CHANGING POINT-TO-POINT TO MULTI-POINT
1. Determine the multipoint base, should be the device connected to the PCL or ORB, change
Dip Switches 5 and 6 to the OFF position.
2. All other units will be considered multipoint remote units; change Dip Switch 5 to OFF and
Dip Switch 6 to ON.
3. Serial cable should be wired, and power has also been wired and turned on.
4. Ensure the Power Indicator LED light is solid red and that Serial Data In/Out LEDs are flashing.
