Figure 3-14:
Note: If you are adding an instrument to the end of a previously configured chain,
remove the shunt between Pins 21 ↔ 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 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.
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 Section 3.3.1.8 under "RS-232 Connection".
7. BEFORE communicating from the host, power on the instruments and check that
the Machine ID code is unique for each (Section 5.7.1).
a. In the SETUP Mode menu go to SETUP>MORE>COMM>ID. The default ID is
typically the model number or "0".
