19. Set DIP switches SW4-1 through SW4-8 for the desired amount of receive attenuation.
Each section of SW4 controls a specific amount of attenuation:
SW4-1 0.1 dB
SW4-2 0.2 dB
SW4-3 0.4 dB
SW4-4 0.8 dB
SW4-5 1.5 dB
SW4-6 3.0 dB
SW4-7 6.0 dB
SW4-8 12.0 dB
The switch settings are cumulative. For example, to set the attenuation to 19.0 dB,
set the switches as follows:
Section Value Setting Set Value
SW4-1 0.1 dB OFF 0.0
SW4-2 0.2 dB ON 0.2
SW4-3 0.4 dB OFF 0.0
SW4-4 0.8 dB ON 0.8
SW4-5 1.5 dB OFF 0.0
SW4-6 3.0 dB OFF 0.0
SW4-7 6.0 dB ON 6.0
SW4-8 12.0 dB ON 12.0
TOTAL 19.0
To set the attenuation to 7.6 dB, set the switches as follows:
Section Value Setting Set Value
SW4-1 0.1 dB ON 0.1
SW4-2 0.2 dB OFF 0.0
SW4-3 0.4 dB OFF 0.0
SW4-4 0.8 dB OFF 0.0
SW4-5 1.5 dB ON 1.5
SW4-6 3.0 dB OFF 0.0
SW4-7 6.0 dB ON 6.0
SW4-8 12.0 dB OFF 0.0
