Figure 3-2. Sample DIP-Shunt Setting.

Figure 3-2 shows the DIP-shunt settings used for an application like the one illustrated in Figure 3-3a.

NOTE

The filled-in rectangles in Figure 3-2 indicate the jumpers that contain a DIP-shunt.

CAUTION

Never set both ports the same: the clocks will not operate correctly. If two DTEs are connected through the Converter, a modem eliminator is required in order to avoid setting both ports the same. If two DCEs are connected together, a cross-over cable is required.
