4.11.3. RS-485 Configuration of COM2

4.11.4. DTE and DCE Communication

07272B DCN6552
As delivered from the factory, COM2 is configured for RS-232 communications.
To configure this port for RS-485 communication, please contact the factory. If
COM2 is configured for RS-485, the USB com port is no longer enabled.
RS-232 was developed for allowing communications between data terminal
equipment (DTE) and data communication equipment (DCE). Basic terminals
always fall into the DTE category whereas modems are always considered DCE
devices. The difference between the two is the pin assignment of the Data
Receive and Data Transmit functions. DTE devices receive data on pin 2 and
transmit data on pin 3; DCE devices receive data on pin 3 and transmit data on
pin 2.
To allow the analyzer to be used with terminals (DTE), modems (DCE) and
computers (which can be either), a switch mounted below the serial ports on the
rear panel allows the user to switch between the two functions.
