Operating Instructions

Model GFC7000TA Carbon Dioxide Analyzer

6.15.2.6. Remote Access by Modem

The GFC 7000TA can be connected to a modem for remote access. This requires a cable between the analyzer’s COM port and the modem, typically a DB-9F to DB-25M cable (available from Teledyne Instruments with part number WR0000024).

Once the cable has been connected, check to make sure the DTE-DCE is in the correct position. Also make sure the GFC 7000TA COM port is set for a baud rate that is compatible with the modem, which needs to operate with an 8-bit word length with one stop bit.

The first step is to turn on the MODEM ENABLE communication mode (Mode 64, Section 6.11.5). Once this is completed, the appropriate setup command line for your modem can be entered into the analyzer. The default setting for this feature is

AT Y0 &D0 &H0 &I0 S0=2 &B0 &N6 &M0 E0 Q1 &W0

This string can be altered to match your modem’s initialization and can be up to 100 characters long.
