Flash loading of AXIS CD servers via the parallel port1

Equipment needed

* Compatible PC 286 - 486
	640 Kbyte memory, DOS ver. 3.3 or newer
* CD server flash loading kit
	Flash loading cable (14467) 
	Diskette with loading software FSTPRN.EXE 
	Instruction
* CD server to be updated
* File with firmware to be loaded
* Screwdriver

Step by step description

1. Disconnect the power supply and other external connectors.

2. Loosen the two screws holding the back plate of the enclosure

3. Pull out the back plate until the PIN-head array for the
   parallel cable is accessible

4. Connect the parallel cable to the PC LPT1 port and to the 26-pin
   array on the CD server circuit board. Make sure the parallel cable
   connector is mounted with the arrow, close to pin 1,  facing the
   ETRAX chip located in the middle of the PCB.

5. Reconnect the power to the CD server

6. Copy the flash load software (FSTPRN.EXE) and the updated firmware
   file to a common directory.

7. Start the loading sequence with the DOS command:

fstprn "firmware file"
 
It is also possible to load the CD server with the standard DOS copy
command:

copy /b "firmware file" LPTx 		(x = LPT port no.)

Note! Do not forget the /b (for binary) switch in the copy command.
There should be no printer definitions for the LPT port used.

How to monitor the loading procedure
* When the loading is started, the network LED will start flashing with
  a rate of 2 Hz (loading time between 30 sec and 4 min).

* The loader will consider itself completed and the led will flash with
  a rate of 0.5 Hz.
 
* In case of error, the flashing rate will be 1 Hz (with the on period
  much longer than the off period). It has been reported that some
  PC-models do not work with the fstprn software, if this happens please
  try using another PC.

8. If you have made a firmware update including parameter changes
   (e.g. from 1.x to 2.x) a reset to factory defaults is required. To
   do this:

* Power off
* Short circuit pin 1 and 2 in the 26 pin-array.
* Power on and off.
* Remove the short circuit.

	
Note:

The parallel port load is only needed when upgrading CD servers with
a firmware version older than 2.00. Units with Firmware revision 2.00
and later can be flash loaded via the network. For instructions please
refer to the CD server documentation or the readme.txt file in the CD
server root directory.
