1. MODE AND FUNCTION
The IF-2550 is a unit that integrates the functions of the current interface units IF-1001, IF-2300, IF-
2500, IF-2503, and the distributor MD-550. Functionality of each model can be activated by setting
the appropriate DIP switches. DIP switch settings are outlined in Chapter 8.
The table below shows the comparison of each mode and function.
