Figure 3.4 JW3 Pin Assignments and Settings
Use the worksheet in appendix B to document the selected jumper setting of
jumper JW3. Documenting your selection provides others with information
necessary to integrate the module with their SLC 500 fixed or modular controllers.
Setting Jumper JW4
Use jumper JW4 to select one of the following configurations for the module ports:
•
PRT1 Port – Program port with default communication settings
PRT2 Port – ASCII interface port
DH485 Port – Run time DH485 operation only
•
PRT1 Port – ASCII interface port
PRT2 Port – ASCII interface port
DH485 Port – Program port with DH485 protocol
•
PRT1 Port – Program port with programmed communication settings
PRT2 Port – ASCII interface port
DH485 Port – Run time DH485 operation only
•
