MULTIPLE ADAPTER RESPONSE DETECTION CIRCUIT |
摘要 |
An adapter response circuit indicates the number of adapters on a link responding to a given address and hence permits the detection of possible data collisions. Each adapter responding to the address transmitted on the link induces a current on a common conductor. The magnitude of the current unambiguously identifies the number of adapters responding to that address. The proper resistive termination of the link may be checked by inducing a similar incremental current on the conductor and evaluating a voltage variation indicating the presence or absence of a termination resistor.
