Rockwell Automation 1747-KE,D17476.12 DH-485/RS-232C Interface Module - Manual (Page 41)

Publication 1747-UM005B-EN-P - March 2006
Installation and System Configuration 4-3
module configuration ID equivalent to the module configuration ID of
the series A module you are replacing (4209).
As you work through the remainder of this manual, follow the
instructions for series A functionality (horizontal placement of the JW4
jumper).
Series B Functionality
The series B module functions identical to the series A module, but
has these additional features.
• Real Time Clock (RTC)
• Backplane configuration
• SLC processor reset of the interface module
If you want to use the added features of the series B interface module,
follow the directions given for series B functionality (vertical
placement of the JW4 jumper) as you work through the remainder of
this manual.
IMPORTANT
The increased functionality of the series B interface
module (for example, the Real Time Clock,
backplane configuration, and SLC processor reset of
the interface module) is not available with the series
A functionality.
IMPORTANT
You will be required to change the module
configuration ID assigned in your processor. The
vertical placement of the JW4 jumper gives your
module a configuration ID that differs from the
configuration ID of your series A interface module.
The procedure for changing the module
configuration ID is explained later in this chapter.
