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 Sections 3.3.1.9 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).
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 TAI Sales
for more information on CAS systems.
To assist in properly connecting the serial ports to either a computer or a modem, there
are activity indicators just above the RS-232 port. Once a cable is connected between
the analyzer and a computer or modem, both the red and green LEDs should be on.
•
If the lights are not lit, use small switch on the rear panel to switch it between DTE
and DCE modes.
