M!DGE3 is a cellular router platform designed for any real-time environment. M!DGE3 cellular routers are native IP devices, with Linux OS that have been designed with attention to detail, performance and quality.
M!DGE3 is built into a rugged metal casing that allows for multiple installation possibilities, see Section 4.3, “Mounting”.
All connectors are located on the front and bottom panel. The front panel contains even LEDs. The HW button is located on the front panel as well (close to the upper edge).
An antenna can be connected to M!DGE3 via SMA female 50 Ω connector.
M!DGE3 is equipped with two connectors. The ANT1 connector will be used for common transmitting and receiving. The ANT2 connector will be used as a Rx diversity connector.
![[Note]](/images/radost/images/icons/note.png){kind=icon} | Note |
|---|---|
For optimal LTE connection, using both antennas (Rx diversity) is recommended. If only one antenna is used, attach it to the ANT1 connector. |
![[Warning]](/images/radost/images/icons/warning.png){kind=icon} | Warning |
|---|---|
M!DGE3 cellular router may be damaged when operated without an antenna or a dummy load. |
This rugged connector connects to a power supply and it contains control signals. A plug with screw-terminals and retaining screws for power and control connector is supplied with each M!DGE3. It is Tyco 7 pin terminal block plug, part No. 1776192-7, contact pitch 3.81 mm. The connector is designed for electric wires with a cross section of 0.5 to 1.5 mm2. Strip the wire leads to 6 mm (1/4 inch). Isolated cables should receive PKC 108 or less end sleeves before they are inserted in the clip. Insert the cables in the wire ports, tightening securely.

Standard RJ45 connectors for Ethernet connection. M!DGE3 has 10/100/1000Base-T Auto MDI/MDIX interfaces so it can connect to 10 Mb/s, 100 Mb/s or 1000 Mb/s Ethernet network. The speed can be selected manually or recognized automatically by M!DGE3. M!DGE3 is provided with Auto MDI/MDIX function which allows it to connect over both standard and cross cables, adapting itself automatically.

ETH5 is a standard SFP slot for 10/100/1000 Mb/s Ethernet SFP modules, user exchangeable
with maximal power consumption 1.25 W. Both fibre optic and metallic Ethernet SFP modules
are supported. For optical both single and dual mode fibre optics Ethernet modules (= 2 or 1
fibers) can be used. CSFP modules are not supported.
offers all
mentioned types of SFP modules, tested to be M!DGE3 compatible as a standard
accessory.
The SFP status LED is located just next to the slot. It is controlled by SFP module. Its function is specific for each SFP module. The typical behavior is an indication the received signal from the fibre optic or metallic link to be within operational range.

|---|---|
It is strongly recommended to use a high quality SFP module with industry temperature range. The SFP modules listed in Accessories are thoroughly tested by and are guaranteed to function with M!DGE3 units. It is possible to use any other SFP module, but cannot guarantee they will be completely compatible with M!DGE3 units. |
M!DGE3 provides serial interface COM terminated by 5 pin terminal connector which is supplied with each M!DGE3 unit. It can be configured as RS232 or RS485. It is Tyco 5 pin terminal block plug, part No. 1776192-5, contact pitch 3.81 mm. The connector is designed for electric wires with a cross section of 0.5 to 1.5 mm2. Strip the wire leads to 6 mm (1/4 inch). Isolated cables should receive PKC 108 or less end sleeves before they are inserted in the clip. Insert the cables in the wire ports, tightening securely.
RS232 of M!DGE3 is a hard-wired DCE (Data Communication Equipment) device. Equipment connected to the serial port of M!DGE3 unit should be DTE (Data Terminal Equipment).
RS485 of M!DGE3 is not galvanic isolated and it is not terminated.

M!DGE3 cellular router can be delivered with additional (optional) second cellular module, GPS extension or COM extension. In case of Cellular or GPS it comes with two additional SMA connectors installed on the bottom panel (EXT1, EXT2). Activity of any extension module is signalized on M!DGE3’s front panel (EXT LED).
It is recommended to use both antennas (Rx diversity) for the LTE connection. In case of using only one antenna, attach it to the EXT1 connector. The EXT1 connector is used for both transmitting and receiving, or for single-antenna setups. The EXT2 connector is specifically for Rx diversity.
When the 2nd cellular module is used, LED behavior of this extension is signalized by Green / Orange / Red LED
Permanently lit – Connected to the cellular network (color signalize signal strength)
Flashing in 1 sec interval – Connecting into the cellular network
M!DGE3 cellular router will be equipped with the GPS receiver with time pulse output. EXT1 connector is used for connection of the active GPS antenna, EXT2 connector is used for the precise time pulse output.
