9.5 Other Troubleshooting Tips
9.5.1 Nothing shows up in a List Command
A List command on the serial port should provide a list of addresses, IDs,
I/Os and parameters of slaves on the network. If the command doesn’t display
this list:
• Check AS-i power is connected
• Verify you have an AS-i power supply. The supply must be a
genuine AS-i power supply and not just a generic supply
• Verify the power supply polarity is correct
• Check the AS-i cable to the master
• Try the List command with only one slave on the network. If there
are duplicate slaves or a slave at address zero, you might not see any
of the slaves
9.5.2 Finding Failed Slaves
To find failed slaves, do a List command on the serial port. A failed slave will
have PID and PIO values displayed but no corresponding ID and I/O values.
9.5.3 Unable to go Online
Try running with a minimal G file. Set only the following items:
• Word 1 = 8000h
• Word 63 = 3543h = 13635 decimal
9.5.4 Unplugged Phoenix Connector
If you unplug the Phoenix connector, the connection through the scanner is
lost and the slaves won’t have AS-i power.
9.5.5 Scanner and Hand-held Programmers
You cannot have both the scanner and a hand-held programmer on the
network at the same time. They both act as masters.
