E-TBT-MC04 10Base-T

Transceiver

Stand-Alone model

Attached Unit Interface (AUI) to Ethernet RJ-45 connectors

No external power requirement

The E-TBT-MC04 transceiver is a media access unit (MAU) that connects the AUI port of data terminal equipment, repeaters, or other network

devices either directly or through an AUI cable to an Ethernet 10BASE-T device. The Ethernet device is connected to the transceiver through an unshielded or shielded twisted-pair copper cable with RJ-45 connector ends.

General Description

The E-TBT-MC04, IEEE802.3 compliant Ethernet transceiver uses 10Mbps Ethernet CSMA/CD protocol to provide a connection interface to 10Base-T Ethernet unshielded twisted-pair (UTP) cables. The transceiver connects to the AUI connector of an Ethernet device via standard AUI cable.

UTP cable (RJ-45 connector)

The 10Base-T, RJ-45 out jack is used to connect a 10Base-T Ethernet device via a 2-pair UTP cable. (Use category 3, 4, or 5 UTP cable.) The length of the UTP cable can be up to 100m (328ft).

The RJ-45 connector pin configuration is shown in Figure 5. The pin assignments are show in the Table 2..

Wiring schemes for UTP cable and devices

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

Note: The device 10Base-T output jack is normally used to connect to another 10Base-T device. The vendor's 10Base-T device sometimes provides a crossover option to set the jack as an input jack for connecting to a 10Base-T Ethernet station.

Installation

Switches

The E-TBT-MC04 has a 3-position DIP switch. See Figure 6. Two of the switches provide options for enabling and disabling the SQE test and LINK test functions. Both test functions are Ethernet and 10Base-T standards.

Installation -- Continued

Connecting to a Device AUI port

The E-TBT-MC04 can connect to any Ethernet device with an AUI port. To connect to a device with an AUI port, an AUI cable or direct connection is required. See Figure 7.

The following describes the switch settings:

SW1 = SQE test: UP is enabled/DOWN is disabled

SW2 = Link test: UP is enabled/DOWN is disabled

SW3 = Duplex: UP is half/DOWN is full

SQE test

The transceiver is shipped from the factory with the SQE test switch enabled. SQE (Signal Quality Error) is the IEEE term for collisions. Depending on the Ethernet device attached to the AUI connector, set the SW “1” to the DOWN position to disable the SQE test function or to the "UP" position to enable the test.

The SQE Test (heartbeat) is a means of detecting a transceiver’s inability to detect collisions. Without this test, it would not be possible to determine if the collision detector is operating properly. The SQE test starts by generating a test signal on the collision pair from the transceiver (or its equivalent) following every transmission on the network. It does not generate any signals on the common medium.

Additionally, IEEE 802.3 specifications state that IEEE 802.3 compliant repeaters must not be attached to transceivers that generate the heartbeat.

Link test

For UTP port connection, the E-TBT-MC04 implements the link integrity test functions as specified in the IEEE 802.3 10Based-T standard. The E-TBT-MC04 will transmit link test pulses to any UTP port after that port’s transmitter is inactive for a range of 8 to 17 ms. These pulses are sent to confirm that a valid connection exists between the E-TBT-MC04 and its attached device.

Connecting to an RJ-45 device jack

IMPORTANT: If the transceiver is attached to an Ethernet repeater, a10Base-T hub, or a wiring concentrator, the SQE test function should be disabled.

To connect the transceiver to a 10Base-T device via RJ-45 jacks, see Figure 8 and do the following:

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

2.Connect one end of the UTP cable to the RJ-45 OUT jack of the transceiver.

3.Route the free end of the UTP cable to the area where the10Base-T device is located.

4.Connect the free end of the UTP cable to an RJ-45 IN jack on the 10Base-T device.
