  • Transfer the log files to the personal computer. Wiring the RS232 The first step is to connect the built-in RS232 port in the GF868 to one of the serial ports (COM1 or COM2) on the personal computer. Interface Table 6-1 below lists the standard cables available from Panametrics for this purpose.

• Page 128: Setting Up The Terminal Software

  For successful serial communications, the GF868 and the personal computer must be set up to send/receive data at the same speed. To Baud Rate verify or change the baud rate setting of the GF868, proceed as follows: Access the User Program, by pressing the [PROG] key on the keypad.

  12/1/99 Multi-Point Wiring The standard point-to-point wiring configuration for the serial interface converter may be modified to permit the use of a multi-point wiring arrangement. In a multi-point RS485 system, one flowmeter (the master) is connected to the personal computer, while a number of additional flowmeters (the slaves) are chained together and connected to the master flowmeter.
