3. Close the instrument.
4. Referring to Figure 3-15 use straight-through DB9 male  DB9 female cables
to interconnect the host RS232 port to the first analyzer’s RS232 port; then
from the first analyzer’s COM2 port to the second analyzer’s RS232 port; from
the second analyzer’s COM2 port to the third analyzer’s RS232 port, etc.,
connecting in this fashion up to eight analyzers, subject to the distance
limitations of the RS-232 standard.
5. BEFORE communicating from the host, power on the instruments and check
that the Machine ID code is unique for each (Section 5.7.1). On the front panel
menu, use SETUP>MORE>COMM>ID. Note that the default ID is typically
the model number; to change the 4-digit identification number, press the button
of the digit to be changed).
Note Teledyne Analytical Instruments recommends setting up the first link,
between the Host and the first analyzer, and testing it before setting up
the rest of the chain.

RS-485 Connection
As delivered from the factory, COM2 is configured for RS-232 communications. This
port can be reconfigured for operation as a non-isolated, half-duplex RS-485 port. Using
COM2 for RS-485 communication disables the USB port. To reconfigure this port for
RS-485 communication, please contact the factory.
