ISIS Intelligent Multiplex Wiring System

Here's a more conventional Mastercell installation in a classic Mustang, underneath the dash and directly above the transmission tunnel. This is a much better installation for a car that's going to be daily driven. The Mastercell input unit is rated up to an 85-degree (Centigrade) environment. You can also see the front Powercell adjacent to the Mastercell.

Here's a typical rear Powercell installation. This unit is set up in the trunk to control the rear electrical demands of this project. You're looking at the whole shooting match with all taillights, brake lights, turn signals, and license plate lamp, plus the fuel pump, wired into the Powercell. Commands from the Mastercell come in one end of the box and the result goes out the other end. It's that simple. After situating your master and power cells just plug in the power cables and complete the connections to the loads. Once the installation is complete the system tests itself to make sure everything is working. If you have any problems an applications expert at ISIS is available to help you troubleshoot your system. They can take you through the process step by step to make sure that you've got everything properly installed.

For instantaneous system monitoring, the ISIS inSIGHT diagnostic module is now standard with both the 2-Cell and 3-Cell starter kits. With it, you can ensure that your electrical system is functioning normally and that all electrical connections are intact. It comes already installed into the Mastercell input unit and you'll instantly see the status of every power output connected to the system. This diagnostic tool displays information on a back-lit, high-intensity blue screen. The four-line, 16-character display is easy to read in all light conditions. It allows for simple and quick diagnostics and troubleshooting of the system installation. The instantaneous indications allow for quick testing of electrical functions for all inputs. Real-time monitoring of critical parameters for all cells in the system gives you continuous access to automobile electrical system status.

This photo shows the available inLINK remote control option that's available with the ISIS system. It's similar to traditional key fobs in form but offers much more in the way of function. It allows you to control all of the electrical functions on your vehicle from a distance of up to 150 feet away. To use inLINK, simply press the button to send a message to the Mastercell input unit. Just as when a switch is flipped inside the car, the specified output is then turned on in the Powercell control unit. The fob has four pages of functions. Page one includes enable security, disable security, operate headlights, and operate parking lights. The security function doesn't lock the doors. Rather, it disables the ignition and starter in the car via the Mastercell, thus protecting the vehicle from thieves. Any output can be tied to the security function, locking it out unless it's unlocked via inLINK. When activated, the lights on the car will flash a short pattern. When disabled the lights will flash a different pattern. Security will not enable when the ignition is on. The second page includes close lock, open lock, plus two other selectable functions. Page-three functions include ignition, four-way flashers, fan override, and panic button. When pressed, the panic switch function will sound the horn in a loud pattern until the button is pressed again to turn it off. Page four fob functions are all open to your selection. Thus the four-buttoned fob offers a total of 16 possible commands. The optional inLINK RF control module costs $179.
