The Adjustable Address Code 12inch Green LED Oil Price Display – No Interference is specifically engineered for multi-pump gas stations where multiple digital signs operate in close proximity. Unlike standard displays that often suffer from signal cross‑talk, ghosting, or remote control conflicts—leading to wrong prices shown on the wrong pumps—this model features a built‑in adjustable address code system. Each display can be assigned a unique digital ID, allowing you to control dozens of units independently from a single transmitter without any signal overlap. The 12‑inch large green LED digits offer exceptional daytime visibility, while the "no interference" design ensures that changing the price on Pump #3 never accidentally changes Pump #5. Whether you operate a busy highway station with 20 fueling positions or a small rural station with two separate islands, this display eliminates pricing errors, reduces staff frustration, and keeps your fuel prices accurate at all times.

• Independent Control of Multiple Displays – Each unit has its own adjustable address code (e.g., ID 01 through ID 32). One remote control can manage up to 32 displays separately, so you can update diesel, premium, and regular prices individually without affecting other signs.
• Zero Signal Interference – The address code system uses a digital filtering technology that ignores stray radio signals from nearby stations, CB radios, or other electronic devices. Your display only responds to commands sent to its specific code.
• Large 12‑inch Green Digits – Green LEDs are proven to be the most eye‑catching color for human peripheral vision, especially in bright daylight. Drivers can read prices clearly from over 200 feet away, reducing approach speed confusion at the pump island.
• Plug‑and‑Play Address Setup – Changing an address code takes less than 10 seconds. No special tools, no computer connection, and no technician required.

Q1: What exactly causes "interference" in normal oil price displays, and why doesn't yours have it?
A1: In standard displays, all units on the same frequency receive every signal. If you press "change to $3.99" on your remote, every display within range changes simultaneously. Our display solves this by requiring both the correct radio signal AND the correct matching address code. Even if interference arrives from another gas station's remote two blocks away, your display ignores it because the code doesn't match.

Q2: Can I add more displays to my station later without replacing my existing ones?
A2: Yes. All units with adjustable address codes are fully compatible with each other. Simply set the new display to an unused code (for example, ID 05 for a new biodiesel pump), and your existing remote control will manage it alongside the old ones. No system upgrade or rewiring is needed.

Q3: The green LED digits look bright at night, but are they readable under direct sunlight?
A3: Absolutely. Green LEDs typically produce 2–3 times more luminous flux per watt than red LEDs of the same power. Our 12‑inch digits use high‑intensity chips with an anti‑glare surface coating. In direct noon sunlight, the contrast remains sharp, while at night, automatic dimming (optional feature) prevents glare for drivers.

Q4: How far can the remote control work from the display without losing signal or causing interference?
A4: The effective line‑of‑sight range is approximately 150 meters (500 feet) under real station conditions—this covers even the largest truck stops. More importantly, because the address code system rejects irrelevant signals, you can stand next to Pump #1 and update Pump #15 without accidentally triggering any other display in between. For stations with thick concrete walls or metal canopies, an external antenna extension is available.
