The Connex Mini operates on the 5GHz band with dynamic frequency selection and does not allow manual channel selection.
The system showed reliable signal penetration through cinderblock walls at several hundred feet distance with fast re-linking and no visible image delay.
The Connex Mini uses HDMI connectors which limit its use in SDI-based workflows without additional converters.
The transmitter features delicate micro HDMI and VST power connectors that require careful cable management to prevent damage.
An SDI solution for the Connex Mini was developed using a Blackmagic Micro SDI converter with D-tap power delivery.
The Blackmagic Micro SDI converter does not support 23.98/24 PsF video formats.
The Connex Mini transmitter does not include a cooling fan, while the full-size Connex operates a fan continuously that produces approximately 32-36 dBA at 2 feet.
CMR offers accessory packages including rod antennas for the receiver, battery cages with mounting points for lithium batteries, and various cables including P-tap.
Range specifications indicate 3300 feet for the full-size Connex and 1600 feet for the Connex Mini, though practical performance at typical set distances under 100 feet proved robust.
Multiple Connex Mini units can be deployed simultaneously in the same environment.

The system is HDMI-based, requiring SDI-to-HDMI conversion for SDI camera workflows.
The review describes use cases limited to small handheld monitors and stationary displays rather than direct on-camera mounting.
Testing covered distances of several hundred feet in stage environments; performance at maximum rated range was not evaluated.
The Blackmagic Micro converter solution introduces additional bulk and power requirements compared to direct HDMI connection.
Attempts to reduce cooling fan noise on the full-size Connex through baffles achieved only 2-3 dBA reduction.
