Introduction
Before you can put a D20ME II module into service, it must have a firmware
application code loaded into memory.
All D20ME II boards use Flash memory to store the application code.
Serial
Download
You can load the Flash code file serially into the memory of the D20ME II via the
68K Monitor using most types of Windows communication software, such as
HyperTerminal.
Table: Identify
the D20ME II
Type
The D20ME II module type is determined by the version of BootROM installed,
which identifies how the module will be used. Because the download method
depends on which BootROM is installed, you need to determine the type of D20ME
II module before downloading the Flash code.
Note:
The /xx in the Label column is the software revision number.
Module Type BootROM Label
D20ME II D20 Base SBU0000/xx
D20ME II ME CCU SBU0001/xx
Prerequisites
for Code
Download
You need the following items to successfully load a Flash code file into a D20ME II
module:
• Windows PC with HyperTerminal (or equivalent) communication software
loaded.
• The code file, in the Motorola S-record format, located on a local hard drive. If
the file is located on a network or floppy drive, the download may be
significantly slower.
− This file is typically named: down.shx.
• A WESMAINT cable for connecting the PC to the D20ME II WESMAINT
serial port
• The D20ME II card:
− with the hardware option jumpers set
− installed in a D20 or D200 chassis and ready to power-up.
