    FCC and IC regulations; maximum power output from the antenna must not exceed 36 dBm. The SEL-3031 can transmit as much as 1 W or 30 dBm from the antenna port. If the calculated EIRP exceeds 36 dBm then you must reduce the power transmitted by the radio by reducing the transmit power setting TXPWR (see the TXPWR description in Radio Settings on page 4.12 for more information).

    When constant interference is present in a particular frequency zone, ➤ it may be necessary to “lock out” that zone from the SEL-3031 hopping pattern.

    The SEL-3031 has a better way to solve this problem by allowing collocated radios to synchronize their transmit and receive time slots and hop at exactly the same time. This will prevent the large signal difference from occurring and the collocated antennas can be placed within 2.4–3 m (8–10 ft) of each other.

    Easily check this by looking at the master SEL-3031 Tx and Rx LEDs on Port 1. If the Tx LED illuminates, and the Rx LED illuminates shortly after, the link is up and working. If you only see the Tx LED illuminate and not the Rx LED illuminate you either have a problem with the settings in the radio, settings problem on the SEL-651R, or you are using the wrong cable.

    A good radio link should have 15 dBm of margin to account for environmental conditions and signal fade. The SEL-3031 receiver is rated down to –97 dBm or –104 dBm with ARQ on. If you observe a fade margin of 15 dBm or greater then you are receiving a strong signal.

    SEL-3044 Encryption Card Overview The SEL-3044 Encryption Card is a standalone card that can be added to the SEL-3031 to encrypt the radio data being sent between SEL-3031 radio links. The SEL-3044 can be ordered at time of purchase or added as an upgrade. The SEL-3044 requires one setting to provide a very strong level of encryption over the radio link.

    The Advanced Encryption Standard (AES) algorithm with a key length of 256 bits is implemented in the SEL-3044. This algorithm is a secure means of encrypting data. The AES algorithm and key length provide proven resistance to modern cryptanalysis. SEL-3031 Instruction Manual Date Code 20181001...
