Teledyne M300EM operation manual Host, Calibrator, TAPI Analyzer, Last INSTRUMENT, is installed

Teledyne API – Technical Manual - Model 300E Family CO Analyzers Remote Operation

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 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.
