Diablo Controls AVI-X-2 Dual Code Hands-Free AVI Transmitter
The Diablo Controls AVI-X-2 is the dual-code model in the AVI-X transmitter family. It is designed for sites that need more flexibility than a single always-on vehicle ID code. In normal use, the transmitter can send a primary code continuously and use a switch input to change how the second code is transmitted, depending on the receiver setup and site programming. In a complete installation, the AVI-X-2 is paired with a Diablo AVI receiver or code reader and a roadway receiving loop. When the vehicle enters the loop field, the receiver identifies the transmitted code and sends the programmed output to the gate, barrier, parking controller, or access-control panel. This is a good fit for commercial and controlled-entry sites that want hands-free identification but may need separate code functions for entry/exit, special authorization, fleet routing, or security logic.
Compatible With
- Diablo Controls AVI receiver and code-reader systems programmed for the transmitter's assigned code or codes.
- AVI-222 two-channel AVI receivers in compatible card-rack installations.
- Roadway loop antenna installations used for Diablo automatic vehicle identification.
- Access-control, barrier gate, parking control, fleet, emergency access, mass transit, bus, trucking, and service entrance systems where the AVI receiver output is accepted by the controller.
- Optional AVI-SD security device installations when the transmitter/security-device handshake is part of the site design.
- Related to the AVI-X-1 single-code transmitter but not the same operating setup.
- Not a direct replacement for conventional 318 MHz, 315 MHz, 390 MHz, 433 MHz, HID, AWID, Multi-Code, or MegaCode remote/credential systems.

Technician Note
Use the AVI-X-2 when the site actually needs the second code function. If the existing system only expects one continuously transmitted vehicle code, the AVI-X-1 may be the simpler match. Always verify the receiver programming and the intended switch operation before replacing or adding transmitters.
Before Ordering Checklist
- Confirm the receiver is a Diablo AVI or compatible AVI code-reader system.
- Confirm both required code values when the second code will be used.
- Verify whether the site uses AVI-X-2 switch wiring or only primary-code operation.
- Check for optional AVI-SD pairing requirements.
- Confirm the roadway loop and receiver channel are working before replacing transmitters.
Professional Advisory
AVI code programming can affect secure vehicle access. For commercial, emergency, fleet, or multi-tenant properties, have a qualified access-control technician verify the receiver settings and test the output after installation.
Important Ordering Warnings
- Do not treat the AVI-X-2 as a normal remote control transmitter.
- The second-code function must match site programming to be useful.
- A receiver that is not programmed for the transmitter codes will not authorize access.
Product Q&A
Why would I use the AVI-X-2 instead of the AVI-X-1?
Use the AVI-X-2 when the site needs a dual-code transmitter or a secondary switched code function. Use the AVI-X-1 when only one continuously transmitted code is required.
Does the AVI-X-2 include the receiver?
No. This product is the vehicle-mounted transmitter. The system also needs a compatible AVI receiver or code reader and a roadway receiving loop.
Can the AVI-X-2 open more than one entrance?
It may be used in multi-lane or multi-entry systems if each compatible receiver is programmed to accept the required transmitter code or codes.
Is this compatible with card readers or proximity readers?
It is an AVI transmitter system component, not a proximity card credential. It must be used with compatible Diablo AVI receiving equipment.
Can this be used with the AVI-SD security device?
Yes, the AVI-X family may be used with an optional AVI-SD security device when the site is designed for that transmitter/security-device pairing.
