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 PCA in the instrument that was previously the last
instrument in the chain.
3. Close the instrument.
4. Using straight-through, DB9 male DB9 Female cable, interconnect the host and the analyzers as
shown in Figure 8-4.
5. BEFORE co
mmunicating from the host, power on the instruments and check that the Machine ID code is
unique for each. (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 key below the
corresponding digit to be changed).
NOTE
Teledyne API recommends setting up the first link, between the Host and the first instrument and testing
it before setting up the rest of the chain.
