6.3. RS-232
The RS232 and COM2 communications (COMM) ports operate on the RS-232 protocol
(default configuration). Possible configurations for these two COM 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,
analyzers, monitors, calibrators, etc.) into one communications hub. Contact Teledyne
API Sales for more information on CAS systems.
To configure the analyzer‟s communication ports, use the SETUP>MORE>COM menu.
Refer to Section 5.7 for initial setup, and to Section 6.2 for additional configuration
information.
6.4. RS-485 (OPTION)
The COM2 port of the instrument‟s rear panel is set up for RS-232 communication but
can be reconfigured for RS-485 communication. Contact Customer Service. If this
option was elected at the time of purchase, the rear panel was preconfigured at the
factory.
