1 Precautions Before Setup & First Run
•If your network contains managed/smart switches such as (Cisco, Allied Telesis etc.)
•RSTP, STP (Spanning Tree Protocols) and related protocols must be turned off or
disabled from the management console of the switch. These protocols may cause the
terminals to start to gain IP late at first power-on or unable to take an IP address on
the network properly.
•If your network contains a Firewall
•Make sure that your network does not have a MAC-Filter.
•Make sure that UDP 65535 port (terminal discover port i.e miFinder Config) should not
be blocked.
•If your device is unable to gain an IP address from the DHCP server, please define or
give freedom to the MAC ID of the terminal in your network (via management console
of firewall, router etc.)
•Make also sure that TCP ports used by the terminal should not be blocked.

4 Reader Display
The OLED display can be fully controlled by the host. Line status, date time and main texts
can be displayed.
The default texts may be changed using miFinder.exe
Server can display messages using LCDSET command. The display returns to the default
texts after 5s (default) of timeout.

6 Operating Modes
6.1 Server & Client Protocols
The MCRN2P reader can be used in either client or server mode. In client mode the terminal connects
to a remote server that it is listening the TCP/UDP port. The server may accept multiple connections.
The MCRN2P reader can also be used as a server. The reader listens own port and can accept a
connection request from outside.
The reader opens always a server port automatically. The port is +1 of the defined port. For example,
if you set the port to 80, a second server port is automatically opened on port 81.
6.2 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 MCRN2P 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.
6.3 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
Minova Technology GmbH Page 12
D-78628 Rottweil, Auf dem Wall 29
Tel.: (+49) 7 41 / 348 51 564
•Restart or Reset all terminals connected to network.
•Setting DHCP parameter of all terminals connected to network.
•Setting the baud-rate of RS232 / RS485 port.
•Setting the Real Time Clock 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
6.3.1 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
6.3.2 Constant / Static IP Mode
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 above figure. 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.
6.3.3 Message Format
The message format from server to terminal is given by the following syntax.
<Device ID>,<CMD1;parameter1;…;parameterN>,<CMD2;parameter1;…;parameterN>,…
This packet can be sent by a specific TCP server via socket_send API’s or simple echo statements
defined in a web server protocol.
Max. 20 commands can be sent, and each command can have max. 50 chars.
Example:
MCRN2P-1000,RELAY1=1000,RELAY2=2000
The message format from terminal to server is given by the following syntax.
<Device ID>,<ANSWER;VALUE1;VALUE2>
or
<Device ID>,ACK
<Device ID>,NAK
Example:
MCRN2P-1000,UID=4FA20135

8 DESFire Authentication and Auto Read
Internal serial number of a DESFire card can be read using the following configuration. The
authentication settings should be defined according to the card schema. The reader will
perform a DESFire Authentication by selecting the defined Application ID. The read and
parsed data will be returned or used in offline mode.
9 Offline Modes
If the offline mode is activated, the reader logs the activities and sends after it is online again.
Following rules apply:
1- No Authentication, no whitelist. All cards are accepted.
a. Mifare DESFire Card: If authentication settings are defined, the internal serial
number is read and saved. Otherwise, the 7-Byte UID is used.
b. Mifare Classic or other technologies: The 4/7-Byte UID is used.
2- Whitelist activated. In this mode, the serial number or UID is checked.
a. Mifare DESFire Card: If authentication settings are defined, the internal serial
number is read and searched in the whitelist. Otherwise, the 7-Byte UID is
used.
b. Mifare Classic or other technologies: The 4/7-Byte UID is searched in the
whitelist.
3- Authentication Mode. In this mode, all successful authenticated cards are accepted.
a. Mifare DESFire Card: If authentication settings are defined, the internal serial
number is read. Otherwise, the 7-Byte UID is used.
b. Mifare Classic or other technologies: The 4/7-Byte UID is used.

10 Test Connection with Hercules
Hercules Setup Utility can be used to test the terminals behavior.
•Set the terminal in Client mode (skip this step if the terminal is already in client mode)
•Select TCP Server and enter the Terminals port number
•Click on Listen
•The terminal will connect automatically as seen in the connection status
•After presenting a card, the message will be displayed in the Received data window
•Enter the response message and send to the terminal. The device ID must be the same in the
received and sent data
•As the TCP connection is open, we can send commands directly to the terminal
Use the TCP Client tab if the terminal is configured as a server.
