3.5.2 Connecting the peripheral components to the AMC2
The AMC2 possesses 23 connectors of the pluggable screw terminal type. Wires can be
fastened with holding screws to the terminals, and these terminals can be plugged and
unplugged at the AMC2.
We will use nearly all the available connections, as shown in Section Figure 3.5 The AMC2
connections used in the 4-room surgery example., page 15. The numbering scheme S1-S23 is
taken from the AMC2-4R4 installation guide.
We will connect 2 readers (Main entrance and Laboratory) in a bus topology to connection S2,
and 2 readers (Storeroom and Office) to connection S7. Note: S2 and S7 are both connectors
to the same RS-485 bus, and this bus may only have a total of 8 readers. The two reader
connectors on the upper edge of the AMC2 4R4 (S14 and S19) are not used.
4 AMC On the underside of the AMC’s circuit board, set the
relay output jumpers for the relay outputs to “wet
mode” i.e. the AMC2 should provide a voltage to our
door openers.
In the illustration opposite...
jumper setting 1 shows “dry” (voltage free) mode, and
setting 2 shows “wet” (voltage provided) mode.

5 AMC Ensure that the DIL switch number one is set ON and
the rest are off, to identify this AMC to the software as
device number one via the ethernet connection.

7 AMC Short circuit the tamper contact at S13, see Figure 3.5.
This connection exists to provide protection against
tampering with the AMC device. For our simple
example we do not require it, and rely instead upon
the security of the office itself.

CAUTION!
Note: To use door openers or other devices with their own external power supplies you must
ensure the relay output jumpers are set to the factory-default “dry mode” position, i.e.
providing no voltage to the relay outputs.
