Figure 4.18: Location of the RS-485 interfaces for external devices
The interfaces 1 and 2 build a bus (bus 1) for its own like the
interfaces 3 and 4 (bus 2).
All eight possible readers can connect to each of the busses in
any combination. However the addresses of the readers must be
unique on an AMC2.
Depending on the input voltage of the AMC2-4R4 either 12 V or
24 V is available for the readers.
A complete connection diagram of the RS-485 interface is
shown in chapter Connecting Diagrams, page 58.
Notice!
Please check which voltage the readers require. If this does not
correspond to the input voltage or if the power consumption is
higher than 1.5 A then the readers will require external power
supply.
