RipEX2 is a radio modem platform renowned for overall data throughput in any real-time environment. RipEX2 radio modems are native IP devices, Software Defined with Linux OS that have been designed with attention to detail, performance and quality.
RipEX2 is built into a rugged die-cast aluminium casing that allows for multiple installation possibilities, see Section 4.1, “Mounting”.
All connectors are located on the front panel. The upper side features an LED panel. The RESET button is located in an opening in the bottom side.
An antenna can be connected to RipEX2 via TNC female 50Ω connector.
RipEX2 is equipped with two connectors. The Tx/Rx connector will be used for common transmitting and receiving single antenna installation (even with different Rx and Tx frequencies).
Both Rx and Tx/Rx connectors for split installation (two antennas or duplex operation with duplexer) – Rx for receiving and Tx/Rx for transmitting.
RipEX2 radio modem 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 RipEX2. 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. RipEX2 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 RipEX2. RipEX2 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. RACOM offers all mentioned types of SFP modules, tested to be RipEX2 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 RACOM and are guaranteed to function with RipEX2 units. It is possible to use any other SFP module, but RACOM cannot guarantee they will be completely compatible with RipEX2 units.
RipEX2 provides serial interface COM terminated by DSUB9F connectors. It can be configured as RS232 or RS485.
RS232 of RipEX2 is a hard-wired DCE (Data Communication Equipment) device. Equipment
connected to the serial port of RipEX2 unit should be DTE (Data Terminal Equipment) and a
straight-through cable should be used. If a DCE device is connected to the serial port of
RipEX2, a null modem adapter or cross cable has to be used.
RS485 of RipEX2 is not galvanic isolated and it is not terminated.

RipEX2 keeps pin 6 DSR at the level of 1 by RS232 standard permanently.
RipEX2 uses USB 3.0, Host A interface. USB interface is wired as standard:
Tab. 1.4: USB A Pinout Cable Assembly
The USB interface is designed for the connection to an external ETH/USB adapter or a Wifi adapter. They are optional accessories to RipEX2, for more details see Section 3.3, “Connecting RipEX2 to a programming PC”. The adapters are used for service access to web configuration interface of RipEX2 unit.
The USB interface can also be used for an external flash disc connection, which has been specifically designed to simplify complex maintenance tasks, so that these tasks can be performed by unqualified personnel in the field by simple plugging-in an USB stick and waiting until a LED flashes.
The USB connector also provides power supply (5 V / 0.5 A). It can be used to temporarily power a connected device, for instance a telephone. The USB connector should not be used as permanent source of power supply.
AUX SMA female 50 Ohm connector is used for several purposes according to HW variant.
Standard basic model – the AUX is used as an synchronization signal input.
Input frequency range 1 Hz (PPS) – 25 MHz
Input signal level >200 mVp-p @ 220R, up to 5V TTL levels
RipEX2 can be equipped with an internal GPS. The GPS module is used for time synchronization of the NTP server inside RipEX2. In this case the AUX connector serves for connecting the GPS antenna:

Adaptive mode of receiver operation
Cognitive function of receiving mode selection is implemented in RipEX2. When exposed in a radio environment where strong interfering signals (stronger than -45 dBm) are present, RipEX2 senses them and adaptively increases its resistance to interference (and lowers its sensitivity by 3 dB). When interference holds, RipEX2 stays in high resistance mode of receiver operation and signals this state by turning the yellow RX LED on. Once the interfering signals fade away, RipEX2 automatically returns to its high sensitivity mode of receiver operation.
RipEX2 radio modem has been designed to have minimum possible number of hardware variants. Different HW models are determined by frequency, internal GPS and separate connectors for RX and TX antennas.
