Daisy Chain Autoconfigure
Note: All secondary readers must be set to Serial for Daisy Chain to function.
When setting up a daisy chain operation, do the following:
1. Set the master (the reader connected to the host) reader to Serial.
This sets all the readers in the daisy chain to Serial when the command is carried
out.
2. Send <K150DAISY> command.
3. If necessary, set the master reader to Edge.
Usage: For quick setup and configuration of the daisy chain network.
Definition:
Daisy Chain Autoconfigure is issued to the master reader in the daisy
chain and the software responds as follows:
• Counts the number of secondary readers in the daisy chain.
• Assigns an internal ID number (1...n) to each secondary reader, where
the first secondary reader is number 1 (and its own ID being a 0).
• Propagates the communications settings and the relevant operating
modes of the master reader to the host and auxiliary ports of each sec-
ondary reader.
• Resets each secondary reader.
• Verifies that each secondary reader has acquired the new settings.
Serial Cmd: < K150DAISY >
