7.5 Ethernet Cable Connections
7.5.1 Ethernet Cable Specifications
The recommended cable is Category 5 or better. A Category 5 cable has four
twisted pairs of wires, which are color-coded and cannot be swapped. The
module uses only two of the four pairs.
The Ethernet port on the module is Auto-Sensing. A standard Ethernet straight-
through cable or a crossover cable can be used when connecting the module to
an Ethernet hub, a 10/100 Base-T Ethernet switch, or directly to a PC. The
module will detect the cable type and use the appropriate pins to send and
receive Ethernet signals.
Some hubs have one input that can accept either a straight-through or crossover
cable, depending on a switch position. In this case, ensure the switch position
and cable type agree.
7.5.2 Ethernet Performance
Ethernet performance on the MVI69L-MBTCP module can affect the operation of
the MBTCP application ports in the following ways.
 Accessing the web interface (refreshing the page, downloading files, and so
on) may affect performance
 High Ethernet traffic may impact performance (consider using managed
switches to reduce traffic coming to module port).
