REPLACING THE 16BIT I/O PCB
NOTE:
Replacing the 16bit I/O PCB may take up to half an hour to complete. Please ensure that any
important keys are removed from the systems prior to the replacement, as it may be difficult to obtain the
keys.
NOTE:
The small secondary backup battery (located on the
) can retain the data held in
memory for only 30 minutes. After this time the data will be lost for good. Therefore it is more important
than ever to complete a 'Read All System Data' prior to servicing a 16bit Traka system.

Select the appropriate system from the
drop down menu that you wish

before working on the Traka system.
5.
Using the Master Key, unlock the Pod Lock. The Control Panel is hooked in at the bottom and locked at
the top. Carefully begin to remove the Control Panel.
6.
You will see that there are several wires connected to the
attached to the control panel.

Carefully disconnect any wires from both PCB’s noting where and how they connect and completely remove
the control panel.
9.
Place the Control Panel on a suitable flat surface.
10.
Remove the four M3 x 12 hex fixing screws that hold the 16bit Control PCB in place.
11.
Check that the
are set correctly on the new 16bit I/O PCB by copying the settings
from the old 16bit I/O PCB. The Traka 32 communications switch setting is on the bottom side of the PCB.
12.
If an RS232 reader or other serial peripheral device is using UART B, then ensure the UARTB switch setting
is also set correctly. This is located on the bottom side of the PCB.
13.
Place the new 16bit I/O PCB back on the Control Panel and secure with the four fixing screws.
14.
Re-connect the short 34 way ribbon cable from the 16bit I/O PCB to the 16bit Control PCB.
15.
Hook the Control Panel into the bottom of the Pod. Whilst holding the control panel, carefully re-connect
the wires to the 16bit Control PCB and 16bit I/O PCB. Refer to the
for their respective connection diagrams.
16.
Set the On/Off switch on the 16bit I/O PCB to On.

starts to flash. If there is no
Power LED, set the On/Off switch to Off and re-check all of the connections before trying again.
18.
Ensure the LCD is scrolling with the date and time displayed.
19.
Close the Control Panel carefully into the Pod and lock with the Master Key.
The Control Panel should fit easily, if not check that no wires have become caught or trapped between the
Control Panel and the Pod.
20.
Double check the LCD is still On and scrolling with the date and time displayed.
21.
If the database has not been retained in the 16bit Control PCB memory due to it being disconnected for more
than 30 minutes, it will need to be synchronised with the Traka 32 database. From the
