6.2.3. COM PORT TESTING 

The serial ports can be tested for correct connection and output in the COMM menu. 
This test sends a string of 256 ‘w’ characters to the selected COM port. While the test is 
running, the red LED labeled TX for that COM port on the instrument’s rear panel 
analyzer should flicker.  

To initiate the test, access the COMMUNICATIONS Menu (SETUP>MORE>COMM),

The RS232 and COM2 communications (COMM) ports operate on the RS-232 protocol 
(default configuration). Possible configurations for these two COMM ports are 
summarized as follows:   

  RS232 port can also be configured to operate in single or RS-232 Multidrop mode 

(Option 62); refer to Sections 3.3.1.8 and 5.7.1. 

  COM2 port can be left in its default configuration for standard RS-232 operation 

including multidrop, or it can be reconfigured for half-duplex RS-485 operation 
(please contact the factory for this configuration).  

Note that when the rear panel COM2 port is in use, except for multidrop 
communication, the rear panel USB port cannot be used. (Alternatively, when the USB 
port is enabled, COM2 port cannot be used except for multidrop).
