SERIES RP-RF100 RADIO COMMUNICATION MODULES

Series RP-RF100 communications modules can be supplied, optionally, into all series RP-1500 beacons, allowing serial radio communications with the beacons as far as up to 1.000 metres with direct antenna view between modules. These modules can replace expensive and/or difficult wiring, emulating a serial communications channel as if there was a wiring link (transparent serial radio link).

As each of the series RP-1500 beacon has two serial ports, each one can be added up to TWO RP-RF100 modules, but each one should operate in a different channel to avoid interference.

Radio communication link is stabilised under 433 MHz or 902 MHz Band, license free under the actual power emissions of the modules.

Series RP-RF100 modules can be supplied in two versions: one for installing INSIDE the beacon's casing and another for external installation (for the communications of the beacons with other hardware, like terminal RP-2000 for instance). The main function these modules were designed for, is enabling a communications link between external earth fixed beacons and on-board equipment, so the beacons can communicate with any serial internal device inside the train. For instance, the system may also want to know, further than the physical train number read by the beacon, the "logical" number of the train (in Spain, ALWAYS keyed in by the driver before departure). Thus, serial radio link between on board terminal and the beacon can be done!. Of course, any other communication with any other on-board device can be also considered.

Radio communication can be bi-directional, so communications can be started by the beacon or by the external equipment (terminal RP-2000, for instance).

Common Features

Common features to all series RP-RF100 are:

Operating frequency: 433 MHz or 902 MHz

Number of channels inside the band: 10

Transmission speed of radio link: 9,6 Kbits/sec (transparent) ó 12,5 Kbits/sec (buffered mode).

Modulation / demodulation method: F.S.K. (Frequency Shift Keying)

Reception sensibility: -95 dBm over 50 Ohms.

Power emission: 10 mw. (433 MHz.) or 50 mv. at 3 metres (902 MHz.)

Transmission speed on the serial wired port: 1.200 a 38.200 baud.

Communications range: up to 1.000 open field and direct antenna vision.

Following you can find the different RP-RF100 models and its main features:

RP-RF100-XXX Models

This model is the internal version, that is installed INSIDE the series RP-1500 beacons. Compact and low power consumption. Can be supplied in both 433 MHz. (RP-RF100-433) and 902 MHz. (RP-RF100-902) bands. As main features:

Power consumption: 60 mA in emission, and 30 mA in reception, 100 m A in stand-by.

Helicoidal Antenna of 68 mm. (going out through the beacon casing).

NOT sold separately (factory installed).

RP-RF110-XXX Models

This is the external version, for connecting any RS232 serial device with the series RP-1500 beacons or to any other RP-RF100 module. Can be supplied in both 433 MHz. (RP-RF110-433) and 902 MHz. (RP-RF110-902) band. Main features are:

Aluminium casing with 68 mm. helicoidal antenna incorporated.

External DB9 connector for RS232 cabling to the serial control device.

Power consumption: 60 mA to 90 mA in emission / reception.

Power supply: external, from 8 to 30 VDC, protection IEC 801 – 4,2 Kv.

Dimensions (mm.): 89 x 64 x 24 mm. Antenna: 68 mm.

This model is available separately, if it wants to be installed for controlling any other serial device. Even they can be also used for beacons radio link, if mounted externally and even at some distance from the beacon.

External power supply is NOT included.
