Teledyne gfc 7000ta operation manual 29 RS-232 Communication Parameters for Hessen Protocol

Operating Instructions Model GFC7000TA Carbon Dioxide Analyzer

6.15.4.2. Hessen com Port Configuration

Hessen protocol requires the communication parameters of the GFC 7000TA’s com ports to be set differently than the standard configuration as shown in the table below.

Table 6-29: RS-232 Communication Parameters for Hessen Protocol

Parameter	Standard	Hessen
Data Bits	8	7
Stop Bits	1	2
Parity	None	Even
Duplex	Full	Half

To change the rest of the com port parameters. See Section 6.11.5.

To change the baud rate of the GFC 7000TA’s com ports, See Section 6.11.8.

NOTE

Make sure that the communication parameters of the host computer are also

properly set.

Also, the instrument software has a 200 ms. Latency before it responds to

commands issued by the host computer. This latency should present no problems,

but you should be aware of it and not issue commands to the instrument too

frequently.
