Extron electronic MLC 62 RS EU, MLC 62 RS MK setup guide Connect and apply power

zz Digital Input port — Connect a switch or sensor to this port to control other devices in the room that are connected to the MLC serial, IR, or relay ports. The port monitors the high and low states of the connection between the switch or sensor

Two-position Switch

and the connected device. For the voltage thresholds, a voltage below 1.0 VDC is considered logic low, and a voltage above

1.5VDC, logic high. When a threshold between the states is crossed (from high to low and vice versa), the selected action occurs.

By default, this port is configured with a +5 VDC pull-up resistor for use with basic non-powered switches. If the device being connected has its own power source, configure the port to disable the pull-up mode (see the configuration program help file for port setup procedures). To

7.Configure the MLC buttons and ports (see the MLC 60 Series Configuration Program Help File for the procedures).

a.Load and install the configuration software to your computer from the Extron website or the provided DVD.

b.Obtain device drivers. Drivers for the devices that will be connected to the MLC rear panel IR and serial ports can be obtained from the provided MLC software DVD or downloaded from the Extron website at www.extron.com. You can also obtain them using the configuration software if an Internet connection is available.

c.Upload the configuration to the MLC.
