4) RS232 control port:
The RS232 control port is implemented using a DB9 connector. Any communication
between the APC100MK2 and external control hardware equipped with an RS232 control
port can be made in this way. The pinout and communication protocol settings are
described in chapter 1 of this manual.
5) Ethernet connection:
The APC100MK2 is equipped with an Ethernet network connection implemented using
an RJ45 connector. The green and orange LED’s will indicate whether the network is
connected and active. Using this port, the APC100MK2 can be connected in any LAN
network.

‘RS485 + AUDIO’ RJ45 connector:
The rear panel of the APC100MK2 contains only one data bus connection. This data
bus connection has identical possibilities and specifications as the data bus connection
implemented on the front panel of the APC100MK2. When a connection between the
APC100MK2 and a peripheral interface or matrix system is made, the selection between
both connections can be freely chosen.
The advantage of the second implemented data bus makes the APC100MK2 applicable
to a connection between a peripheral device (wall panel, paging microphone, ... ) and a
matrix system. In this typical application one data bus connection can be used as input
while the second connection can be used as output.
