In extensive ARCNET networks, delay of data signals
due to cable delays and cycle times of hubs plays a role.
Since the deterministic ARCNET protocol contains
timeout tests, the maximum delay between two time-
sharing devices must not exceed the defined values.
… If you have any questions regarding extensive
ARCNET networks, please contact your local
Pfeiffer Vacuum representative.
