Teledyne 460L User Manual

The 460L comes equipped with a powerful digital Serial Communications Port that can be used for 
Data Acquisition and for changing the monitor’s configuration.  This port can be configured for 

either RS-232 or RS-485 (half-duplex) operation.  See Section 3.7.1 for details on configuring the 
port and connecting it to a computer or data acquisition system.
