The internal jumpers mounted on the Model 2703’s PC board

(labeled LK1 - LK7) are used to configure the 75 ohm or 120 ohm net- work link parameters. Figure 4 (above) shows the location of the Model 2703’s jumpers on the internal PC board.

The table below shows the factory default jumper settings. Following the table are descriptions for each jumper.

NOTE: One combination of jumper settings is required for 75 ohm operation, and another combination is required for 120 ohm opera- tion. The Model 2703 is factory configured for 75 ohm operation.)

Jumper LK1: 75 Ohm Transmit Shield-to-Ground Connection

This setting determines whether the shield of the 75 Ohm (coax) transmit cable is connected to earth ground. This connection must be made when operating in 75 Ohm (unbalanced) mode. Conversely, this connection must not be made when operating in 120 Ohm (balanced) mode.

Jumper LK5: Configuration Auto-Sense

This setting determines whether the host can automatically sense the configuration of the Applique. The operation of the Applique is not affected by this jumper setting. Auto-sense should be enabled when operating in 75 Ohm (unbalanced) mode. Current interface standards do not list this feature for 120 Ohm (balanced) mode.
