General Transmitter Information

Damping information

The SITRANS LC 500 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.
