ST7LNB1Y0 configuration
To configure the ST7LNB1Y0 for the required target application, a dedicated DiSEqC
command is implemented. This configuration is stored in the ST7LNB1Y0 embedded
EEPROM location.
4.1
Command 0Fh
ST7LNB1Y0 devices are shipped to customers with a default parameter value. These
parameters can be updated using a dedicated 0Fh DiSEqC command.
This command has the following format where “data” is the parameter value to be
programmed at the “index” location as shown in Table 16.
Note:
The special command E0 xx 0F FF FF protects the EEPROM data from any subsequent
write access (where xx is the corresponding DiSEqC slave address).
4.2
Command 0Dh
For reading a parameter inside the EEPROM a dedicated 0Dh command has been added.
The command format is described in Table 14, where “index” is the address of the byte to be
read from EEPROM.
The format of the reply frame is given in Table 15, format where “data” is the byte read from
EEPROM.
Timings
The time required to update a byte parameter (write and read operation) is 130 ms, while
the time required to update all parameters is about 3.5 s.

1.
E2h framing (and E4h response) is supported from version 1.1 of the LNB1 software (previously, the
command 0Dh was implemented with E0h framing and the data response was without E4h framing).

After the Command 0Dh, there is a delay of 10ms before getting the reply frame.
