Installation

SW1-5 − Receiver Dynamic Range

SW1-5 ON = −10 to −43 dBm

OFF = +3 to −30 dBm

For a low receive signal level, set SW1-5 to ON (−43 dBm ). For short distances or to select a strong receive signal, set SW1-5 to OFF.

SW1-6 and SW1-7 − Cable Equalizer (Fast-Poll Mode Only)

SW1-6 ON = Enable TX Cable Equalizer

OFF = Disable TX Cable Equalizer

SW1-7 ON = Enable RX Cable Equalizer

OFF = Disable RX Cable Equalizer

To improve or extend the modem’s polling performance, use the fixed Compromise Cable Equalizer when polling on long metallic circuits. The cable equalizer is active only when the modem is in fast-poll mode (SW3-1 set to OFF).

SW1-8 − Anti-streaming

SW1-8 ON = Anti-streaming active

OFF = Anti-stream inactive

Typically, anti-streaming is used in multi-point applications to prevent a malfunctioning slave modem from occupying the line indefinitely. When anti-streaming is active, the modem can transmit data for a maximum of 27 seconds before the transmitter turns off automatically. The modem then looks for an ON-to-OFF Request To Send (RTS) transition before proceeding with normal operation. Anti-streaming can be selected in either high-speed or low-speed mode.
