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 communicating 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 recommends setting up the first link, between the Host and the first instrument and testing it

before setting up the rest of the chain.
