Diablo Controls AVI-X-1 Single Code Hands-Free AVI Transmitter
The Diablo Controls AVI-X-1 is the single-code version of the AVI-X automatic vehicle identification transmitter. It is normally mounted on or in an authorized vehicle and wired to the vehicle power source so the transmitter sends its assigned code whenever power is present. In a complete AVI system, a loop installed in the driveway or lane acts as the receiving antenna for a Diablo AVI receiver or code reader. The receiver then decides whether the transmitted code is valid for that lane, gate, barrier, door, or access-control input. This type of product is often used where the site wants hands-free vehicle access without issuing conventional handheld remotes. Typical examples include gated communities, fleet yards, parking facilities, emergency vehicle entrances, bus or transit lanes, trucking facilities, and controlled service roads. Correct fitment depends on the receiver being a compatible Diablo AVI system using the supported code format, not simply on the gate operator brand.
Compatible With
- Diablo Controls AVI automatic vehicle identification systems using compatible receiver/code-reader equipment.
- AVI-222 two-channel card-rack receivers when the receiver is programmed for the transmitter code.
- Diablo AVI receiving loops installed in the roadway for hands-free code pickup.
- Select Diablo AVI code readers and AVI receiver installations using the standard Motorola-style code format.
- Gate operator, barrier gate, parking control, transit, emergency access, trucking, fleet, and access-control systems where the AVI receiver provides the final dry contact or solid-state output to the controller.
- Optional AVI-SD security device installations when the site is using the paired transmitter/security-device setup.
- Not for LiftMaster, Linear MegaCode, Multi-Code, Genie, DoorKing MicroPLUS, HID, AWID, or standard RF remote receiver systems unless a compatible Diablo AVI receiver is also installed.

Technician Note
The AVI-X-1 is not selected by gate operator model alone. Match it to the receiver, assigned code, loop antenna layout, and the site's AVI programming records. If the original system uses a different AVI receiver family or an older code list, the transmitter may require programming or may not be accepted by the receiver.
Before Ordering Checklist
- Confirm the existing site uses a Diablo Controls AVI receiver or compatible AVI code reader.
- Confirm the required transmitter code before ordering or programming.
- Verify whether the site needs the single-code AVI-X-1 or the dual-code AVI-X-2.
- Check whether the installation uses an AVI-SD security device.
- Confirm vehicle power wiring, mounting location, and receiver loop placement.
Professional Advisory
Vehicle power wiring, access-control programming, and receiver validation should be handled by a qualified gate or access-control technician when the site controls emergency, commercial, or tenant access. Do not bypass access-control or safety devices to force a vehicle through the gate.
Important Ordering Warnings
- AVI-X transmitters are not interchangeable with normal handheld gate remotes.
- A matching physical transmitter does not guarantee access unless the receiver accepts the programmed code.
- Do not order AVI-X-1 when the site requires a manual secondary code function from the AVI-X-2.
Product Q&A
What is the difference between the AVI-X-1 and AVI-X-2?
The AVI-X-1 continuously transmits one assigned code when power is applied. The AVI-X-2 is the related dual-code version and can provide a second code function depending on how the switch input is used.
Will this work with any gate opener?
It works through a compatible Diablo AVI receiver or code reader. The gate operator only sees the output from that receiver, so the receiver format and code programming matter more than the operator brand.
Does this replace a handheld remote?
No. This is a vehicle-mounted AVI transmitter for hands-free vehicle identification, not a standard visor remote or keychain transmitter.
Is a loop required for this transmitter?
A Diablo AVI receiving loop or compatible antenna loop is normally part of the system because the receiver reads the transmitter through the loop installed in the lane.
Can this be used for emergency vehicle access?
Yes, it is commonly used in emergency, fleet, transit, and controlled-entry applications when the complete AVI system is properly installed and programmed.
