1 Introduction
MCR series are high performance and flexible ISO14443-A OEM contactless smart card readers
supporting read-write capabilities. The readers are based on the 13.56 MHz contactless technology
and are fully compatible with the entire MIFARE® family, as well as supporting ISO14443A
contactless standard. The readers come with Ethernet connectivity and have extensive software
support package that is optimized for easy integration.
2 Server & Client Protocols
MCR Ethernet Terminals can be used in either Client or Server. In client mode the terminal connect to
a remote server that it listening a TCP/UDP port. Server may accept multiple connections. MCR
Terminals can be used as Server. The terminal listens own port and can accept a connection request
from outside. In this case terminal’s IP number is to be static. It depends on the application whether
the terminal is in Client or Server mode.
2.1.1 TCP/IP Client Mode Operation
When the terminal is set to operate in client mode it tries to connect a remote server IP & Port set in
configuration.
2.1.2 TCP/IP Server Mode Operation
When the terminal is set to operate in server mode it listens own TCP port to accept outcoming
request from other clients.
3 Terminal Setup & Settings
The terminal can be configured on a network (LAN). To start setup terminal must be in a network that
supports DHCP. The terminal needs to acquire an IP from a DHCP server on your network.
Configuration is made through and UDP protocol so it advisable to use a firewall free network. Most of
the firewalls filter UDP.
For the first time setup you can use miFinder software. miFinder can discover all terminals on your
network. After MCR0x is up i.e. (after gained an IP from your network) you can use miFinder. It is also
advisable to turn off any firewall & antivirus software before running miFinder. As stated before,
firewalls on PC may prevent to discover the network.

3.1 miFinder Configuration Software
Using miFinder you can set various parameters related to terminals. Some parameters are specific to
each terminal and some parameters are global to all terminals. After all setup, your device is listed or
discovered as given below.
If your terminal is not discovered, press Discover button again.
miFinder Main Screen
In main window of miFinder you can the following parameters
•Restart or Reset all terminals connected to network.
•Setting DHCP parameter of all terminals connected to network.
•Setting the baud-rate of RS232 / RS485 / USB port.
•Setting the Real Time Clock of all terminals connected to network.
•Setting the Client mode type: Web or Normal Socket Client of all terminals connected to
network.
•Setting the remote parameters or firmware update of all terminals connected to network.
•Setting the remote NTP server parameters of all terminals connected to network. NTP server
can be used to set automatically if the device can access internet (www).
•Enter to update mode to check firmware update of all terminals connected to network.

miFinder main window view
To enter a detailed setup of a particular terminal select a device from the list and double click to see a
particular terminal setting window in miFinder. This window gives you a detailed setup of each
terminal. Please note that these settings are specific to each terminal. Below given a snapshot of
detailed settings window of miFinder.
miFinder Terminal Setting Window
This setting window gives you to:
•Set the terminal IP static or dynamic
•Set protocol type of operation of the terminal: UDP or TCP

•Set UDP remote ip & port
•Set TCP operation mode: Client or Server
•Set TCP remote ip and server port
•Set remote request file with GET in Web-Client mode
•Set / Clear Relays to test
•Give a alias name to terminal (i.e. MCR_Gate1 etc.)
•Set & View LCD Screen Texts ( App. Specific section )
3.1.1 Automatic IP (DHCP) Mode
In miFinder’s main screen, in Set DHCP Mode section, select ON and press Set DHCP Mode button.
Then all terminals restart and try to access a DHCP server to get an IP address from your network.
Please note that your network must have a DHCP enabled management device.
DHCP Mode Setting
3.1.2 Constant / Static IP Mode
The terminal is set up with the following IP parameters for static operation at factory.
Parameter
Value
IP Address
192.168.1.100
Gateway Address
192.168.1.1
Net Mask
255.255.255.0
Primary DNS
192.168.1.1
Secondary DNS
192.168.1.1
However, most of the terminals manufactured are set to operate in DHCP mode. Static IP mode is not
preferred for mass productions. The default setting for all terminals is DHCP.
To set a terminal to be run in static IP mode, in miFinder’s main window enter the desired terminal’s
settings screen. Then enter your desired IP, GW, Mask and DNS values in Device IP Settings section.
IP Parameters Settings Section
Note that, after opening settings screen, this section gives your terminal’s current IP parameters. After
entering the values as above figure, then press Set IP Settings button. Then the terminal restarts
again.
The last step is to set DHCP mode to OFF in main window of miFinder as given in Figure-4. The
terminal restarts again in Static IP mode. Please note that you can skip this step if your terminal is
already operating in static IP mode.

3.1.3 Client and Web Client Modes of Operation
Any MCR0x terminal can connect to web server or server as client. The terminal’s client mode of
operation can be altered in main screen of miFinder as in Figure-6.
Web Client or Normal Client Mode Setting
When a contactless card is detected by the terminal, it tries to send card’s UID to server as follows:
Operation Type
Example Terminal Request
Web Client
GET /request.php?devID= MCR04-1000&UID=F0C189A5
Client ( Socket )
MCR04-1000,UID=F0C189A5
It is seen that the terminal tries to send data to a web-server by requesting a PHP file. You can also
change this request in miFinder’s setting window.
Http request file name for Web-Client Mode
HTTP1.1 mode with host domain
GET /request.php?devID=MCR04-1000&UID=04286CD29C3981 HTTP/1.1
Host: login.mitrack.de

3.2 Message Formats from Server to Terminal
The message format from server to terminal is given by the following syntax.
<Device ID>,<CMD1;parameter1;…;
10
arameter>,<CMD2;parameter1;…;
10
arameter>,…
This packet can be sent by a specific TCP server via socket_send API’s or simple echo statements
defined in a web server protocols.
