RS-485 Interface
RS-485 Interface is used for networking of the system
components - PC and panels. The range of RS-485 bus
is up to 1200 meters. The number of panels is up to 32.
RS-485 port is protected against overvoltage (60V) and
crosspolarity.
Unshielded four-wire cable may be used for RS-485
wiring. To obtain the maximal range of 1200 meters use
0.4 mm 2 cross section wire. 0.2 mm two-cross section
wire will provide the range of 500 meters .
On the first and last panel in the drop-line short jumpers
S3, S4 and S6 to add the resistive load.
Take care of proper grounding of all panels in the network.
Adress setting
Each panel on RS-485 drop line must have the
unique address from 0 to 31.
To set panel's address proceed as follows:
1. Disconnect feeding of the panel
2. Short terminals TM and BEL
3. Supply feeding. Buzzer will beep several times and current address settings will be
displayed with buzzer beeps and right green LED blinks. The digit is displayed as
number of beeps and blinks with a pause between digits. For example, number 23 is
displayed as:
2 beeps and right green LED blinks, pause, 3 blinks and beeps.
Zero is displayed with continuous sound and LEDs blink. For example, number 04 is
displayed as:
1 continuous sound and right green LED blink then 4 blinks and beeps.
After current address settings displaying, all LEDs blink simultaneously.
4. Enter desired address and press [#] button. Two digits have to be entered
necessarily, for example address 1 is to be entered as [0][1][#].
5. Disconnect feeding of the panel
6. Remove shortage from TM and BEL terminals
Panel is ready for operation with new address.
