PCC-10 User's Guide 3-9
Once the node is in the configured state, the control panel will enter a receive-
ready state and will display the following message while waiting for a service pin
message from another node on the network:
Now waiting for a service pin message.
Once the service pin is pressed on the other node and a service pin message is
received, the control panel will then perform a request/response diagnostic message
to the other node using Neuron ID addressing. It will repeat this operation,
referred to as a “ping,” once a second until either the ‘OK’ or the ‘Quit’ button is
chosen (the Comm button becomes the Quit button).
Received service pin, pinging node:
Neuron ID: 01 23 45 67 89 10

This series of tests is intended to confirm that the PCC-10 card can be configured
and can communicate with a node on the network. The Comm function is intended
to eliminate the PCC-10 card, the card drivers, the network connection, the
hardware of the other node, and the topology configuration from the list of possible
problem points or points of failure during network troubleshooting. The Comm
function does not eliminate the possibility that the wrong type of medium has been
used. Be sure that the medium is suitable for use in the intended channel
topology. The Comm function also does not eliminate the possibility of poor
network termination. The network wiring may work for this test but may fail if
multiple nodes are communicating. Be sure to verify proper termination when
troubleshooting communication problems. This feature was not designed to work
across routers.
Service
The Service button will cause the PCC-10 card to broadcast a service pin message
on the network. The service pin message will not be sent if the PCC-10 card is in
the post-reset flush state (see Automatic Flush Cancel).
Restart
The Restart button clears the image of the PCC-10 card’s Neuron Chip and places
the card into the ‘boot’ state. This is the device state found following an insertion
of the card or a re-boot of the operating system. When this function is chosen, a
dialog box will appear asking for confirmation of this command.
Reset
The Reset button causes a reset of the Neuron Chip in the PCC-10 card, but does
not clear the Neuron Chip’s system image.
