CHAPTER 3 Installing the Serial Converter Chapter 3 provides instructions for installing and removing the serial converter. 3.1 Selecting Cables The following cables are all you should need to connect the serial converter to a product and computer. 1 # 1 2 2 Description DPI cable to connect the serial converter to a drive. Serial cable to connect the serial converter to the computer. Part Number RECBL-M10 RECBL-SFC Figure 3.
3.2 Installing the Serial Converter Use the following procedure and refer to figure 3.2 to install the serial converter. Step 1. Connect the serial converter to the product using the RECBL-M10 cable. Step 2. Connect the converter to the computer using the RECBL-SFC cable. RX Step 1 TX Step 3. Verify that power is applied to the product. The serial converter receives power from the product. Therefore, the product must be powered before the serial converter will operate. Step 2 Figure 3.
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. For definitions of terms in this chapter, refer to the Glossary. 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.
4.3 Using VS Utilities to Configure the Serial Converter With VS Utilities software, you can edit parameters in both the serial converter and the connected product. On a DPI product (for example, a SP600 drive), you can also edit parameters in any of the attached peripherals. 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). Step 1. Select Explore > Configure Communication.
4.4 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.

If no text or meaningless text appears instead of the Main Menu, adjust the baud rate in your software. Refer to section 5.5 for detailed instructions. To Navigate in the Terminal Emulation Software Table 4.2 describes the keys to used to navigate the terminal emulation software. Table 4.2 – Key Descriptions Key Description 0 ... 9 In the main menu, keys 1 – 3 select a menu option. In the parameter screen, keys 0– 9 enter a value. Display the main menu or abort changes to a parameter.
4.4.2 Setting the Fault Action ! ATTENTION: The setting of Comm Flt Action (04) determines the action of the serial converter and connected product if DF1 serial communications are disrupted. By default, this parameter faults the product. You can set this parameter so that the product continues to run. Ensure that the setting of this parameter does not create a hazard. Failure to observe this precaution could result bodily injury and/or damage to equipment.
4.4.3 Resetting the Serial Converter ! ATTENTION: If the serial converter is transmitting control I/O to the product (indicated by a solid green diamond LED), the product may fault when you remove or reset the serial converter. Determine how your product will respond before removing or resetting a connected serial converter. Failure to observe this precaution could result bodily injury and/or damage to equipment.

APPENDIX C Flash Updates Appendix C provides information on updating DPI host or peripheral product firmware. C.1 Preparing for a Flash Update Please take the following precautions to ensure a successful flash update: • Obtain the new firmware version from Reliance Electric. Save it to the hard drive of the computer. Do not attempt to perform a flash from a floppy disk or a network. • Read all instructions supplied with the new firmware file.
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 or is receiving control I/O from an alternate source before beginning a flash update. Failure to observe this precaution could result bodily injury and/or damage to equipment. ATTENTION:If you interrupt a flash procedure that is updating boot code, the device may become inoperable.
Step 2. If the flash can be completed safely, type Y. The letter “C” repeatedly appears. It is the Xmodem prompt and continues to appear until you send a binary file. Important: Press Ctrl + X to cancel a flash update procedure. Step 3. Select Transfer > Send File to display the send file dialog box. See figure C.2. Step 4. Click Browse and navigate to the flash file. Step 5. Double-click the file. Its name appears in the Filename box. Step 6. In the Protocol box, select Xmodem. RECOMM232.bin Figure C.
C.3 Troubleshooting Potential Flash Problems Table C.1 – Flash Troubleshooting Problem Description “Transfer Cancelled by Remote System” message appears and the flash is not completed. Corrective Action • Restart HyperTerminal and repeat the flash procedure. • If you are using Windows NT 4.0, install SP3 or later. Windows NT service packs are available from the Microsoft web site: http://www.microsoft.com. • Download a HyperTerminal Private Edition update from the Hilgraeve web site: http://www.
GLOSSARY application code - Code that runs in the adapter 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 adapter first receives power. It checks basic operations and then calls the application code.
flash update - The process of updating firmware in a device. hold last - When communications are disrupted (for example, a serial cable is disconnected), the converter and product can respond by holding last state. Hold last state results in the product receiving the last data received via the DF1 connection before the disruption. If the product was in RUN mode and using the reference from the converter, it will continue to run at the same reference.
