4.11 Interface Reconfiguration

Figure 4-18 illustrates how the interface circuit board fits into the larger main
modem board opening.
A header-type connector is provided to connect the two circuit boards together.
The interface board may be removed by loosening the two retaining screws and
nuts, then pulling the board outward from its connector.
Once a replacement board is in position, the two flanged lock nuts and screws are
secured with built-in flat washers above and below the board junctures.
It may be desirable to select a new data rate at this time using the front panel
switches as outlined in Chapter 3 of this manual.
