Embedded Serial Port Cables
Embedded serial port cables for communication are listed here. All embedded serial
port cables must be 3 meters in length, or shorter.
Embedded Ethernet Support
For Micro850 controllers, a 10/100 Base-T Port (with embedded green and
yellow LED indicators) is available for connection to an Ethernet network
through any standard RJ-45 Ethernet cable. The LED indicators serve as
indicators for transmit and receive status.
Micro850 controllers support Ethernet crossover cables (2711P-CBL-EX04).
Ethernet Status Indication
Micro850 controllers also support two LEDs for EtherNet/IP to indicate the
following:
• Module status
• Network status
for descriptions of Module and Network status
indicators.
