Recreational Vehicle (RV)
Logic Technologies secures contract for a Flagship Recreational Vehicle (RV), DL-DM700x-RV, 7.0 inch WiFi-Enabled Touch Screen computer
Logic Technologies has won a multi-year sole-source agreement with North America’s most iconic recreational vehicle manufacturer to supply the DL-DM700x-RV, a 7.0 inch WiFi-enabled touch screen computer as the central Living Space System Controller and auxiliary repeater in the OEM’s 2026 flagship models.
Installed flush in the interior galley wall, the 7″ display consolidates climate, lighting, awning, slide-out, tank monitoring, and entertainment controls into a single intuitive interface—accessible to owners via touchscreen or smartphone, yet serviceable only by certified technicians through a patented front-install, thin-profile, anti-tamper locking system engineered… …for the RV’s extreme wall depth constraints (≤18 mm total cavity between interior panel and exterior aluminum skin).
Client Profile
Business Unit
Recreational Vehicles
Target Applications
The OEM required a 7″ touch screen controller that:
Mount
Mounts from the front (no rear access in riveted aluminum monocoque construction)
Fit
Fits within 18 mm total wall depth (12 mm interior panel + 6 mm air gap to outer skin)
Removal
Allows technician-only removal (owner-proof)
Automotive Grade
Meets automotive-grade shock, vibration, and thermal specs (SAE J1455, ISO 16750)
Wifi
Enables WiFi 6 mesh networking with the RV’s central gateway
The Challenge
RV wall construction posed unique mechanical constraints:
Constraint |
Detail |
Wall Cavity |
≤18 mm (0.71″) total — no space for rear-mount brackets or nuts |
Installation |
Front-only access; exterior skin cannot be drilled post-assembly |
Serviceability |
Technician must remove in <2 minutes; owner must not be able to |
Environmental |
-40°C to +85°C, 95% RH, 10g vibration (SAE J1211), salt-fog exposure (ASTM B117 480h) |
Security |
Prevent guest/owner tampering with system calibration or firmware |
Previous solutions used bulky rear-mount frames (>40 mm depth), required interior panel removal for service, or relied on visible screws—compromising aesthetics and warranty costs.

17.8 mm total (including bezel) |
WiFi |
Dual-band WiFi 6 (802.11ax), mesh-ready, WPA3 |
Connectivity |
CAN-FD, LIN, 1× Ethernet, USB-C (sealed), Bluetooth 5.2 |
Power |
9–32 VDC, <6W, load-dump protected (ISO 7637-2) |
Certifications |
SAE J1455, ISO 16750-3, CE, FCC, IATF 16949 (in process) |
Patented Ultra-Thin Front-Install & Anti-Tamper Lock
- Mounting Plate: 1.2 mm 301 stainless steel, bonded to interior wall with 3M VHB 5962
- Locking Mechanism:
- Four micro-cam latches (316L stainless) deploy laterally into wall cavity
- Actuated by dual-key magnetic tool (supplied only to dealer network)
- Torque threshold: >80 Nm to actuate without tool → owner-proof
- Removal Process:
- Technician places magnetic key → unlocks in 3 seconds
- Press bezel center → unit ejects 8 mm
- Pull forward → disconnect quick-release Molex Mini-Fit Jr. → <90 seconds total
- Tamper Alert: Hall-effect sensor triggers log entry via CAN if forced
WiFi Mesh Integration
- Auto-joins OEM’s RV-C/XRV mesh network
- Supports OTA firmware updates (dual-bank, signed, rollback)
- Local fallback mode if gateway offline (cached schedules)
Environmental Validation
Test |
Result |
Thermal Shock |
-40°C ↔ +85°C, 500 cycles (IEC 60068-2-14) |
Vibration |
10–2000 Hz, 7.5g RMS (SAE J1211) |
Salt Fog |
480 hours (ASTM B117) — zero corrosion |
HALT |
6-axis random vibration to failure (>22g) |
Results & Impact
Installation Time
<3 minutes per unit (vs. 45+ for rear-mount competitors)
Service Calls
0 display-related in first 6 months (vs. 3.8% industry avg)
Owner Override Attempts
0 successful (tamper log confirms 14 attempts)
WiFi Reliability
99.97% uptime in mesh (logged via cloud analytics)
Warranty Savings
Estimated $1.2M/year reduction in field service
Conclusion
The DL-DM700x-RV demonstrates Logic Technologies’ mastery of space-constrained, mission-critical HMI in mobile environments. By solving the 18 mm wall challenge with a patented micro-mechanical lock, delivering automotive-grade resilience, and enabling seamless WiFi control, Logic has become the exclusive supplier of living space controllers for the OEM’s next-generation aluminum travel trailers.
From Our Customer
““Logic’s 7-inch controller fits where nothing else could—literally. The front-install system saved us from redesigning half our interior panels, and the magnetic lock means owners admire it but can’t break it. It’s now the brain of every smart trailer we build.” ”
