ID: man-multicon Multicon Manual Rev. L
Note: Note that if the standard RS-232 cable specification (DCE) is fol-
lowed:
• a cable with Male+Male or Female+Female connectors at the cable ends is used for Rx/Tx
crossed connection, and
• a cable with Male+Female connectors at the cable ends is used for a straight through
connection.
12.13.1 Maximum Cable Length (RS-232)
IEEE has specified the maximum cable length for an RS-232 connection to 15m. Longer distances
can be installed depending on the environmental conditions of the installation site.
Note: It is the responsibility of the installation personnel to secure a
proper installation of the RS-232 connection.
12.14 Ethernet Connectivity
The connections follow the standard set by the IEEE 802.3 100BaseTX specification. The cables
that are to be applied should be CAT-5 / CAT-5E standard, or better.
Note: It is the responsibility of the installation personnel to secure a
proper installation of the Ethernet connection.
12.14.1 Ethernet connections on Mk4
The backplane on Multicon hardware revision 4 has two ethernet interfaces.
• GBE1: Main connection to control network
• GBE2: Debug port (not used)
12.15 External RS422 Flashlink Connectivity
It is possible to connect Multicon in an N-BOX housing to Flashlink Compact units using an RJ45
connector on the back plane of the Multicon card. This is also referred to COM3 in the figure
above and provides the ability to connect to the RS422 Flashlink bus externally instead of internally
within a frame.
