Updating Firmware in the DSM314
The DSM314 operating firmware is stored in on-board FLASH memory. The firmware
update is provided on a floppy disk. The PC Loader utility controls downloading the new
firmware from the floppy to the DSM314 FLASH memory and is a DOS-based program.
For Windows, Winloader is also available. 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. The Winloader
update utility requires Windows 95, Windows NT, or Windows 98. The hardware
required to run these operating systems should suffice to also run Winloader. Winloader
requires about 500Kbytes of hard disk space.
Warning
The user MUST determine that the PC is connected to a DSM (and not a
PLC CPU or other module that supports FLASH firmware upgrades) before
entering Boot mode. Failure to do so can cause loss of PLC 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 PLC 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 DSM302 module to be updated (slave).
DOS Update
Note: This section only applies to those running the DOS Loader update program from DOS.
For those using Windows software, refer to the next section “Windows Update.”
5. (DOS) Insert a labeled floppy disk in drive A: or B:. Ensure that the floppy is not write
protected. Run the self-extracting archive specifying drive A: or B: as the destination
when prompted with “Unzip to folder:”.
6. (DOS) At the C:\> prompt, type A:install (or B:install if your floppy drive is B:). The install
program will copy several files to the hard drive then invoke the PC Loader. Install
can also be run from the floppy drive directly if there is no hard drive or not enough
