The E520.30 PC driven demonstrator kit is for demonstration purpose of the smoke-detector device functionality. It supports
communication between PC and smoke detector based on E520.30 using the E520.30 Interface (3 level interface). The E520.30
device inside the smoke detector has a special firmware to communicate with the PC using the same protocol.
The PC demo software provide smoke detector device control and parameter modification with graphical output.
For demonstration purpose it is necessary to establish a communication between smoke detector and PC using physical se-
quential interface on two wire bus (LN24 and GND).

5 PC based Demo Software:
Start the program smoke.exe.
The program connects automatically to the smoke detector via E520.30 interface.
After connecting the software shows the measured supply voltage and the LN24 supply. The LN24 supply can be set in LN24
Properties window.
To see the smoke density values choose in Functions Remote smoke detector and a history windows appears. Move IR and AMP
sliders to values around 5 :

The LN24 voltage is measured with the E520.30 interface and can also be displayed.
LN24 properties can be inspected with LN24 Properties option in the Menu Bar Functions. The following values must be set
for correct communication with the firmware (default at delivery), press “save to EEPROM” button to store new values inside
the µC in the E520.30 interface :

The E520.30 register values can be read by pressing the readAllRegs button. To change a value click in the nVal field and fill in a
new value in the upcoming window. Confirm with OK. Optionally change more register values and press writeAllRegs to trans-
fer new data to the E520.30.

The E520.30 interface can be used to flash new content into into the E520.30 device.
To flash new software, please do the following :
• remove connect state in the Function pull down menu in main window
• disconnect smoke detector from E520.30 interface
• open the E520.30 interface, plug in the 14pin ribbon cable into CON4 and connect to 8 pin connector at the bottom of the
smoke detector housing – the 8pin to 14pin adapter only fit in one position
• connect again in the Function pull down menu in main window
• choose Flash in the Memories pull down menu in main window, a new Flash window appear, see Figure 8
• press Load button and choose HEX File for E520.30 device, after reading the hex file the Flash window is filled with data,
see Figure 9
• to program new data first erase Flash by pressing Erase button, then press Write button – a progress bar is visible, see Fig-
ure 10.
• press Verify button and a verify ok window appear, see Figure 11.
• optionally change LN24 properties for new firmware, see Figure 5.
• disconnect smoke detector, remove 14pin ribbon cable and connect green 3pin connector to E520.30 interface and con-
nect again.
