Bias Mode
Bias mode is useful for connecting the same input to multiple channels (output
ports) simultaneously. And the connections will be kept until the other input port
connection will be changed.
When the bias mode is ON, the input bias port is connected to all bias enabled
output ports that are not connected to any other input ports. You cannot directly
control which output ports are connected to the input bias port:
• If another input port is disconnected from a bias enabled output port, the output
port is automatically connected to the input bias port.
• If another input port is connected to a bias enabled output port, the output port is
automatically disconnected from the input bias port.
• Bias disabled output ports are never connected to the input bias port when the
bias mode is ON.
• You can independently set the bias port and control the bias mode for each
module when the configuration mode is normal.
When the bias mode is OFF, the input bias port is the same as the other input ports,
so relays can be controlled directly to connect to output ports.
Figure 3-1 shows an example. Input 2 is the input bias port. When the bias mode is
turned ON, all bias enabled output ports (that are not connected to other input ports)
are connected to the input bias port. So, the output ports that are connected to input
port 1 and 3 are not connected to the input bias port.
