CHAPTER 4 Configuring the Serial Converter This chapter provides information about configuring the Serial Converter. For a list of parameters, refer to Appendix B, Serial Converter Parameters. 4.1 Configuration Tools The Serial Converter stores parameters and other information in its own non-volatile storage (NVS). You must, therefore, access the Serial Converter to view and edit its parameters. Table 4.1 lists tools that you can use to access the Serial Converter and edit its parameters. Table 4.
This section is designed to help users start using VS Utilities. If you are unsure how to complete a step, refer to the online help (select Help > Help Topics). Use the following procedure to configure the Serial Converter using VS Utilities software: Step 1. Select Explore > Configure Communication. Select the communications port and baud rate that you are using. Select either checksum and accept the default time for the time-out. Step 2. Select Explore > Connect > Local.
4.3 Using Terminal Emulation Software This section provides detailed instructions on how to use terminal emulation software to access the Serial Converter so that you can view and edit Serial Converter parameters or view the Serial Converter event queue. A variety of terminal emulation programs can be used to establish a serial connection between a computer and the Serial Converter.

APPENDIX C Flash Updates Appendix C provides information on updating peripheral product firmware. C.1 Preparing for a Flash Update A Flash update should be preformed when updated peripheral product firmware is available. Please take the following precautions to ensure a successful Flash update: • Obtain the new firmware version from Rockwell Automation. Save it to the hard drive of the computer. Do not attempt to perform a Flash procedure from a floppy disk or a network.
C.2 Performing a Flash Update with HyperTerminal ! ATTENTION: When you perform a Flash update, the product will fault if it is receiving control I/O from the Serial Converter. Verify that the product has stopped safely before beginning a Flash update. Failure to observe this precaution could result in bodily injury and/or damage to equipment. ATTENTION: If you interrupt a Flash procedure that is updating boot code, the device may become inoperable.

GLOSSARY application code - Code that runs in the module after the boot code calls it. It performs the normal operations of the system. block check character (BCC) - An error detection scheme where the 2s complement of the 8-bit sum (modulo-256 arithmetic sum) of all data bytes in a transmission block. It provides a means of checking the accuracy of each message transmission. boot code - Code that runs when the module first receives power. It checks basic operations and then calls the application code.
