CHAPTER 2
Getting Online
Now that your Haltech F9 is installed with all the sensors in place the system can be
connected to the programming computer. This will allow the readings from all the sensors to
be displayed on the screen and checked for correct operation.
To connect the PC to the Haltech F9 ECU you will need the programming cable and
programming disk supplied.
2.1 Connecting the Haltech F9 to a Computer
The programming cable supplied with the Haltech F9 is a standard serial link extension cable.
One end of the cable will plug into the Main Harness PC Interface connector (near the main
connector). The other end should plug into the mating connector at the back of your
computer. The plug on the computer may be marked "Serial", "Mouse" or "COM". Almost all
laptops will have this plug. If there is no 9 pin plug which it will connect to, check to see if
there is a 25 pin D-type plug available (some desk top computers will have this). If this is the
case, an appropriate cable can be supplied on request. Alternatively, most electronic retailers
will have a 25-pin to 9-pin converter.
Any time you wish to communicate with the F9 ECU it needs to be supplied with power. This
usually involves just turning on the ignition switch. If at any stage power is not on, or the
programming cable is disconnected while attempting to communicate, the programming
software will display the message RECONNECT HALTECH. To rectify this, reconnect
power and/or the programming cable.
2.2 Operating the Software
2.2.1 Computer Requirements
The computer required to program the Haltech F9 can be any IBM-PC compatible personal
computer from the XT onwards (i.e. the AT, 386, 486 or Pentium computers). The
requirements are fairly modest. The computer must have at least 640K of RAM (with about
590kb free for executable programmes), one 3.5" disk drive and a CGA, EGA, or VGA
screen. (Virtually all reasonably modern laptops running MS-DOS (version 5.00 or higher)
will fit this description).
2.2.2 Installing the Software.
The Programming Disk supplied with the Haltech F9 has an installation programme that
allows you to install the software onto the PC’s Hard Disk. Most modern PCs have a hard
disk. If your PC does not have a hard disk, the F9 Programme can ran directly from the disk
