CHAPTER 2
GETTING ONLINE
Now that your Haltech E6H/E6M 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 E6H/E6M ECU you will need the programming cable and
programming disk supplied.
2.1 Connecting the Haltech E6H/E6M to a Computer
The programming cable supplied with the Haltech E6H/E6M 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 E6H/E6M 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.
You may now connect the Ignition Sub-Loom to the main wiring loom
2.2 Operating the Software
2.2.1 Computer Requirements
The computer required to program the Haltech E6H/E6M 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 programs), 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).
