Omega Speaker Systems LCIC-WIM-BEN manual RS485 Address selection, setting & reading

h. RS485: Address selection, setting & reading

(for more details and examples refer to section D.5; except ‘Nx<c/r>’, these commands are available also in the fill mode):

	Activate the board addressed x. x is between 1 and 64.
	Notes
:x<c/r>	1. Wait 10 ms after sending the colon (‘:’) before
	sending the rest of the command (‘x<c/r>’).
	2. Wait 30 ms after sending the ‘:x<c/r>’ command
	before analyzing the response(s).
	“Hello” command: prompt all existing boards to respond.
	Notes
:999<c/r>	1. Wait 10 ms after sending the colon (‘:’) before
	sending the rest of the command (‘999<c/r>’).
	2. Wait 1000 ms after sending the ‘:999<c/r>’
	command before analyzing the response(s).
	Read the RS485 address of the active board.
	Board’s response:
	’#x<c/r>’, where x is the address of the active board.
	x=0 means that the board has been configured as a non-
	RS485 device. Other value (between 1 & 64) specifies the
	RS485 address of the active board.

nNotes

1.Wait 1 second after sending the ‘n’ command.

2.If no board is active, there will be no response.

3.In case of malfunction, more than one ’#x<c/r>’ will be responded in sequence. This is theoretically impossible but should be checked in order to be on the safe side.

	Set the required RS485 address. x is between 0 and 64.
	Board’s response: ‘OK<c/r>’.
	(x=0 sets the board as a non-RS485 device; this will
	facilitate your coding, as no ‘:x<c/r>’ command will be
Nx<c/r>	needed.)
	Notes
	1. The address setting takes effect only upon board
	reset.
	2. When the RS485 address is not 0, its value is shown
	for a while on the LED display upon board reset.
