Machine Control
When configuring the RCP-ME, you have the option to enable Machine Control, and to add a Machine Control
button to the panel.
What is Machine Control?
Typically, the ports on a data router (such as the NK-M series routers) are bi-directional where there is both a
transmit (input to output) and reciprocal receive connection that is made for each port. For example, a switch from
port 1 to port 2 involves a forward path (from port 1 input to port 2 output) and the reciprocal connection from (port
2 input to port 1 output).
In some cases however, there is a need to connect on the port’s input to several ports’ output (e.g. one device
commanding many target devices) without making the reciprocal connection. This allows the commanding device
to just broadcast commands and not receive from the many devices it communicates with.
Setting Up Machine Control
If your routing switcher system uses a machine control routing switcher to provide reciprocal switching of RS-422
signals, your RCP-ME must be set up to handle these switches. Machine control must be enabled in the RCP-ME
and the router level used for machine control must match that set in the machine control routing switcher.
To set up machine control
1. Open the RCP-ME Panel Config interface (see “ To open the RCP-ME Panel Config interface ” on page 22).
2. Select the Configuration tab.
3. In the Configuration section, select the Machine Control Enabled check box.
4. Use the Machine Control Level box to enter or select the machine control level to match the level that the
machine control routing switcher has been assigned.
5. Send the current configuration file to the device (see “ To send the current configuration to a panel ” on
page 74).
Assigning a Machine Control Button
If your master device controls multiple slave devices, you need a machine control button to temporarily disable
reciprocal switching until the last slave device is routed.
To assign a machine control button
1. Open the RCP-ME Panel Config interface (see “ To open the RCP-ME Panel Config interface ” on page 22).
2. On the simulated RCP-ME, select the button that you want to use for machine control.
The Button configuration box opens.
3. In the Button list, select Function Key .
4. Use the Value list to select MC Key .
5. Close the Button configuration box.
The simulated RCP-ME in DashBoard shows MC KEY on the selected button.
6. Send the current configuration file to the device (see “ To send the current configuration to a panel ” on
page 74).
