entry panel. MTM entry panel itself is part of

the home phone system, it has its own power supply and bus for phones. MREM 81 MTM has its own cabling, data bus

of the APS mini Plus access system and the power supply can either be used from the MTM panel or have a 12V / 24V

power bus for the APS mini Plus access system.

▪Complete door control; lock control (open drain), door contact input, exit button, alert notification to PC or Cloud,

wiegand input, system bus, power supply. The reader module can operate autonomously or as a part of the

system.

▪Connection on the RS 485 bus with control from a mobile phone from the WebHit cloud application. Up to 32

reader modules can be connected to one APS mini Plus line.

•How to connect in ‘‘star‘‘? Using the REP 485 line repeater.

2.2 System bus

2.2.1 RS 485 bus termination

If the reader module is the last one on the bus, it is advisable to terminate the RS 485 system bus so that there is no

reflection on the line. Use the termination resistor 150Ω which is a part of the packaging.

2.2.2 RS 485 idle states

This reader module does not allow to set the idle states of the system bus. Set the idle states on converters APSLAN,

CON 110.IP or REP 485 if needed.

2.3 Assembly

2.3.1 Radio signal interferences

If a 125 kHz reader is used, it is necessary to take into account another 125 kHz reader in direct range - for example when

checking the door on both sides. In this case, the readers may interfere with each other. In the techfass system, it is

possible to use the so-called synchronization of reading between the reader and the reading module, which then do not

interfere with each other.

In general, if possible, we avoid mounting on metal substrates, it is recommended to perform a practical reading test or

contact support@techfass.cz.

Interference along the line, e.g. from an interfering power supply, can affect the reading distance or the reader's own

communication.

3RFID reading

3.1 Reading at 125 kHz

The device can read media on a frequency of 125 kHz like EM Marin (e.g. EM4200, EM4305). Next example of

supported media technology is Jablotron ID.

125 kHz settings possibilities:

Default settings for 125 kHz.

4 Wiring diagram

4.1 Connection possibilities MREM 81 MTM(VR)

Reader module can be connected as follows:

▪USECASE A: Reader module configuration and settings.

If we want to set the reader module and its parameter values, eg what frequency it should read, what HW

address it should have, whether the lock is reverse or standard, etc., it must be connected to the converter, eg

APSUSB or APSLAN and use the desktop application APS Reader, or to CON 110.IP and use the WebHit

application website.

▪USECASE B: System-wise, where the individual reader modules are connected to the RS485 bus, where up to

In this case, the reader module is independent on the entry panel, it can operate autonomously or as part of the

APS mini Plus system. The actual configuration of the module and its settings can be performed using the

APSUSB converter and the APS Reader program.
