11 – Twisted Pair Cabling connection
The FEM provides 4-shielded RJ-45 connectors to interface to the twisted pair links.
As each of the FEM RJ-45 4 ports supports:
full Auto-negotiation, auto-polarity and
Auto-cross,
you can simply connect any device to any port by using a standard
straight or crossed cable. If you may need to force an operation mode other than auto-
negotiation on TP port 1, this can be implemented through the front panel S9 and S10
DIP switches. Use a shielded Cable Type 5 or higher grade, up to 100m (330ft) long to
ensure proper operation at 100Mbps.
On FEM with the
Auto-cross feature
, each RJ45 port has the intelligence to sense the
type of
cable, which has been connected to it and will automatically configure itself to
either MDI or MDI-X mode of operation.
E1 Port: RJ45, 120ohm, up to ~ 2Km (Pin Layout: 5=+TX, 4= -TX, 2=+RX, 1=-RX).
