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)
