•
Valve Close: To force the valve closed, connect the black (pin 12) wire to one of the analog grounds.
•
Purge: To force the valve to its maximum open position which we call “Purge,” connect pin 4 to pin 11.
Note that this will allow much greater flow than the rated full-scale value.
2.7 Configuring Your Instrument
The MaxTrak instruments have many features which can be changed by the user. You may wish to review these
features and modify some of them prior to operation of your instrument. This must be accomplished using Digital
Communication with the supplied SmartTrak software. If you prefer to use your instrument as delivered, please
proceed to Chapter 3: Analog Operation.
2.7.1 Using SmartTrak Software to Configure Your Instrument
You can communicate with your instrument using the SmartTrak Software package (provided with your purchase)
and your PC running the Windows operating system. Simply connect the purple (pin 7) wire, the pink (pin 13)
wire and one of the analog grounds: brown, orange or gray wires (pin 1, 3, or 10) to a standard DB-9 connector
according to the chart on the next page.
RS-232 Wiring Configuration
RS-232 Transmit (pin 7) To DB-9 pin #2
RS-232 Transmit (pin 13) To DB-9 pin #3
Analog Ground (pin 1,3, or 10) To DB-9 pin #5
With the connections above in place, plug the DB-9 connector into an appropriate serial port on your PC. If you are
in an environment with high RF interference, it may be necessary to shield these wires. Should your computer not
have a serial port, you will need a serial to USB adapter. See Chapter 4 for details.
You are now ready to configure your MaxTrak instrument. Proceed to Chapter 4 for a discussion of the use of the
SmartTrak software
