DM5210 analog input module 1-3 RTD Embedded Technologies, Inc.
Factory-Configured Switch and Jumper Settings
Table 1-1 lists the factory settings of the user-configurable jumpers and switch on the 210/5210. Figure 1-1
shows the module layout and the locations of the factory-set jumpers. The following paragraphs explain how to
change the factory settings. Pay special attention to the setting of S1, the base address switch, to avoid address
contention when you first use your module in your system.
