235 Software Load Procedure

  The following procedure requires the use of a terminal emulation
  communications program to install the new 235 software.
  This example shows the procedure using Procomm Plus for DOS.
  Many other communication programs can be used if they are configured
  similarly.

  The key to loading the 235 is to wait for the '->' prompt before
  sending the next line of the ASCII hex software file.  The 235 needs
  time to program the received data into FLASH memory before it can accept
  the next line of the software file.

  The ability to wait for a prompt character makes the download go as fast
  as possible, without overrunning the 235's input buffer.  Procomm and other
  programs have the ability to define a Line Pace Character, which would be
  the '>' character (62 decimal, 3E hex).


  1.  Configure Procomm Plus -

	Go to Setup Menu (Alt-S)
	Select Protocol Options
	Select General Options
	Set Abort Xfer if CD Lost = no
	Select Protocol Options
	Select ASCII Protocol
	Set Char Pacing             = 0 msecs
	Set Line Pacing             = 0 tenths of a sec
   Set Pace Character          = 62  (use '>' as pace character)
	Set CR Translation (Upload) = None
	Set LF Translation (Upload) = STRIP
	Escape out

  2. Connect the computer to the 235 RS-232C interface and observe
     the 235 prompt.  The computer must be operating at the 235
     baud rate of 38400.

        235>

  3. Type "$$DOWNLOAD" at the prompt and enter.

        235>$$DOWNLOAD

  4. The 235 should responds as follows:

   HELP                        Display this screen of commands
   ECHO  (ON,OFF)              Turn character echo ON or OFF
   ERASE                       Erase all FLASH blocks
   ERASE (P1,...,P2,M1,...,M4) Erase specified FLASH blocks
   LOAD                        Erase & start download of Motorola S-record file
   STATUS                      Show Status of downloaded code
   RB      addr                Read   bytes starting  at specified hex address
   WB      addr value          Write  8-bit hex value at specified hex address
   WW      addr value          Write 16-bit hex value at specified hex address
   GO                          Start execution of downloaded code

   Dnld>

  5. Type LOAD at the "Dnld>" prompt.
     Watch FLASH erase messages.
     Special "->" prompt should appear as follows:

   Dnld>LOAD
   Erasing ...
   Param Block 1, 2
   Main Block  1, 2, 3, 4
   ->

  6. Start the FLASH upload.  Use ASCII or text for the protocol.

   Page Up                 (shortcut for Upload)
   ASCII protocol          (select ASCII protocol for upload)
   235_106.hex             (name of file to Upload)


  7. You will observe the ASCII hexidecimal records as they are uploaded.
     This will continue for approximately 5 minutes.

   ->S00B0000313536372E6F75749B
   .
   .
   -S804000200F9

  8. After the last S-record is uploaded, the "Dnld>" prompt should return.

   Dnld>

  9. Type "GO" to run newly loaded application code.

   Dnld>GO
