Installation Manual Description of the radio telemetry equipment
Description of the radio telemetry equipment Remote Eagle Module (REM) The REM connects to the Left or Right Transverse connector of an LAUX, or a 408UL control module or another REM. It interfaces a radio cell with a wireline telemetry section or with the CM408 or 408XL. It is used to control the digitizer units (SU6-R) in a radio cell and retrieve the seismic data from it.
Description of the radio telemetry equipment l0 W RF output~ power (rain); One REM in each RF cell (1 retrieve frequency); Up to six REMs can be used on one antenna; Maximum number of REMs in a network: 16; Typical range: 16 to 24 km (10 to 15 miles). The REM has a built-in signal strength meter used to monitor the RF Spectrum on the HCI workstation, and an output for connection to an external spectrum analyzer with a finer resolution.
Installation Manual Description of the radio telemetry equipment SU6-R The SU6-R is a six-channel field digitizer unit used in radio telemetry cells. It uses a radio link to communicate with a REM. All the SU6-Rs are completely independent and can coyer any type of field. In the event of obstruction along an RF radio path to the REM, a simple wire telemetry link can be used in place of the RF link.
Installation Manual Description of the radio telemetry equipment FDPA (Field Deployment aid) The FDPA is a small hand-held terminal that allows you to program, monitor and test certain aspects of the setup for an SU6-R. Typically the checks are performed at the time of physical SU6-R deployment in order to speed up deployment. The FDPA activates the SU6-Rs power-up self-test, can evaluate cable leakage and continuity tests, and assign the SU6-R address and SU6-R wire-line function.
Radio telemetry equipment (REM, SU6-R) Description of the radio telemetry equipment Battery charger It's a portable 8-hour charger designed to simultaneously charge 1 to 36 SU6-Rs. There are 6 charging cables. Each cable can charge up to six SU6-R units. LED circuits provide a visual indication of the charging process. Since each of the chargers is fully automatic, a battery can be connected to or disconnected from the charger independently of the others.
Radio telemetry equipment (REM, SU6-R) Connecting REMs Connecting REMs Minimum distance requirements In order not to overload the receiving stage in REMs and SU6-Rs, the following minimum distances are required: between REM and SU6-R: between REMs: between SU6-Rs: 100 m (300 ft); 300 m (1000 ft); 100 m (300 ft). These are approximate values, depending on the type and direction of the antenna and on various RF transmission parameters.
Installation Manual Cab-mount aerial installation Compressor setting For in-depth information, please refer to the manufacturer's document. Before using the air compressor on the field, the primary pressure switch sensing the receiver should be set according to the motor maximum compression capacity in order not to damage the motor. For a 50 PSI maximum compression capacity given as an example, the motor should start when the receiver pressure falls around 25 PSI and stop at 50.
Radio telemetry equipment (REM, SU6-R) Cab-mount aerial installation Rotator Setting The information given below concerns the AR-40 Antenna Rotator manufactured by Hy-Gain. For in-depth description, the user should refer to the manufacturer documents. Pre-Installation Check and Calibration. Before mounting the rotator unit on the considered mast or tower, check the operation with the control unit and cable. Strip all conductors at both ends of the cable and attach to the terminals.
Installation Manual Cab-mount aerial installation Leave both rotators in the 'NORTH' position for the mast and antennae array indexing and put a pen mark on upper and lower parts of each rotator so that the 'NORTH' position is dearly visible. Typical setting of the cab-mount antenna After installing the antenna (see Cab-mount aerial installation on page 8-14), a variety of adjustments can be considered with a view to coveting your specific spread performance.
Radio telemetry equipment (REM, SU6-R) S U6-R deployment SU6-R deployment Overview Controlled by operational commands on the transmit frequency from the Remote Eagle Module (REM), the microprocessor in the SU6-R can receive, convert, stack, store and transmit (on the REM receive frequency) seismic data to be processed by the CM408 or CMXL. With up to six REMs in the master/slave configuration, the data can be retrieved simultaneously from all. SU6Rs on up to six frequencies.
