Device description
Implementation
STM8SPLNB1 device is receiving DiSEqC signal on the coaxial cable, decoding and
processing the DiSEqC commands. As a result, legacy matrix or I
The STM8SPLNB1 device can also send DiSEqC answer back to master through coaxial
cable.
STM8SPLNB1 is designed for usage with LNB devices with I
pins control (see
used in LNB application (see http://www.st.com for more SaTCR1 information).
Behavior of STM8SPLNB1 devices can be modified through a set of configuration
parameters which are stored in device data EEPROM memory. Configuration is done also
through specific DiSEqC commands. After final configuring the device can be locked to
given configuration (vendor configuration).
