24V/1A DC is required to power converter. Standard consumption is lower, but switched-mode power supply requires high inrush current.

1. Jumper - RS485 terminator
2. RS 485 [C-bus] connector
3. RS 232/MMI connector
4. Ethernet
5. USB Slave
6. Do not connect
7. Jumper - MMI power supply bridge between RS 232 DB9 and port 3.
8. Power supply 24V DC

1. Shielding
2. A+
3. B-
4. GND

1. GND
2. MMI power
3. TxD
4. RxD

1. -24VDC
2. +24VDC

With reverse polarity protection

1. RS 232 DB9
2. USB Host
3. HDMI Do not connect
4. Micro SD slot
5. M-Bus

1. M-Bus
2. M-Bus

With protection against overvoltage and short circuit
In the event of prolonged short-circuit situation, converter will reduce output voltage. To restore converters function it is required to break converters power supply.

  RS485 - /dev/ttyO5
  M-Bus - /dev/ttyO4
  RS232 DB9 - /dev/ttyO1
  RS232 MMI - /dev/ttyO2
