As any text editor or communications program can be used for these purposes, the use of Windows XP is described only as an illustration. The following example shows how Windows XP accessory programs Notepad and HyperTerminal can be used to create a boot-file on a PC, and send it to the OEM4/OEMV receiver. It is assumed that the PCs serial port COM1 is connected to the receivers COM1 port, and that a remote terminal is connected to the receivers COM2 port. 1. Open Notepad and type in the command strings to be sent to the receiver upon start up. For example: com com2 115200 n 8 1 n off off log com2 bestposa ontime 1 log com2 rangea ontime 1 log com2 rxstatusa onchanged log com2 rxconfiga once 2. Save this with a convenient file name (for example, C:\GPS\BOOT.TXT) and exit Notepad. 3. Ensure that the HyperTerminal settings are correctly set up to match the settings with the receivers communications protocol. These settings can be saved (for example, C:\GPS\OEMSETUP.HT) for use in future sessions. You may wish to use XON / XOFF handshaking to help prevent loss of data. 4. From the Transfer menu, use the Send text file selection to locate this file to be sent to the receiver. Once you double-click on the file or select Open, HyperTerminal will send the file to the receiver. Note: - Please ensure you have used a carriage return (hit the enter key) after typing the last line. - If you wish these to become part of the permanent configuration of the card, rather than just using them on boot-up, enter the SAVECONFIG command as the last line. - We recommend transferring multiple commands at low connection baud rate like 9600bps. (Transfer multiple commands at high baud rate might cause a race condition at times) - Please use the RXCONFIG log to double check all transferred commands got accepted by the receiver after the transfer.
