BCS Control
Enter the following BCS command for the example in FIG. 101.
CL0I2O1 3 4T
In this command, a controller signal is routed on Level 0 from X-Port 2 to Y-Ports 1, 3, and 4. The last
device status signal returned (from Y-Port 4) is the only status device signal that remains connected. If
the remaining device status signal must be returned from a different Y-Port, simply change the order the
Y-Ports are entered in the command. The remaining device status signal will be the last one entered.
Switching Independent Controller and Device Status Signals
To switch controller and device status signals independently, commands are executed using different
levels (virtual matrices). This method can be used for either of the configuration methods, as long as
each signal type is on a different level. The system must be configured in XNConnect to handle this type
of independent routing. If the system was not ordered this way, contact technical support (see page 43).
Control Panel
When routing controller and device status signals independently with a control panel, be sure to change
the level prior to each Change command.
BCS Control
The following example assumes an X to Y Point-to-Point configuration in which Level 1 has been
configured to route only the X-Port's controller signals and Level 2 has been configured to route only the
Y-Port's device status signals.
CL1I5O6T
CL2I5O7T
In the first command, a controller signal is routed on Level 1 from X-Port 5 to Y-Port 6 without a device
status signal being returned from Y-Port 6 to X-Port 5.
In the second command, the device status signal for Y-Port 7 is routed on Level 2 to X-Port 5 without a
controller signal first being routed from X-Port 5 to Y-Port 7.
