3.0 CONFIGURATION
The Model 1180 uses a set of eight external DIP switches that allow configuration to a wide range of applications. Because all eight switches are in one externally accessible DIP package, there is no need to open the Model 1180’s case for configuration. The switches allow you to control data rates and clocking methods. Figures 1, 2 and 3 summarize the switch locations, positions and functions.

3.1 DETAILED SWITCH SETTINGS
This section provides detailed information about the function of each DIP switch and lists all possible settings. Use this section as configuration guide for applications where the Model 1180’s default would not provide correct results.
Switch 1: Reserved for Future Use
Switches 2 though 5: Data Rate (Sync. Mode)
Switches 2 through 5 determine two configuration parameters: synchronous or asynchronous data rate and the mode of synchronization (Sync. Mode) between two Model 1180s. The “Sync. Mode” setting (active in both asynchronous and synchronous operating modes) defines the packet length of the data stream between the two Model 1180s.
Simply put, the “2X” setting doubles the space between data packets when compared with the “1X” setting. A Sync. Mode setting of
“2X”acilitatesf communication distances up to 5 Km. A Sync. Mode setting of “1X” limits communication distances to 2.5 Km. The following table shows every possible data rate/Sync. Mode switch setting for the Model 1180.
