MODULAR FIBER CAMPUS DRIVER, MFCD PLUS

3. Configuration

Both Models ME621A and ME620A use a mini DIP-switch package that allows
configuration to a wide range of applications. These switches are located on the
bottom side of the PC board (see Figure 3-1). Because all eight switches are
externally accessible, you don't have to open the case to configure the unit.

DIP switches.
Configuration Switch "S1"
The switches shown in Figure 3-2 and on DIP switch S1 are used to set the async or
sync data rates, LAL and DL diagnostic functions, and the clock-mode setting. The
default settings for DIP switch S1 are shown in Table 3-1. Following the table are
detailed descriptions for each switch.
