VERIFYING SYSTEM OPERATION
USING THE NETWORK DIAGNOSTIC ANALYZER
The Network Diagnostic Analyzer is used to analyze the status of the network. This analyzer
is invaluable to the successful installation and repair of the network. With it you can:
• Confirm overall network integrity.
• Confirm individual node operation.
• Locate a faulty node.
CONNECTION TO THE NETWORK
The Diagnostic Analyzer connects to any spare port on any hub. To test the Control 2, the
Diagnostic Analyzer may be connected directly to the Control 2.
CONFIRM NETWORK INTEGRITY
The Diagnostic Analyzer can be used to confirm that data can be communicated over the
Sonance Navigator Network. If data can communicate over the network, the network wiring
is generally correct.
To confirm network integrity, do the following:
1. Connect the Network Analyzer to any Network Hub.
2. Verify the RECV (Receive) and XMIT (Transmit) lights flicker.
3. Verify ST1 and ST2 illuminate.
If ST1 and ST2 fail to illuminate, the Diagnostic Analyzer will continue trying to establish com-
munication with the Control 2 once per second until it successfully communicates. Try the fol-
lowing:
• Remove hubs from the network one at a time until the ST1 and ST2 illuminate. It is OK to
remove hubs with power connected.
• Remove nodes from hubs one at a time until ST1 and ST2 illuminate. It is OK to remove
nodes with power connected.
Once ST1 and ST2 illuminate, they will stay illuminated for up to two minutes even if the net-
work is no longer functioning. If errant devices/wires are connected and need to be confirmed
after the Diagnostic Analyzer has successfully communicated with the Control 2, then it will
be necessary to remove and restore power to the hub powering the Diagnostic Analyzer.
You can verify a node is functional right from the hub. Simply disconnect then reconnect
power to a node. You should see the RECV and XMIT lights flicker as the device registers on
the network.
