TJ1-MC__ Connections

The TJ1-MC__ comes with these connectors:
• One Ethernet connector, to connect to a PC or Ethernet
network (D)
• One serial connector (G).
• One 28-pin I/O connector (H).
The parts for the serial connector and the 28-pin connector are
supplied.
Ethernet connector
The Ethernet connector is used to connect the TJ1-MC__ to a PC
or Ethernet network. The Ethernet connector is the only connection
that can be used to program the system. Use either a crossover or
a Ethernet patch cable for this connection. If you connect the PC
directly to the TJ1-MC__, and not via a hub or any other network
device, the PC must have a fixed IP address.
The TJ1-MC__ automatically detects when a cable is connected to
the Ethernet connector.
BASIC installation precautions
Make sure that the Ethernet system is to the IEEE Std 802.3
standard.
Do not install the Ethernet system near a source of noise.
Environmental precautions
UTP cables are not shielded. In environments that are subject to
noise use a system with shielded twisted-pair (STP) cable and
hubs suitable for an FA environment.
Install twisted-pair cables away from high-voltage lines and devices
that generate noise.
Install twisted-pair cables in locations that are free of high humidity
and excessive dust and contaminates.
