The Personal Computer (PC) is the most advanced diagnostic tool available for troubleshooting the V-MAC II system. In addition to performing all the functions of the Pro-Link 9000, it allows enhanced system diagnostics. The personal computer also permits information specific to the vehicle to be entered and stored in the V-MAC II module’s internal memory, and provides more flexibility in password selection. Any 100% IBM-compatible computer will work with the system. In order to connect a computer to the vehicle, a serial link interface is required. The ATA serial link adapter (part No. J 38351 or J 38351-B) or the Pro-Link 9000 can be used as the interface device. In addition, the V-MAC II SERVICE DIAGNOSTICS software package MUST BE loaded. This software package, as well as complete instructions for installing and running the program, is available through your MACK distributor. Be sure to follow the instructions completely.

The J 38500-63 serial link jumper should be used with both the J 1708 Serial data link adaptor and the Pro-Link. The jumper provides the ability to turn the V-MAC II system ON without having to turn on the key. This is not only convenient for programming, but is also very important for diagnostic troubleshooting.
