Termination Resistors in Differential Networks
Termination Resistors in Differential Networks:
Differential networks often benefit from the installation of termination resistors. Termination is
rarely required for lower baud rates, for example 9600 baud or less. However, differential
networks are transmission lines, and can suffer from the electrical effects of ringing, or
undershoot and overshoot, all of which can cause data errors, especially at higher baud rates, like
115.2 Kbps. Termination resistors should always be installed at the extreme ends of the network,
as close to the differential transceiver circuits as possible, as outlined in the diagram below.
NOTE: The Blue Heat/Net Sync features software
selectable termination.
