CMeX50 is a wireless M-Bus master that can be integrated into an existing wired M-Bus solution. Up to 500 wMBUS slaves.

CMeX50 is a wireless M-Bus master that can be used by any existing wired M-Bus solution. The CMeX50 communicates with wireless M-Bus slaves via wireless modes S1, S2, T1, T2, C1, and C2 and is compatible with all widely used M-Bus slaves on the market. The CMeX50 manages up to 500 wireless M-Bus slaves, which can be individually secured using encryption keys. It also has an integrated M-Bus master for 32 wired M-Bus slaves.

## AUTOMATIC INSTALLATION

The CMeX50 can automatically install selected wireless M-Bus slaves. By enabling CMeX50 automatic installation mode, all wireless M-Bus slaves within range can be automatically detected and configured for operation. Installed wireless M-Bus slaves can subsequently be modified and configured to use encryption for secure connections.

## SIMPLE CONFIGURATION

The CMeX50 can be easily configured using the intuitive display or using standard M-Bus commands over standard 2-wire M-Bus. The display shows current operation, installed wireless slaves, M-Bus operating modes, and much more. No additional tools are needed to operate CMeX50.

## USE IN EXISTING 2-WIRE M-BUS SYSTEM

All installed wireless M-Bus slaves can be read using standard 2-wire M-Bus commands on the CMeX50 M-Bus slave port. This functionality makes CMeX50 fully compatible with any existing wired M-Bus solution. Wireless M-Bus slaves can be read individually using secondary or primary addressing mode with the standard REQ_UD2 read command.

## REMOTELY UPGRADABLE

The CMeX50 can be configured remotely using standard M-Bus commands. When new wireless M-Bus modes or M-Bus standard updates are available, the firmware can be remotely updated to meet new market demands.
