Linear DNR00104 / MGR 318MHz 12/24V MegaCode 1-Channel Wireless Gate Receiver

Linear DNR00104 / MGR 318MHz 12/24V MegaCode 1-Channel Wireless Gate Receiver

The Linear DNR00104 MGR is a one-channel 318 MHz MegaCode gate receiver used to add or restore radio control on compatible automatic gate operator systems. A one-channel receiver is typically wired to a cycle, open, or trigger input depending on the operator and the desired function. It is a practical replacement when the original receiver has failed, when a system is being converted to MegaCode transmitters, or when a remote receiver is needed outside a metal operator cabinet for better signal reception.

The key fitment issue is radio format. DNR00104 is a MegaCode receiver, not a 10 dip-switch Multi-Code receiver. It should be paired with compatible Linear MegaCode transmitters and accessories. If the customer has older 300 MHz Multi-Code remotes, the MGR is usually not the right receiver unless the remotes are also being changed.

Compatible With

Compatible Radio Family

• Linear MegaCode 318 MHz transmitters and access controls
• MegaCode remote systems requiring a one-channel receiver
• Automatic gate operators with compatible low-voltage radio input terminals

Common Applications

• Gate operator cycle/open input receiver
• Remote receiver installation where an antenna is needed outside a metal cabinet
• Replacement for failed MGR / DNR00104 receiver

Not Compatible With Without Conversion

• 300 MHz Multi-Code 10 dip-switch transmitters
• MCS109920 / 1099 style dip-switch receiver systems

Technician Note

Match receiver technology to the transmitters already in use. MegaCode and 300 MHz 10-dip Multi-Code products are different radio families and should not be mixed unless the system is being intentionally converted.

Before Ordering

• Confirm the remotes are Linear MegaCode 318 MHz transmitters.
• Confirm the operator has compatible low-voltage receiver power and trigger terminals.
• Check whether a one-channel receiver is enough or if a two-channel receiver is needed.
• Mount the receiver/antenna where the signal is not blocked by a metal enclosure.
• Program and test every transmitter after installation.

Professional Advisory

Receiver wiring is normally low voltage, but it still affects gate movement. Do not bypass safety inputs or wire a receiver in a way that defeats operator safety features.

Product Q&A

What transmitters work with DNR00104?

DNR00104 is for Linear MegaCode 318 MHz transmitter systems. Match the transmitter model to the MegaCode receiver family.

Is this the same as a 300 MHz Multi-Code receiver?

No. DNR00104/MGR is MegaCode 318 MHz. Multi-Code 300 MHz dip-switch receivers and remotes are a different system.

How many transmitters can be programmed?

The MGR is commonly listed with capacity for up to 40 transmitters.

Can this be used on a gate operator from another brand?

It may be used with many gate operators that provide compatible low-voltage receiver power and trigger terminals, but wiring must be verified by the operator manual.

Why use a remote receiver instead of the built-in receiver?

A remote receiver can improve serviceability or reception, especially when the operator cabinet blocks radio signal.
