Daisy Chain Autoconfigure
Note: All secondary readers must be set to Serial for Daisy Chain to function.
When setting up a daisy chain operation, perform the following steps:
1. Set the primary imager (the one connected to the host) to Serial.
This sets all the imagers in the chain to Serial when the command is executed.
Before Autoconfigure you must set the primary imager to Serial (S):
2. Send < K150DAISY >.
3. If necessary, set the primary imager to Edge.
After Autoconfigure you may set the primary imager to Edge (S), but the other imagers
must remain in Serial (S):
Usage:
For quick setup and configuration of your daisy chain network.
Definition:
The command to autoconfigure the daisy chain is sent to the primary
imager and the software responds in the following ways:
• 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 (the primary reader’s ID being a 0).
• Propagates the communications settings and the relevant operating
modes of the primary imager to the host and auxiliary ports of each
secondary reader.
• Resets each secondary reader.
• Confirms that each secondary reader has acquired the new settings.
