Figure 2-11. 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 and 22 of
JP2 on the Multidrop/LVDS PCA in the instrument that was
previously the last instrument in the chain.
4. Close the instrument.
5. Referring to Figure 2-12 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
internally wired specifically for RS-232 communication; see Figure 2-10).
