Figure 4-9: Jumper and Cables for Multidrop Mode
Note: If you are adding an instrument to the end of a previously configured chain,
remove the shunt between Pins 21

22 of the Multidrop PCA in the instrument
that was previously the last instrument in the chain.
4. Close the instrument.
5. Referring to Figure 4-10, 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.
6. On the rear panel of each analyzer, adjust the DCE DTE switch so that the
green and the red LEDs (RX and TX) of the COM1 connector (labeled
RS232) are both lit. (Ensure you are using the correct RS-232 cables that are
internally wired specifically for RS232 communication).
