Set the Module’s Functionality
Setting the module’s mode depends on which method you want to use to configure
the module. You can configure the module using an ASCII terminal or backplane
communication.
Configure the Module with an ASCII Terminal
Configure the interface module with an ASCII terminal only when the JW4 jumper
is in Configuration mode. Place the module in the Configuration mode that
corresponds to the functionality you chose for the interface module, as shown
below.
Refer to page 7 for location of jumper JW4.
Figure 5 JW4 Jumper Set for Configuration Mode
Configure the Module via the Backplane
Read and write configuration data through the backplane with series B interface
modules, and then only when the JW4 jumper is in the vertical Run mode position.
Place the module in vertical Run mode as shown below.
Refer to page 7 for location of jumper JW4.
