3.2 Reset (simply link jumper 1 and remove)

With ACU power on, link the reset jumper J1 together (short with jumper provided) for a
few seconds. Then remove and park (place jumper on 1 pin only). Reset complete, this
will lose all cards from memory and put back factory defaults except for any Readers
configured into special formats will not be changed.

3.3 Firmware

EX series ACU's have Flash Upgradeable EEPROMS called FPROMs (Field Programmable
Read Only Memory)
EX series version 3 firmware is required for the Version 3 hardware EX series controllers.
Version 3 firmware is not compatible with Version 2 Hardware and vice versa.
For version 3 hardware boards such as the latest EX series controllers you need version 3
firmware. I.e. file names such as EX2_305.S2.
The new Version 3 Expanders (Unlike version 2) are now Flash Upgradeable.
All Hardware Version 2 and Version 3, Experts and Expanders are interchangeable and
compatible.
3.4 How to upgrade EX series ACU with new
Firmware
To upload Firmware you need the new Xinstaller.exe version (v3.xx) which can be used
for uploading firmware's version 2 and version 3.
Basic Principle of operation
Using a simple software application called Xinstall.exe you will execute this which will
view the associated Xinstall.ini file, telling it how to connect to the ACU, and
automatically send down the Firmware Data to the ACU.
Therefore you need 3 files.
1. Xinstall.exe
2. Xinstall.ini
3. The Firmware File "xxxx.abs"
Place all three files in the same location or folder.
It may be the ACU is not ready to receive New Firmware. To place the unit into ready
mode you can perform a procedure that resets and manually erases the firmware
loaded into the EX-series.
1. Power down the EX-series
2. Place Jumper on Reset J1
3. Power Up (this will be confirmed by beeping)
4. Press and continue to hold the tamper switch on.
5. Remove jumper & replace again within 15 seconds.
6. Release tamper switch
7. Power down
