RS-232 Auxiliary Port
Daisy Chain Autoconfigure
Note: Not in ESP.
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 it's 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
secondary reader.
• Resets each secondary reader.
• Verifies that each secondary reader has acquired the new settings.
Serial Cmd: <K150DAISY>
Note: All secondary readers must be set to Serial for Daisy Chain to function.
See "Trigger" on page 7-6.
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.
Before Autoconfigure you must set the master reader to Serial (S):
Master
Host
Reader
S
<K150DAISY>
2. Send
3. If necessary, set the master reader to Edge.
After Autoconfigure you may set the master reader to Edge (E)
but the other readers must remain in Serial (S):
Master
Host
Reader
E
