2.1. Power supply
To power the UMX-02/0 a power supply of 24 Vdc is required.
The consumption, without cards, is 285 mA. When the various cards are inserted, the consumption will
increase depending on the model and the number of cards inserted.

01, UDCE-01, COU-01, UMX-02/0) through an RS485 bus. For this purpose, it uses the CSMA (Carrier
Sense Multiple Access) protocol.
