means that an error in a slave node should cause the controller relay output to
indicate an error.
Example 1:
GET NSC
Reply:
00
meaning that neither the LED or Relay will affect status in the slave nodes.
Example 2:
SET NSC 01
reconfigures the settings so that an error in a slave node will cause the controller
relay to indicate an error.
Note! If node is not configured as a node master, an error message will be
produced:
“Error: Node not a System Node Master, parameter not supported.”
12.5.5 ACCESS NODE
12.5.5.1 Overview
This is used to get a direct access to a system slave such as a fiber optic repeater.
12.5.5.2 Description
Communications between the master and a slave is normally performed using GET,
SET and ACT attribues that are sent between the nodes.
For more advanced troubleshooting and in order to perform firmware upload, it is
required to get a transparent channel between the node master and the system
slave, for example between the OMU and the fiberoptic fed repeater in a fiber optic
repeater system.
Format:
ACCESS NODE <Node Number>
where <Node Number> is any of the node addressing modes (list position, serial or
RepeaterID).
An ACCESS NODE session can always be aborted using the escape sequence
Wait 1 s, three dash within one second and Wait 1 s, which will bring the standard
userprompt back.
However, if logging in is completed into the remote node it is recommended to
perform a logout from the remote node instead. Otherwise the remote node might
stay logged in and cause the node to be unavailable for a while.
Note 1! ACCESS NODE is only available from master nodes to system slaves.
Note 2! When having direct access to a system slave, no communication will occur
to slaves on the same bus, meaning that no alarms will be monitored in the system
until logged out from the system slave.
Example of an ACCESS NODE session
AVITEC AB>access node 2
Use escape sequence <Wait 1s>---<Wait 1s> to abort.
Entering Direct Access mode.
