transceiver_timing.h File Reference

Detailed Description

The timing constants for the 485 Transceiver.

This header contains the timing constants from E1.11-2008 [DMX] and E1.20-2010 [RDM]. In some cases we allow the user to configure values outside the range in the standards; this is for testing purposes.
