Complete the following procedure to load the Main Firmware. Use this procedure only if
the normal defaults specified for the
*.bat
file are acceptable. If you want to customize
this installation, refer to Table 5-16.
1. Set up the instrument for RS-232 communications as described in “Calibration
Procedure (Manual)“ in Chapter 4, only use a baud rate of 38400 instead of 19200.
Note which PC COM port was used for the RS-232 connection.
2. At the PC, obtain the DOS prompt
C:\>
. (Do not shell to the DOS prompt from
Windows.)
3. If you have not already done so, copy the contents of the diskette into a directory on
your hard drive, e.g.,
firmware
, and change to this directory (
C:\firmware>
).
4. After the DOS prompt in the directory with the diskette files, type load451.bat if
you connected to PC COM port 1, or l
oad452.bat
if you connected to PC COM
port 2. For example, type the command
C:\firmware>load451.bat
; then press
<Enter>.
5. Observe the checklist for this installation, a pause (press <Cntl><C> to escape at this
point), and then press any key to the launch the executable
ld26xx.exe
with its
appropriate switches for this loading application (see Table 5-16).
6. While loading; the instrument display shows “boot.” Allow several minutes for the
firmware loading process to complete. The PC screen will show Loading Line as the
firmware is loaded. Do not interrupt this process by touching the PC keyboard or
removing power from the instrument. After the completion of the firmware, the screen
shows Done Loading and the DOS prompt is returned.
7. To confirm the successful loading of the new firmware, see “Diagnostic Tool idS”
earlier in this chapter and note the new version of the Main Firmware identified as
Main .
Loading the A/D Firmware 5-41.
The instrument A/D Firmware is stored in an electrically erasable and programmable Flash
memory (A3U6). The Program Power for A3U6 is from an external source at A3P2 (or
A3J3) and the firmware loads from an internal connection at A3P1. This means you must
remove the case to load the A/D firmware. The A/D Firmware is specific to the 2640A or
2645A. Be sure you are loading the correct program.
Complete the following procedure to load the A/D Firmware. Use this procedure only if the
normal defaults specified for the
*.bat
file are acceptable. If you want to customize this
installation, refer to Table 5-16.
1. Remove the instrument case as described in the procedure “Removing the
Instrument Case” in Chapter 3.
2. Locate contacts for A3W5 and install a jumper across these contacts. This connects
Vcc to the line VBOOT (for the A3U5 microprocessor) and prevents A3U5 from
initializing the A3 A/D Converter PCA kernel.
