Machine Control
Machine Control
Machine control ports can be configured with the following port types. All of these are variants
on controlling and controlled:
•
Controlling
Declares that the port connects to a device that normally functions as a controlling device
(but may also serve as a controlled device).
•
Controlled
Declares that the port connects to a device that normally functions as a controlled device
(but may also serve as a controlling device).
•
Dynamic
Declares that the port type can change to match the requirements of the current operation.
The changes take place under the direction of the router control system.
Note: This is both the default and the recommended setting for most applications.
•
DTE
Declares that the port connects to a controlling device. This port type is used only in RS-232
applications.
•
DCE
Declares that the port connects to a controlled device. This port type is used only in RS-232
applications.
•
Master
Declares that the port connects to a primary (or master) device. A dynamic port that is
routed to or from a master port becomes a slave port.
•
Slave
Declares that the port connects to a secondary (or slave) device. A dynamic port that is
routed to or from a slave port becomes a master port.
By default, all machine control ports are set to ‘Dynamic’.
Machine Control Partitions
The routers that support machine control (the NV5128 and the NV5256) have 4 machine control
partition types:
Reverse
Forward
Broadcast
Data X/Y
Reverse is the default because it is the most commonly applicable.
It is in the ‘Partitions’ window that you can configure a machine control partition as one of the
following types:
•
Forward
Signals flow from the controlling device to the controlled device.
•
Reverse
Signals flow from the controlled device to the controlling device.
•
Broadcast
Allows the router to send signals from the controlling device to multiple controlled devices.
