Updating Firmware in the DSM314 458
Appendix F: Updating Firmware in the
DSM314
The DSM314 operating firmware is stored in on-board FLASH memory. The Winloader
update utility requires Windows 95, Windows NT, or Windows 98, or Windows 2000. The
hardware required to run these operating systems should suffice to also run Winloader.
Winloader requires about 500Kbytes of hard disk space.
The DOS-based PC Loader utility controls downloading the new firmware from the floppy to
the DSM314 FLASH memory. PC Loader requires an IBM AT/PC compatible computer with
at least 640K RAM, one floppy drive, MS-DOS 3.3 (or higher), and one RS-232 serial port. In
order to run this utility within an MS-DOS box under Windows® 3.1, Windows 95 or
Windows NT, the processor should be at least a Pentium 133. If not, the computer should
be rebooted into MS-DOS mode. PC Loader functions optimally with a hard drive with at
least 1 MB available space.
WARNING
The user MUST determine that the PC is connected to a DSM (and not a Host Controller CPU
or other module that supports FLASH firmware upgrades) before entering Boot mode.
Failure to do so can cause loss of Host Controller CPU Program and Configuration.
To Install the New Firmware, Perform the Following Steps:
1.
Save or back up any programs or data resident in the module before performing the
update function.
2.
Place the Host Controller in STOP/NOIO Mode. (Clear any faults.)
3.
Ensure that the module’s SNP serial port baud rate is set to 19200 baud.
4.
Using a Station Manager to PC cable, IC693CBL316, connect the appropriate serial
port of your computer (master) to the DSM314 module to be updated (slave).
