Installation

Attaching to an Ethernet device via an AUI cable

The Ethernet device can be a network interface controller, wiring concentrator, or repeater that provides an AUI port. For attaching to such device, an AUI cable of appropriate length is required. The following figure illustrates the connection of the transceiver and an Ethernet device via an AUI cable.

Important:

If the transceiver is attached to an Ethernet repeater, a 10Base-T hub, or a wiring concentrator, the SQE test function should be disabled.

Connecting to a 10Base-T Ethernet Hub

To connect the transceiver to a 10Base-T hub, follow the steps:

1.Select an appropriate length UTP cable for the connection.

2.Connect one end of the UTP cable to the RJ45 jack of the transceiver.

3.Route the free end of the UTP cable to area where the 10Base-T hub is located.

4.Connect the free end of the UTP cable to an IN jack on the 10Base-T hub.

Interpreting LED Indicators

There are six diagnostic LED indicators provided on the transceiver to indicate the operation status as below:

LED	Operation status	State	Interpretation
Power	Power status	On	Transceiver is on.
		Off	Transceiver is off.
Link	UTP link status	On	The UTP link is ok or link
			test function is disabled.
		Off	No UTP link or UTP link is
			faulty.
		Blink	UTP link is faulty.
TRX	Transmission status	Blink	Transmission is in operation.
		Off	No transmission.
		On	Normal, if large transmission is
			in operation.
			Problem, if no transmission.
RCV	Receiving status	Blink	Receiving data packet
		Off	No packet is being received.
		On	Normal, if heavy traffic load.
			Normal, if no UTP link.
			Problem, if no network traffic.
COL	Collision status	Off	No collision occurs.
		Blink	There is presence of collisions.
POL	Polarity reversal	Off	There is no polarity reversal
			problem detected on the UTP
			cable.
		On	Polarity reversal problem
			exists on the receiving pair
			of the UTP cable.

Wiring the UTP Cable

How to install the UTP cable is determined by the characteristics of the 10Base-T UTP port of the device connected at the other end of the cable. The following figure shows some examples:

Wiring for the UTP cable
	Pin	Pin
	1 ------------	1
Transceiver	2 ------------	2	10Base-T hub's
	3 ------------	3	IN jack
	6 ------------	6
	Pin	Pin
	1 ------------	3
Transceiver	2 ------------	6	10Base-T hub's
	3 ------------	1	OUT jack
	6 ------------	2
	Pin	Pin

	3 ------------	1
	6 ------------	2

Note: The OUT jack of a 10Base-T hub is normally used for connection to another 10Base-T hub. The vendor's 10Base-T hub, sometimes, provides a crossover option to set the jack as an IN jack for connection to a 10Base-T Ethernet station.
