The Proxicam Enhancement Box (PXE) is an advanced in-line I/O controller that enables intelligent system logic such as Safe-to-Approach and Dynamic Detection. By configuring specific hardware modes via dip switches and correctly mapping the machine's control signals, technicians can define exactly how the system interprets the vehicle's state to automatically mute irrelevant camera feeds or suppress external output triggers.
Key Specifications
- Supply Voltage: 12V - 85V DC.
- Trigger Output Current: 500mA per channel.
- AUX, FWD/Mute Input Voltage: 9V - 85V DC.
- Waterproof Rating: IP66.
- Operating Temperature: -40°C to +85°C.
Configuration and Usage: Modes and Connections
-
Access the Mode Selector:
Remove the watertight rubber boot from the side opening of the PXE module to expose the physical 3-position dip switches. -
Select the Hardware Logic Mode:
Set the dip switches to match your required operational logic.-
MODE 1 (Default / Pass-through):
Operates as a standard continuous system. Alerts and outputs for all connected cameras are actively monitored during neutral, forward, and reverse travel. -
MODE 2 (Safe-to-Approach):
Designed to mute the system when the machine is in a safe, static state. When the park brake or lock-out is applied, the monitor enters Stand-by mode, and all alerts and triggers are actively suppressed. -
MODE 3 (Dynamic Detection - Dual Signal):
For machines equipped with both forward and reverse electrical signals. Actively mutes the rear camera when driving forward, and the front camera when driving in reverse. Mutes all cameras when the machine is in neutral gear. -
MODE 4 (Dynamic Detection - Single Signal):
For machines that only possess a park brake and reverse signal. It provides the same dynamic directional muting as Mode 3, but determines the forward travel state based on the release of the park brake.

MODE 1 (Default / Pass-through):
-
Wire the I/O Harness:
Connect the machine's control signals to the PXE I/O harness based on the mode you selected:- For MODE 1: FWD/MUTE-IN = Forward Signal (optional). AUX = Reverse Signal (optional).
- For MODE 2: FWD/MUTE-IN = Park Brake or Lock-out circuit. AUX = Reverse Signal (optional).
- For MODE 3: FWD/MUTE-IN = Forward Gear Signal. AUX = Reverse Gear Signal.
-
For MODE 4: FWD/MUTE-IN = Park Brake circuit. AUX = Reverse Gear Signal.

-
Reseal the Housing:
Re-insert the rubber boot firmly into the side of the PXE unit. **WARNING:** The rubber boot must be properly secured to ensure the IP66 water and dust ingress rating is maintained. -
Configure the LCD Monitor:
Power up the machine and unlock the Proxicam LCD Monitor. You must configure the software to mirror your hardware mode selection:- Navigate to the Power-up Mode menu.
- For MODE 1 and MODE 2, select your preferred default viewing layout (e.g., split or quad view).
- For MODE 3, select Stand-by.
- For MODE 4, select FRONT CH3.
- Navigate to the Triggers menu and assign the correct display priorities for the front and rear cameras.
Troubleshooting & FAQ
I have configured Mode 3 for Dynamic Detection, but the system is not muting the cameras based on the machine's direction of travel.
Verify that the physical dip switches under the rubber boot are accurately set to Mode 3. Next, ensure that both the FWD/MUTE-IN and AUX wires are receiving a stable positive voltage between 9V and 85V DC from the machine's actual gear control circuits when engaged. Finally, verify that the Proxicam LCD Monitor's Power-up Mode is strictly set to Stand-by to match the hardware logic.
Water has entered my PXE module, causing it to fail.
The PXE module achieves an IP66 rating, which protects it against high-pressure water jets and dust. However, this rating is entirely dependent on the watertight rubber boot being properly seated over the mode selector switch opening. If this boot is left out, loose, or incorrectly installed after the initial configuration, water will easily enter the housing and permanently damage the internal circuitry.
