SERIAL CABLE  WIRING DIAGRAMS 

The serial port on the LecNet device is a minimal RS-232 implementation.  The figure shows the wiring diagram to 
accommodate interconnection with either a 9 or a 25 pin serial port on a PC or other serial device.

AMX Programming Notes 

If you are using an AMX system to control your LecNet 
equipment, you’ll want to purchase the Lectrosonics PT3 
Protocol Translator.  The PT3 connects between the AMX 
bus and any LecNet equipment.  With the PT3, the LecNet 
equipment looks just like native AMX equipment.  The 
PT3 is the fastest and most productive way to control 
LecNet devices with an AMX system.
