Page 27: Mounting
4.1. Mounting 4.1.1. DIN rail mounting M!DGE3 cellular modem is directly mounted to the DIN rail by a holder (which comes with the modem). Fig. 4.1: DIN rail Using this mounting M!DGE3 can be mounted in different angles (by 90° clockwise/counter clockwise).
Page 28 Installation For edged mounting to the DIN rail, Edge-bracket (optional accessory) is used. Use solely the M4×5 mm screws that are supplied. Fig. 4.2: Edged mounting to DIN rail M!DGE3 Cellular Router – © RACOM s.r.o.
Page 29 4.1.2. Flat mounting For flat mounting directly to the support you must use the Flat bracket (an optional accessory). Use solely the M4×5 mm screws that are supplied. Fig. 4.3: Flat mounting using Flat bracket © RACOM s.r.o. – M!DGE3 Cellular Router...
Page 30: Antenna Installation
Use 50 Ω impedance cables only. The shorter the feed line, the better. If M!DGE3 is installed close to antenna, the data cable can be replaced by an Ethernet cable for other protocols utilizing the serial port, see Section 7.1.3, “Terminal servers”.
Page 31: Connectors
M!DGE3 may be powered from any well-filtered 10 to 50 VDC power source. The supply must be capable of providing the required input for the projected RF output. To avoid radio channel interference, the power supply must meet all relevant EMC standards.
Page 32: M!Dge3 In Detail
5.1.1. Detailed Description Generally, a Terminal server (also referred to as Serial server) enables connection of devices with a serial interface to a M!DGE3 over the local area network (LAN). It is a virtual substitute for the devices used as serial-to-TCP(UDP) converters.
Page 33: Web Interface
(via LAN) or a high-speed WAN (e.g. Internet). The M!DGE3 which you are logged-in to in this way is called Local. Then you can manage any remote M!DGE3 in the network over-the-air in a throughput-saving way: all the static data (e.g. Web page graphic objects) is downloaded from the Local M!DGE3 and only information specific to the remote unit is transferred over the Radio channel.
Page 34 Note Web interface for M!DGE3 is identical to RipEX 2. The login page informs you about the Unit name and IP address of the M!DGE3 unit you are trying to log in. The login page allows changing of the language of the whole web interface (English language is default).
Page 35: Supported Web Browsers
6.2. Changes to commit M!DGE3 is capable of remembering changes, which were done in its configuration and collecting them in a Changes to commit "basket". All changes of configuration parameters are highlighted by different color.
Page 36 • Return to configuration - return to the last changed value. • Reset changes - all changes will be reset back to their previously set value (not default). • Send configuration - Apply (Save to radio unit) all the changes. M!DGE3 Cellular Router – © RACOM s.r.o.
Page 37: Notifications
Web interface 6.3. Notifications With M!DGE3 new way of showing important system events to the user is introduced. It is called Noti- fication Centre and is used consistently throughout the interface. Notification Centre is located on the top right corner of the interface. It exists in two forms: active notification display and full Notification Center.
Page 38: User Menu
It is strongly recommended to change the default password. 6.5. Remote access M!DGE3 unit management is designed to work smoothly even when the unit under configuration is connected via relatively slow radio channel. In case of locally connected unit - direct configuration of the unit (accessing the unit IP address directly from the web browser) works fine.
Page 39 Remote access can be activated via click on the Remote access button. The connection to remote radio proceeds... The IP address of the actually connected M!DGE3 unit is displayed as part of the Remote access button. All the configuration settings are remotely available using standard web interface. Some of the Diagnostic features are available via local connection only.

7.1. Interfaces 7.1.1. Ethernet M!DGE3 provides 5 physical Ethernet ports ETH1, ETH2, ETH3, ETH4 and ETH5. ETH1 - ETH4 ports are metallic. ETH5 port is a SFP port. There is a possibility to define an Ethernet bridge - a logical Network interface - by bridging (joining) together multiple physical Ethernet interfaces.
Page 43 Each Network interface can have attached one on more VLANs with one or more Subnets. Enable / Disable Enables / disables VLAN. VLAN ID Number {0 – 4094 }, default = 1 Specifies the VLAN ID according to IEEE 802.1Q © RACOM s.r.o. – M!DGE3 Cellular Router...

Defines the speed and half / full duplex traffic. Note When several bridges are interconnected in the network, it is appropriate to switch-on Spanning Tree Protocol (ADVANCED-Interfaces-Ethernet-STP) to prevent bridge loops and build a loop- free logical topology. M!DGE3 Cellular Router – © RACOM s.r.o.
Page 45: Com
Settings 7.1.2. COM Data incoming to the M!DGE3 unit from the COM port are received by the Protocol module. The Protocol module behavior depends on the Protocol selected. In case of Transparent protocol (available in Bridge mode only), it is transparently transmitted to the M!DGE3 network and send out through all COM ports with Transparent protocol selected.
Page 46 This parameter defines the maximum gap (in milliseconds) in the received data stream. If the gap exceeds the value set, the link is considered idle, the received frame is closed and forwarded to the network. MRU [B] Number {1 – 2047}, default = 1500 M!DGE3 Cellular Router – © RACOM s.r.o.
Page 47: Common Protocol Parameters
RTS/CTS (Request To Send / Clear To Send) hardware flow control (handshake) between the DTE (Data Terminal Equipment) and M!DGE3 (DCE - Data Communications Equipment) can be enabled in order to pause and resume the transmission of data. If RX buffer of M!DGE3 is full, the CTS goes down.
Page 48 UDP ports for COM or Terminal servers can be used or UDP port can be set manually. If the des- tination IP address belongs to a M!DGE3 and the UDP port is not assigned to COM or to a Terminal server or to any other special SW module running in the destination M!DGE3, the packet is discarded.
Page 49 The Address translation is defined in a table. There are no limitations such as when the "Mask" translation is used. If there are more SCADA units connected via the RS485 interface, their multiple "Protocol addresses" are translated to the same IP address and UDP port pair. © RACOM s.r.o. – M!DGE3 Cellular Router...
Page 50: Individual Protocol Parameters
The None protocol switches the COM port off. All incoming data will be thrown away, No data will be send into the COM interface. 7.1.2.3.2. Transparent protocol Operates in Bridge mode only. All the traffic is bridged transparently to M!DGE3 network (see ??? for details). 7.1.2.3.3. Async link Async link creates an asynchronous link between two COM ports on different M!DGE3 units.

MARS-A was widely used by legacy RACOM radio modems in the MORSE system from the year 1999. The new implementation of this protocol in M!DGE3 is limited to the parts of the complex protocol which can be used together with modern packet type of radio routers: USER DATA (0x09) from router to the serial interface (e.g.
Page 56: Modbus Rtu
7.1.2.3.9. Modbus RTU Modbus RTU is a serial polling-type communication protocol used by Master-Slave application. When M!DGE3 radio network run in Router mode, more Modbus Masters can be used within one Radio network and one Slave can be polled by more Masters.

Page 64: Uni
Settings 7.1.2.3.14. UNI UNI is the 'Universal' protocol utility designed for M!DGE3. It is supposed to be used when the required application protocol is not available in M!DGE3 and the network communication is using addressed mode (which is a typical scenario). The key prerequisite is: messages generated by the Master applic- ation device must always contain the respective Slave address and the address position, relative to the beginning of the message (packet, frame), is always the same (Address position).
Page 65: Terminal Servers
TCP messages and processed like it comes from a COM port. When data reaches the destination M!DGE3, it can be transferred to the RTU either via a serial interface or via TCP (UDP), using the Terminal server again.
