11. Managing Machine Control Ports
Setting Machine Control Take Preferences
3 From the menu bar, select ‘Window > Machine Control Port Setup’. The ‘Machine Control Port
Setup’ window appears displaying current port settings, as shown in Figure 11-1 on page 102.
4 As needed, update the number in the ‘Take Delay’ field to set the frame ‘take’ delay. The “take
delay” is the number of video frames between the time a port is disconnected from one device
and connected to another. The delay period should be long enough to allow devices to recognize
that they have been reconnected to a new device, usually 20 to 30 frames. Be sure to verify that
the delay is sufficient
5 In the right-hand pane, select the ports being updated.
6 Update settings for the selected outputs by checking or unchecking the check boxes as
described in step 7 in Setting Up Machine Control Ports on page 101.
7 Click
Write
to send your changes to the control card.
8 Repeat steps 2–7 for each control card being updated.
Setting Machine Control Take Preferences
Using the UniConfig ‘Connections’ window, options for how machine control port ‘takes’ are per-
formed can be set. Because machine control ports are bi-directional, you can set in which direction
the ‘take’ occurs. Directions of signals are based on whether a device is set as a Controlling or Con-
trolled device in the ‘Machine Control Port Setup’ window. For more information, see
Setting Up
Machine Control Ports on page 101.
For information on setting other ‘Connections’ window preferences, see Setting ‘Connection’ Win-
dow Preferences on page 87.
‘Takes’ can be configured to perform as follows:
• Forward — Configures the router to perform a ‘take’ by sending signals from the Controlling
device to the Controlled device.
• Reverse — Configures the router to perform a ‘take’ by sending signals from the Controlled
device to the Controlling device.
• Broadcast — Configures the router to perform a ‘take’ by sending signals from the Controlling
device to multiple Controlled devices. One signal can be “broadcast” to several devices. For
more information, see
Broadcasting Machine Control Signals on page 112.
• Data X/Y — Configures the router to act as if machine control ports are standard I/O ports and
not bi-directional. See “About Data X/Y Takes” on this page .
About Data X/Y Takes
Machine control routers have bi-directional port; every port can pass both input and output signals.
X/Y routers have single direction ports; a port can either pass an input or an output signal, but not
both.
When a ‘take’ is performed in an X/Y router, for example input 1 to output 2, only one signal is
passed through the router from 1 to 2. When a ‘take’ is performed for port 1 to port 2 in a machine
control router, two signals are passed through: from 1 to 2 and from 2 to 1. Additionally, if a
another ‘take’ occurs, for example, for port 1 to port 4, the router passes signals 1 to 4 and 4 to 1
removing the signal path connections associated with port 2.
