MC-V12 RF/RoIP Two-Way Radio — TX-Locked or TX-Enabled Configuration
The MC-V12 is a software-defined radio and network communications platform available in two configurations: Locked and Unlocked. Both configurations support receive-side radio monitoring, local dashboard viewing, recording, event history, device status, and IP-based communication features. The MC-V12 TX-Locked configuration is supplied for receive-only RF operation with IP-based communication features. Customers are responsible for using the product in accordance with applicable requirements.
The MC-V12 is designed to receive compatible radio signals and move system data through Ethernet, Wi-Fi, or other configured IP network connections. IP network functions may include dashboard access, remote monitoring, recording transfer, alerts, Push-to-Talk voice over IP, Push-to-Video over IP, messaging, and system administration.
Available Configurations
MC-V12 Locked Configuration
The Locked configuration is supplied with radio-frequency transmit functions disabled.
In this configuration, the MC-V12 can receive compatible radio signals, display activity, record audio, show device status, and send data over Ethernet, Wi-Fi, or internet-connected IP networks.
PTT and PTV functions remain available in the Locked configuration, but they operate through ROIP and IP networking only. They do not transmit through DMR, RF push-to-talk, repeater channels, or monitored radio channels.
Locked configuration features include:
Receive-only RF operation
No DMR RF transmission
No RF push-to-talk transmission
No RF repeater operation
ROIP Push-to-Talk over IP
Push-to-Video over IP
Messaging and file transfer over IP
Live audio monitoring
Recording and playback
Event timeline
Local operations grid
Receiver status display
Ethernet and Wi-Fi network connectivity
Web-based dashboard access
MC-V12 Unlocked Configuration
The Unlocked configuration enables supported outbound RF communication features when properly configured and used in accordance with applicable laws, licensing requirements, frequency authorizations, and operating rules.
In this configuration, the MC-V12 may support RF transmit functions in addition to the IP-based communication functions available in the Locked version. Available transmit modes, frequency ranges, power levels, antennas, and operating features depend on the purchased configuration and approved setup.
Unlocked configuration features may include:
Supported RF transmit operation
RF push-to-talk where authorized
RF data communication where authorized
Receive-side radio monitoring
Recording and playback
Local operations grid
Direct device-to-device RF communication
Peer-to-peer voice, video, text, image, and data exchange
Mesh networking between MC-V12 units
Repeater-assisted mesh operation
Base-station coordination
Multi-node routing
Field-deployable local network operation
Directional antenna integration
Configurable modulation and bandwidth settings
Adaptive RF configuration based on operating conditions
AES 256 encrypted communication paths where configured
User-managed key provisioning where configured
RoIP bridge operation between RF and IP-connected users
Important RF and Network Clarification
“Locked” and “Unlocked” refer to the MC-V12 radio-frequency operating configuration.
The Locked configuration does not transmit over DMR or monitored RF channels. However, it can still send and receive ordinary digital data over Ethernet, Wi-Fi, private networks, VPN connections, or internet service.
The Unlocked configuration may include RF transmit capability, but only for supported and authorized operating conditions. Users are responsible for complying with all applicable radio, privacy, recording, and network-use requirements.
