General Transmitter Information
Damping information
The SITRANS LC500 transmitter implements damping on most of the transmitter
variables. The damping setting may vary from 1 (shortest value) to 10000 (longest value).
Non-volatile Memory Data Storage
The flags byte of Command #0 referenced in the Universal Command Specification
document will have Bit #1 (Command #39, EEPROM Control Required) set to 0, indicating
that all data sent to the transmitter will be saved automatically in the non-volatile memory
upon receipt of the Write or Set Command. Command #39, EEPROM Control, is not
implemented.
