WAF - High Power
RFC-RF-41
Installation Guide
The WAF (Wireless Automated Fueling) Unit is a transmitter that in conjunction
with the Vehicle Identification Sox (VIS) enables to identify the vehicle automatically
on the fuel Island. The single antenna RF module is connected to the antenna via
short COAX cable and to the CPU via RS-485 with a Separate ground connection
General description
The EUT is a Medium power 24dBm Output FHSS transceiver module operating at
the ISM frequency band 902-928 Mhz And utilize a master transmitter in a masterslave network.
The modem has an External antenna.
The modem is being used as a master in a station controller. The environment is a fuel
station.

Technical description
The device is a complete RF transceiver, it has its own reference oscillator and
permanently attached antenna. The only connectors are RJ-45 for data signal and
power feed and Grounding terminal. The data inputs are buffered.
The EUT operates with DC voltage of 9 to 30 Vdc. Current consumption is maximum
150 mA.
When the transceiver transmits a frame with different frequency every 380 mSEC, the
frequency is changed on a predetermined, pseudo random pattern. There are 51
different frequencies. The occupancy time on any frequency is 380 mSEC. The cycle
period is 51*380msec which is 19.38 second.
The transmission frame is divided to 19 time slots 20 mSEC each. The second and the
last slot are not used. The first time slot is used for one beacon transmission of 5.8
mSEC and a command of up to 7 mSEC. The other active time slots contain only the
beacon and leave the slot open for the response. This means that the maximum Tx on
time is 17*5.8 + 7 = 106 mSEC, which is 28% duty cycle.
The user may send data to the module only during the last time slot. The module
signals this time slot by outputting low level at the TXFLAG output.
The data is transferred to or from the transceiver by serial communication with baud
rate of 28800.
The transceiver includes a CPU. The CPU is a buffer for the data inputs. It receives
the data from the user at any time and sends it at the correct time slot to the
transceiver.
The module transceiver has its own RF shield and cable dipole antenna without
connector. The output power is constant 24 dBm.

FCC Compliance Statement:
This device has been tested and found to comply with the limits for a Class B digital
device, pursuant to FCC Part 15, sub-part C of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in residential installations.
This equipment generates uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference
to radio and television reception.
However, there is no guarantee that interference will not occur in a particular
installation.
If this device does cause such interference, which can be verified by turning the
device off and on, the user is encouraged to eliminate the interference by one or more
of the following measures:
– Re-orient or re-locate the receiving antenna.
– Increase the distance between the device and the receiver.
– Connect the device to an outlet on a circuit different from the one that supplies
power to the receiver.
– Consult the dealer or an experienced radio/TV technician.
WARNING! Changes or modifications to this unit not expressly approved by the
party responsible for compliance could void the user’s authority to operate the
equipment.
This equipment complies with the FCC RF radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a
minimum distance of 20cm between the radiator and any part of human body.
