Programmers: HW-130: Installation and Debugging tips (PC platforms)
Record #926
Product Family: Hardware - Make sure there is enough conventional memory to launch the program. You need to have 470K of base memory available. Type 'mem' from the DOS prompt, look for the line 'Largest executable program size ...Kbyte'. If there is not enough memory, unload some device drivers in the config.sys or autoexec.bat files (restart the PC). - The software assumes the default addresses and IRQ settings on the com ports: com1 com2 com3 com4 Addr: 03F8 02F8 03E8 02E8 IRQ: 4 3 4 3 - Run 'msd'; Run 'msd' (Microsoft diagnostics) from the DOS prompt, type in 'C' for Com ports, and check that there are TWO COM ports available (two 16550 UART Chips). (The additional port is required to support your mouse.) The other settings of the COM ports like the baud rate, data bits etc. do NOT matter. The HW130 software takes care of this. Make sure the address used is correct for the COM ports. Type in 'Q' from the main menu of MSD for the IRQ settings on the PC. Make sure IRQ3 points to com2 and 4, and IRQ4 to com1 and 3. - If all else fails, reboot the PC and enter the CMOS setup by hitting the 'DELETE' button during the rebooting of the PC. Search around for the COM ports and try swapping the COM ports (i.e. use a different UART for the programmer). Point com1 to com2 and com2 to com1. If there is only one com port, point it to com1 instead of 2 (or vice versa). Exit and save the CMOS setup and try again. Once you have established communications with the programmer, lower the BAUD rate in the communications dialog down to say, 9600 BAUD (leave the com port set to 'AUTO'). Once communication with the programmer has been reestablished, from the Options menu, select 'Save Settings'. This will create a hw130.ini file and save the BAUD rate. The next time the programmer software is used, communications will only be done at 9600 Baud, or whatever rate you saved to the .ini file. Solution 2: Check that you are using a standard serial cable and/or 9-25 or 25-9 pin cable adapters. Null modem cables will not work. End of Record #926 - Last Modified: 07/29/99 18:10 |
