12/1/99 Introduction The 2-Channel Model GF868 flowmeter cannot provide accurate flow rate measurements for either channel until the instrument has been properly installed, the channel has been activated, and the basic system and pipe parameters have been programmed into the meter.
12/1/99 Using the Keypad The Model GF868 keypad contains 39 keys, which are labeled with their primary (unshifted) functions. In addition, pressing the red key will access the secondary functions assigned to most of [SHIFT] the keys. The complete keypad is illustrated in Figure 1-1 below and a detailed description of both the unshifted and shifted functions for each of the 39 keys is listed in Table 1-1 on page 1-3.

Note: The available options at this prompt are: 5sec, 10sec, 30sec, 1min, 3min, 6min, 12min, 30min and 60 min. The time increment is the frequency at which the Model GF868 takes and records data measurements. If any reading takes longer than the programmed time increment, the log is filled in with the next consecutive reading.

• 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.
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/change the baud rate setting of the GF868, proceed as follows: Access the User Program, by pressing the [PROG] key on the keypad.
Using the Settings Menu, select the Communications option. 3. When the Communications Screen appears, make the following selections: • Baud Rate - set to the same value as the GF868 setting • Data Bits - 8 • Stop Bits - 1 •...
To set up serial communications with a Systems personal computer running under Windows 95, Windows 98 or Windows NT, make sure the GF868 is powered on and complete the following steps: 1. From the Windows START menu, select PROGRAMS>...

Point-To-Point Wiring Standard factory wiring of the RS485 serial interface is configured for point-to-point wiring. That is, a single Model GF868 may be wired directly to a single personal computer. To connect the RS485 serial interface, refer to Figure 6-1 on page 6-5 and complete the following steps: Note: For compliance with the European Union’s Low Voltage...
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.
