WREM 81 MTM(VR)
RFID reader 13,56 MHz, 125 kHz

Introduction
RFID reader WREM 81 MTM(VR) with wiegand output, reads media at 125 kHz (EM
Marin) and is designed for connection to control modules and door controllers of the
APS mini Plus or APS 400 system, or to third party controllers. The reader is equipped
with a configurable WIEGAND data output usable with most third party systems. The
reader is delivered in MTMRFID module dedicated for entry panel MTM. It contains two
inputs (LED and buzzer control), as well as an
RS 485 interface for configuring the wiegand output or fw update.

e. Block diagram
The WREM 81 MTM(VR) reader is a module for a modular MTM entry panel. MTM entry panel itself is part of the home
intercom system, it has its own power supply and bus for receivers. WREM 81 MTM(VR) has its own cabling,
configuration bus and wiegand interface for door controller or APS mini Plus or APS 400 reader module or third party
wiegand controller. Plus.
•The reader sends a code representing the ID medium via the wiegand interface to the MWGD 82 door
controller.

•The reader can be configured via the RS 485 bus using the APSUSB converter and the program
APS Reader.

2.2 Installation instructions
2.2.1 Reader installation
The WREM 81 MTM(VR) reader is already delivered in the MTMRFID module. It contains short 0,4 m long wires. Check
for any voltage drop on the supply wires so that it is not below Vin min. Use a separate pair of UTP cable (if used) for each
Wiegand signal, do not connect the W0 and W1 signals together in one twisted pair. Follow the MTM entry panel manual
regarding the assembly.
2.2.2 RS 485 bus
It is recommended to bring a twisted pair for the RS 485 interface into the switchboard, to be able to update firmware or
to configure WREM 81 MTM(VR). On the contrary to wiegand interface, this bus must be connected in one twisted pair.
The actual configuration is performed using eg the APSUSB converter and the APS Reader program.
2.2.3 Radio signal interferences
If a product variant should read 125 kHz, it is necessary to take into account another 125 kHz reader in direct range - for
example by both-sided door control. 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, avoid mounting on metal substrates, it is recommended to perform a practical reading test or contact
[email protected].
Interference along the line, eg 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 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.

4.1 Connection possibilities WREM 81 MTM(VR)
Reader module can be connected as follows:
▪FIGURE A: Configuration and firmware update.
To configure the reader or update the firmware, it must connect to the converter, eg APSUSB or APSLAN and use
the desktop application APS Reader.
▪FIGURE B: Connection WREM 81 MTM(VR) to the wiegand door controller
The Wiegand output of the reader is connected to the Wiegand input of the door controller, eg MWGD 82 or
MWGD 46. Do not pull the wiegand interface W0, W1 in one twisted pair of UTP cable, use two, one pair for
each signal. The power supply is in range of 8 -28 Vdc, please use the signal wires for LED and buzzer control if
needed. These can be connected and controlled by only one wire from MWGD 82.

▪FIGURE C: As part of a multi-module MTM entry panel, simply connect the 4 wires of the reader module.
When connecting the WREM 81 MTM(VR) to the MTM entry panel, you can use your own access control system
power supply. Connect the wiegand interface & power supply (minimum), and if possible, the signal for LED and
buzzer control and bring the RS 485 wires to an accessible place for possible update fw or configuration.
