6.11.SETUP  MORE COMM: Using the Analyzer’s Communication Ports

The GFC 7000TA is equipped with an Ethernet port, a USB port and two serial communication (COMM) ports located on the rear panel (Figure 3-2). Both com ports operate similarly and give the user the ability to communicate with, issue commands to, and receive data from the analyzer through an external computer system or terminal.

By default, both com ports operate on the RS-232 protocol.

∙The RS232 port (used as COM1) can also be configured to operate in single or RS-232 multidrop mode (option 62; See Section 5.5.2 and 6.11.7).

∙The COM2 port can be configured for standard RS-232 operation or half-duplex RS-485 communication (For RS-485 communication, please contact the factory).

A code-activated switch (CAS), can also be used on either port to connect typically between 2 and 16 send/receive instruments (host computer(s) printers, data loggers, analyzers, monitors, calibrators, etc.) into one communications hub. Contact Teledyne Instruments sales for more information on CAS systems.

6.11.1. Analyzer ID

Each type of Teledyne Instruments analyzer is configured with a default ID code. The default ID code for all GFC 7000TA analyzers is 360. The ID number is only important if more than one analyzer is connected to the same communications channel such as when several analyzers are on the same Ethernet LAN (See Section 6.11.6); in a RS-232 multidrop chain (See Section 6.11.7) or operating over a RS-485 network. If two analyzers of the same model type are used on one channel, the ID codes of one or both of the instruments needs to be changed.

To edit the instrument’s ID code, press:

The ID number is only important if more than one analyzer is connected to the same communications channel (e.g., a multi-drop setup). Different models of Teledyne Instruments analyzers have different default ID numbers, but if two analyzers of the same model type are used on one channel (for example, two GFC 7000TA’s), the ID of one instrument needs to be changed.
