6.2.3. COMM 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 on the rear panel of the analyzer should flicker.
To initiate the test press, access the COMMUNICATIONS Menu (refer to Figure 5-13),

6.3. RS-232
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 Section 3.3.1.8.
 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)
A code-activated switch (CAS), can also be used on either port to connect typically
between 2 and 16 send/receive instruments (host computer(s) printers, data loggers,
