APTER CONNECTORS Wiring The RS 232 is a point to point protocol and as such it specifies a two different wiring schemes depending on if you are originating the transmission or receiving the transmission In the original spec modems communicated with terminals and were wired as Data Communications Equipment or DCE Terminals or printers received data from modems and thus were wired as Data Terminal Equipment or DTE As technology has progressed it has become more ambiguous who was DCE and DTE Teledyne analyzers are wired as DTE i e like a printer As can be seen this presents difficulties if you a hook a printer to the instrument that is likewise wired as a printer To help understand the different problems 3 examples as shown below Example 1 Connecting the Teledyne API analyzer to an IBM PC AT compatible computer In this case the PC is wired as DCE and the analyzer is wired as DTE therefore a null modem is not needed The wiring is straight through i e pin 1 to pin 1 pin 2 to pin 2 etc Therefore all you have to do here is adapt the connector on the analyzer male DB 9 to whatever is on the PC Make sure none of the adapters have null modems in them Example 2 Connecting the Teledyne API analyzer to a serial printer In this case both the analyzer and the printer are wired as DTE so a Null Modem will have to be inserted in the line to change the wiring to make the analyzer look like a modem i e DCE

34. Point Calibration Multi point calibration requires seven approximately equally spaced calibration points including zero using an NIST traceable CO source The calibration must be carried out 1 After maintenance 2 Every three months recommended CAUTION The test gas must be introduced into the analyzer through the sample inlet port All flow measurement devices must be calibrated against an nist traceable standard such as a bubble flowmeter that has been calibrated against an nist traceable volume standard Teledyne API Model 300M CO Analyzer Instruction Manual 04033 Rev A 8 2 1 There are two acceptable methods of generating accurate CO concentrations for calibrating the Model 300M One method uses a single cylinder of CO in air and a means of accurately diluting the cylinder gas with zero air This is illustrated in Figure 8 1 Alternatively several cylinders of CO in air of appropriate concentrations may be used without dilution The cylinder concentrations must be traceable to NIST standards Flow correction for standard temperature and pressure STP is not required with either method With dilution the correction is self canceling With the multi cylinder method the correction is not applicable Procedure 1 Set the analyzer to the desired range 2 Setthe calibration system to deliver a flow of at least 1000 cc min The Model 300M draws approximately 800 cc min See Section 8 1 and Figure 8 2
