3. Check that the following cable connections are made in all instruments (again refer
to Figure 3-19):

J3 on the Multidrop/LVDS PCA to the CPU‟s COM1 connector

(Note that the CPU‟s COM2 connector is not used in Multidrop)

J4 on the Multidrop/LVDS PCA to J12 on the motherboard

J1 on the Multidrop/LVDS PCS to the front panel LCD

(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 3-20, 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, and 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.
