PAC VS41 Intelligent 4 Camera Switcher Instruction Manual

PAC VS41 Intelligent 4 Camera Switcher Instruction Manual

Introduction & Features

The VS41 is an intelligent 4 camera switcher for controlling front, rear, and blind spot cameras. Manually connect cameras and trigger wires (pulsed or constant inputs), or connect to a BCI-, RP4.2-, or RPA- module’s expansion port for full digital control, and fast easy connectivity. The VS41 also accepts analog + or – and constant / pulsed signals.

Important Notes

1. If you are using the VS41 with another PAC interface, such as a BCI-, RP4.2-, or RPA-, with an Expansion Port, simply connect the 10-pin connector into the module. Do not manually wire the positive or negative trigger wires. The BCI-, RP4.2-, or RPA- module will digitally control the VS41 switching operation when connected to the Expansion Port.
2. The VS41 video output will always default to the signal from Input 1 when none of the input triggers are activated. This Input is ideal for connecting the rear (reverse) camera.
3. The VS41 inputs have priority in descending numerical order. For example: If you have Input 3 or 4 triggered, then you trigger a lower number input (for example Input 2), Input 2 will take priority over the higher numbered Input.
4. The input triggers can accept either a pulsed or constant input, making them ideal for connecting to a turn signal as a trigger.
5. The reverse trigger output will provide a 150 mA 12v (+) trigger while any of the input triggers are activated.
6. Upon deactivation of the last positive or negative trigger, the last video input source and the reverse trigger output will remain active for an additional 3 seconds. (Not applicable when used with a BCI-, RP4.2-, or RPA- interface).
7. If there is poor video quality after installation of this module, please ensure quality connections on any RCA connections.
8. Positive Input triggers accept input voltages in the range of 2v to 12v.

Introduction & Features

The VS41 is an intelligent 4 camera switcher for controlling front, rear, and blind spot cameras. It is designed to be used with PAC radio replacement interfaces.

Important Notes

1. aftermarket radio in the following vehicles:
   • 2003-2006 GM Trucks / SUVs
2. You must locate and connect to the analog turn signal wires in the vehicle, as well as connect the reverse output trigger from the GM1A to the VS41. Please wire the VS41’s analog input triggers 1, 3 and 4 according to the instructions below.
3. Analog input trigger 2 on the VS41 only needs to be connected if you want manual activation of the front camera via toggle switch. Automatic activation of the front camera (Input 2) via Class II Data-Bus commands can be set using the Radio PRO PC application. See page 2 for more details on the Radio PRO PC app.
4. The reverse trigger output will provide a 150 mA 12v (+) trigger while any of the input triggers are activated.
5. The VS41 video output will always default to the signal from Input 1 when none of the input triggers are activated. This Input is ideal for connecting the rear (reverse) camera.
6. The VS41 inputs have priority in descending numerical order. For example: If you have Input 3 or 4 triggered, then you trigger a lower number input (for example Input 2), Input 2 will take priority over the higher numbered Input.
7. If there is poor video quality after installation of this module, please ensure quality connections on all RCA connections.

Installation Steps

1. Connect the 10-pin expansion plug to the GM1A interface.
2. Wire up all the triggers and inputs as indicated in the chart on page 1.
3. See diagrams below for location of turn signal wires.
4. Once connected, verify all cameras are showing properly. The front camera behavior can be setup using the Radio PRO app.
   Please see the next section for more details on the Radio PRO app.
   

Radio PRO App

Use of the Radio PRO App allows you to do the following:

• Set the behavior of the front camera

Connect the GM1A interface to the PC and select the behavior of the front camera. Use the chart below to understand how each mode works. The GM1A does not have to be connected to power or in the vehicle to access camera settings.

whenever the vehicle is going faster than 0 mph or less than the designated number.| *Options are: 3 mph, 5mph, or 7 mph.
On when Shift into D until 6MPH or 30Sec| This will activate the camera input whenever the vehicle is placed into Drive. The camera input will turn off once the vehicles speed is faster than 6MPH, or after 30 seconds.| This mode should be used in vehicles that have an automatic transmission
On when Shift out of R until 6MPH or 30Sec| This will activate the camera input whenever the vehicle is shifted out of reverse. The camera input will turn off once the vehicles MPH is faster than 6MPH, or after 30 seconds.| This mode should only be used in vehicles that have a _manual _transmission.

Technical Bulletin

Issue:
When engaging the brakes or turning on the parking lights, the VS41 falsely triggers the blind spot cameras.

Solution:
Wire a resistor with a value between 40k Ω – 60k Ω in series with the analog trigger wire corresponding with the camera having the false trigger issue. This should be inputs 3 and / or 4 as these are the designated blind spot camera inputs. Follow the wiring diagram below to correct the issue

Important Notes:

• This only applies to V7 or lower hardware. If you have V8 hardware this problem should not be present as this resistance has been added to the circuit internally.
• Resistors only need to be added to the wires that are being triggered.
