Nexia Manual LTR
To turn echo OFF during a session:
Send byte sequence 0xFF 0xFE 0x01.
Receive 3 byte response from server (0xFF 0xFC 0x01 = echo OFF).
Send desired commands.
To turn echo back ON during a session:
Send byte sequence 0xFF 0xFD 0x01.
Receive 3 byte response from server (0xFF 0xFB 0x01 = echo ON).
Send desired commands.
Command
SET – Tells Nexia that a DSP attribute is to be set to a specific value – may contain negative
numbers and/or decimal points
GET - Tells Nexia that a DSP attribute is to be read – the response may contain a decimal point
and/or a negative number (see
Responses ).
INC - Tells Nexia that a DSP attribute is to be incremented by a specific amount
DEC- Tells Nexia that a DSP attribute is to be decremented by a specific amount
RECALL – Tells Nexia that a preset is to be recalled.
DIAL – Tells the Nexia that a dial command is being sent
SETL and GETL can be used if negative numbers and/or decimals are not supported by a control
system.
SETL – Tells Nexia that a DSP attribute is to be set to a specific value, no decimal places or
negative numbers –To convert a dB number: add 100 to the desired level and then multiply by 10.
Example: To set a level to –60.5dB, add 100 (-60.5 +100 = 39.5). Then multiply by 10
(39.5 X 10 = 395). Instead of Value being –60.5, Value after this SETL command will
equal 395.
GETL - Tells Nexia that a DSP attribute is to be read without negative numbers or decimals. To
convert this number to dB: divide the number by 10, then subtract 100.
