8. Wireless M-Bus Repeater AMR
The Wireless M-Bus repeater AMR (Automatic Meter Reading) from adeunis® is a ready-tu-use system allowing to repeat radio frames from
Wireless MBus transmitters.
This repeater can double the range of Wireless M-Bus transmitters AMR and thus ensure a seamless transmission of radio frames in harsh envi-
ronments or when the data concentrator is distant.
By combining several Wireless M-Bus repeaters AMR, adeunis® extends the transport of transmitted frames over several kilometers.
The repeater is available in two versions :
• Main power supply : T1 mode (S1 or R1 on demand)
• Battery power supply : T1

8.2. Implementation of Wireless M-Bus repeater AMR
8.2.1 Wireless M-Bus repeater AMR (main)
The repeater (main version) is factory configured in T1 mode (modes S1 and R1 are available on request).
For the implementation, simply connect the AC adapter, check that the operation LED power (located under the housing) is active, and the
repeater will repeat any frames RF mode concerned about 5 seconds after receipt of the initial frame.
At power up, the green LED will flash for 10/15 seconds alternately 1 second ON and 1 second OFF to indicate the correct startup of the repeat
function.
We can cascade several repeaters to extend the transmission distance.
Be careful
though not to install more than 2 repeaters in the same «zone» of radio coverage as this will cause an excess of RF frame.
Caution
: Do not attempt to use an AC adapter other than the one supplied with the product.
