2.2.1. Antenna

Antenna connectors

Fig. 2.6: Antenna connectors


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.

[Warning]Warning

RipEX2 radio modem may be damaged when operated without an antenna or a dummy load.

2.2.2. Power and Control

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.

2.2.3. ETH1 – ETH4

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.

2.2.4. ETH5 (SFP)

SFP slot

Fig. 2.9: SFP slot


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.

[Important]Important

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.

2.2.5. COM

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.

Expansion board ‘C’ (2 x RS232)

The 2nd and 3rd COM ports are available when the Expansion board ‘C’ (2 x RS232) is installed. In such a case: The DI/DO connector is used as a connector for COM2 and COM3.

COM2 and COM3 parameters:

  • COM2: RS232 – 5 pin (RxD, TxD, GND, RTS, CTS) 300 b/s to 2 Mb/s

  • COM3: RS232 -3 pin (RxD, TxD, GND) 2.4 kb/s to 921.6 kb/s

    If the RipEX2 unit is installed in the RipEX2-HS (Hot Standby chassis), the DI/DO interface is dedicated for the Hot Standby operation.

2.2.6. USB

RipEX2 uses USB 3.0, Host A interface. USB interface is wired as standard:

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 ???. The adapters are used for service access to web configuration interface of RipEX2 unit.

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.

2.2.7. AUX

AUX connector SMA

Fig. 2.10: AUX connector SMA


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:

  • active antenna

  • 3.3 VDC supply

Alarm

An Alarm is triggered by any event with severity Error or higher (see Section 8.2, “Events”).

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.
