Connection between SAR 110 Router to Hub. Crossover?

Should I use a straight through ehternet cable or do I Need to get a crossover cable?

I am correct in thinking that connecting a straightthrough calbe to the uplink port on the hub has the same effect as connecting a straight through calbe to a normal port?

Yes to your last question, so you have answered your first yourself!! :lol:
If in doubt keep an eye on the LED's on the switch/ hub that will monitor the state of the connection (Cable connected, data movement etc)

You can tell the differance by placing the two connector jacks side my side.

EG.

Cable towards you body, pins facing up and away from you, with both connectors.

A straight through cable, will match, colour for colours as you look from pin 1 to 8 (left to right).

A cross-over cable doesn't match.

With a networkcard and hub model, you connect the two sending wires and the PC, to the 2 receiving wires in the hub.

If you do this PC to PC, then with a straight through wire, you end up with sending wires to sending wires.

This is what a cross-over is for. To compensate when linking two devices directly, and not through a hub/switch.

Here is how to tell if they are wired correctly, for both cross-over and straight.

Straight.
Using the guide above to holding the jacks the following should be true. Read the plugs from left to right (pin 1 to Cool

The colours should follow this pattern.

Left Pin1 = Right Pin 1
Left Pin2 = Right Pin 2
Left Pin3 = Right Pin 3
Left Pin4 = Right Pin 4
Left Pin5 = Right Pin 5
Left Pin6 = Right Pin 6
Left Pin7 = Right Pin 7
Left Pin8 = Right Pin 8

Cross-over

Do the same above, and the colours should follow this pattern.

Left Pin1 = Right Pin 3
Left Pin2 = Right Pin 6
Left Pin3 = Right Pin 1
Left Pin4 = Right Pin 4
Left Pin5 = Right Pin 5
Left Pin6 = Right Pin 2
Left Pin7 = Right Pin 7
Left Pin8 = Right Pin 8

If any other pattern is matched, then you have a faulty cable.
