3.4.3 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.
