ACE3600 RTU-to-PC Ethernet Port Direct Connection without Hub
Note: The RJ45 connector head for this connection is standard. The numbering of the
pins is according to the standard, as shown in the figure below. Pin 1-8 are right to
left, as shown below. Therefore, any standard Ethernet crossover cable may be used.
To establish a link between an ACE3600 unit and the Ethernet port of a PC, without using a
hub, the RTU port should be defined as an IP port (10/100 BT, Static, Ethernet LAN) with an
IP address. The ports should be connected using an Ethernet crossover cable.

ACE3600 RTU Main CPU to Expansion Module Direct Connection
To establish a direct link between an ACE3600 main frame CPU and an expansion module, the
CPU's ETH1 port must be configured either as Static LAN or as I/O Expansion Comm.
Connect the CPU's ETH1 port and the expansion module's Exp. Eth1 port using an Ethernet
crossover cable, with wiring as in ACE3600 RTU-to-PC Ethernet Port Direct Connection
without Hub above.
