5-38 QX Hawk Industrial Imager User Manual
Communication
Daisy Chain Autoconfigure
For quick setup of a daisy chain configuration.
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 imagers in the daisy chain.
Assigns an internal ID number (1...n) to each secondary imager, where the first secondary
imager is number 1 (the primary imager’s ID being a 0).
Propagates the communication settings and the relevant operating modes of the primary
imager to the ports of each secondary imager.
Resets each secondary imager.
Confirms that each secondary imager has acquired the new settings.
When setting up a daisy chain operation, perform the following steps:
1. Set the primary imager (the one connected to the host) to Serial Data Trigger Mode.
This will also set all the imagers in the chain to
Serial Data
when the command is executed.
Important: All secondary imagers must be set to Serial Data Trigger Mode for Daisy
Chain to function.
Before Autoconfigure, the primary imager must be set to Serial (S):
2. Send the <K150DAISY> command from ESP’s Terminal.
3. If necessary, set the primary imager to External Edge.
After
Autoconfigure
, the primary imager can be set to
External Edge
(
E
), but the other
imagers must remain in
Serial
(
S
):
Pre-Setup Requirements:
1. Start setup by matching the communication settings of the “downstream” port of the
primary imager to the “upstream” ports of the secondary imagers. It may be necessary
to set up all the “upstream” ports first so the chain can pass information.
2. “Downstream” ports on secondary imagers will be set up automatically during the
setup process.
3. If the imager is Ethernet-enabled, first check to determine if RS-232 B is available. If it
is available, set RS-232 B as the Source port in Array Communication Modes.
Otherwise, set RS-232 A as the Source port. Port Routing for Symbol Data Output
and Extended Data will be disabled on the Source port.
