S-link Port Message

This section is about port message on the S-link ports, which are S-link Control-A1 messages.

Collisions

Collisions occur on the S-Link bus in the same way they do in any bus-architecture network: where more than one device tries to talk at the same time. A collision could occur between 2 S-Link devices (i.e. CD players) or between the Slink-e and a S-Link device. Like most networks, S-Link devices avoid collisions by waiting until the line is clear before talking. Slink-e obeys the same protocol and doesn't attempt to talk until other devices are done. If two devices attempt to talk simultaneously, a collision can still occur.

Slink-e automatically detects collision errors and reports them to you. Additionally, since the Slink-e loops back outgoing port messages, you can verify that your message was sent legibly. Since the Slink-e has four S-Link ports, you can reduce the likelihood of collisions by placing devices on separate ports.
