530T Window Automation System  
The 530T window automation system controls the operation of two vehicle windows in both the up and down  
directions. The 530T automatically rolls up the power windows when the security system is armed, as well as pro-  
viding “one-touch” operation in either direction. The 530T can also be used to vent or roll the windows  
completely down with an auxiliary channel from the security system.  
Identifying Window Systems  
Before wiring the 530T, it is important to understand how different window systems work. A 12VDC motor must  
have (+)12V on one of its wires and (-) chassis ground on the other in order for it to operate. Most window  
switches are connected directly to the window motor with two wires. These two wires will either rest at (-)  
ground, (+)12V ignition, or sometimes they will rest open. In any of these systems, the switch, when activated,  
will send (+)12V to one wire and (-) ground to the other wire. Which wire gets (+)12V and which wire gets (-)  
ground determines which direction the motor will roll the window.  
The three window systems will be referred to in this manual as type A, B, or C. To determine which type of system  
you have, turn the ignition on, check the power window wires at the switch with a meter to see what polarity  
they rest at. If they rest at (-) ground, you have a type A system. This is the most common system. If they rest  
at 12V when the ignition is on, you have a type B system. This system is used on many European vehicles. If the  
wires rest open, you have a type C system. The wiring for the type A and type C systems is exactly the same,  
however, the type B system differs slightly.  
NOTE: If the vehicle is equipped with any type of factory automatic full-travel or “one-touch”  
system on the driver’s window, there may be a relay or module in the driver’s door. Be sure to inter-  
face with the wires between the module and the window motor.

Type B Windows  
Some window systems use either a central control module, or control modules in each door. These systems are  
less common than direct wired systems. These can be found in many newer Volkswagens, BMWs, Isuzus, Maximas  
and Grand Cherokees. If the vehicle has one of these systems, the 530T must be interfaced between the module(s)  
and the window motor(s). This often requires the wires to be run into each door. The 530T monitors the AC  
“noise” generated by the motion of the motor. For this reason the 530T cannot drive relays or control modules  
in the system.

NOTE: If the security system does not have a ground-when-armed output, a negative lock pulse  
from the security system can be used to roll the windows up, as shown in the following diagram.  
H2/5 GRAY (-) Output During Activation: Connect this wire to an optional relay (P/N 610T) to bypass sensors  
which may trigger the security system during operation. This wire continues to output negative (-) ground for 5  
seconds after the window motors have stopped.

Dip Switch Settings  
The 530T uses internal resistors to change the amount of force required to drive the window motors. These resis-  
tors are controlled by a group of dipswitches on the side of the module. Some vehicles use very efficient motors  
and little force is needed. This would require the switches to be set to a low setting. Some newer imports, such  
as Honda Accords and Civics, may require a lower setting. Others use very inefficient motors, or the windows seem  
“harder” to roll up. Some examples would be older domestic cars, as well as many full-size pickups. These vehi-  
cles require the switches to be set to a higher setting.

Switch Input Polarity  
ON (-) OFF (+)  
Dipswitch #5 controls the polarity that the 530T switch input wires will respond to. For type A and type C  
systems, it must be set to the OFF (+) position. When the switch is in the off position the 530T responds to (+)  
positive inputs on its switch wires. If your vehicle has a type B system, this switch must be set to the ON (-)  
position, so the 530T will respond to (-) negative inputs on its switch wires. Remember, the type B system  
switches its wires to (-) ground rather than (+)12V.  
Mounting the Control Module  
When mounting the control module, always locate it as close to the window motor as possible. The driver-side kick  
panel is an ideal location. If “one-touch” operation from the passenger-side switch is desired, interface with the  
passenger-side wires between the passenger-side switch and the motor. This usually requires the passenger-side wires  
to be extended and run into the passenger-side door. When extending the wires, use no smaller than 14 gauge wire.  
IMPORTANT! Do not mount the control module in the vehicle door, as water damage will result. The  
best results are obtained by mounting the control module inside the vehicle, as close to the window  
motor as possible, in one of the kick panels.  
Operating Instructions  
To roll the windows up:  
Simply arm the vehicle security system. The windows will roll up completely.  
To arm the security system and leave the windows down:  
1. Press the auxiliary channel.  
2. Within 5 seconds arm the security system.  
3. The security system will arm, but the windows will remain down.  
To vent the windows:  
At any time, press and release the auxiliary channel. The windows will vent about two inches.  
To roll the windows down:  
At any time, press and hold the auxiliary channel for three seconds. The windows will roll all the way down.  
To activate “one-touch” operation:  
1. Turn on the ignition.  
2. Tap the power window switch in either direction. The window will open or close completely.  
To stop the window:  
1. Turn on the ignition.  
2. Tap the power window switch in either direction while the window is in motion.

NOTE: If “one-touch” operation is desired from the passenger-side switch, the passenger-side wires  
must be run into the passenger-side door and interfaced between the passenger-side switch and the  
motor.  
NOTE: If using a delayed auxiliary channel from the security system, such as channel 2, to control  
windows down operation, the transmitter button will need to be pressed for 1.5 seconds to vent  
the windows or 4.5 seconds to roll the windows all the way down.  
Troubleshooting  
The windows do not move, and the 530T fuse blows.  
The switch side and the motor side connections may be reversed. Always make these determinations while using  
the master switch (if there is one), and cut both wires before testing if any uncertainty exists.  
The window moves an inch or so, and stops.  
Does that window have a one-touch module? If so, make sure the wires are correctly interfaced at the motor and  
not at the switch.  
Is the window too efficient, or inefficient? If you help the window up does it move the entire direction? If so,  
the dipswitches must be set to a higher setting. If you apply pressure to the outside of the glass, does the  
window move the entire direction? If so, the dipswitches must be set to a lower setting.  
One window works fine, but the other doesn’t move.  
Does the window in question have a one-touch module? If so, make sure the wire connections were made between  
the module and the window motor.  
Try increasing or decreasing the resistance for that one window only (see Dipswitch Settings section of this  
guide). If that has no effect, try reversing the passenger- and driver-side wires. Has the problem now switched  
to the opposite window? If so, check the 530T. If not, double-check the switch side and motor side wire to be  
sure they are not reversed.  
How can I control a sunroof?  
We recommend using a 529T instead of a 530T.  
I can’t find any wires on the switch that seem to work.  
Some new vehicles use unusual window control modules. Many of these require the 530T wires to be run into  
each door. Some examples are listed below. If you are unsure, call DEI for details. The Nissan Maxima, Pathfinder,  
Volkswagen Corrado, Passat, Golf, Jetta, Honda Passport/Isuzu Rodeo and most BMWs are examples of vehicles  
with window control modules.
