Key Fob Pairing
A key fob can pair to a specific module or board, ensuring it only communicates with that board even if others are within range. You can also pair a single key fob to multiple boards - when in range, all paired boards will activate with a single button press.
The Key Fob Interface
Easy Key Fob Control
If your application needs wireless relay control, our Key Fob Relay Series delivers the most powerful and flexible solution on the market. These are not simple "one-function" remotes - our Key Fob boards are designed for advanced control.Configure each button to operate relays in almost any way you can imagine.
Key Fob Functions
A single button press can do far more than basic on/off control. Most users configure buttons for toggle or momentary actions:- Toggle: Press once to energize the relay, press again to turn it off.
- Momentary (Press & Release): Relay energizes while the button is held, and turns off when released.
- Relay Timer: Control for a duration of time, turns off after predetermined time
Need more? The Key Fob system supports relay grouping, timed events, flashing commands, and other advanced actions. One button can control multiple relays or energize a relay for a preset duration. We can preconfigure advanced functions as well but reccommend purchasing a Configuration Kit to make any adjustments in-house without sending the board back to us.
Key Fob Range
MS-Series Key Fobs offer a rated range of 750 ft (228 m).The MS 8-Button Key Fob with external antenna extends the range to 1,000 ft (304 m).
Range varies by environment - maximum distances are achieved outdoors with clear line-of-sight and minimal interference.
ZigMo Configuration Kit
KFX Receiver Modules are configured through Base Station Software and must be plugged into a ZIGMO Configuration Board during setup. The KFX Module is only installed in the Configuration Kit during setup - after that, it goes right back into your board. Only one ZIGMO is required no matter how many receivers you use.
The ZIGMO provides the connection between your computer and the KFX Module, allowing you to set Baud Rate, define Data Bytes, and customize the actions for each button press.
The ZIGMO is included in the KFX Integration Kit and available during checkout.
Easy Configuration
Your board includes a KFX Communications Module, enabling full key fob control.Setup is done through Base Station Software - a free, point-and-click configuration tool. Assign the exact command you want each button to send using a simple numeric command structure.
Prefer us to handle it? Just choose toggle or momentary at checkout and we'll configure it before shipping.Key Fob Configuration
