[. . . ] The Transceiver Module can transmit and receive Ethernet 10 Mbit/sec traffic over Shielded or Unshielded Twisted Pair cable. The Transceiver Module features crossover (MDI/MDIX) switching, SQE Test selection and link monitoring using the Link LED (Light Emitting Diode). The Transceiver Module is used to provide connectivity to twisted pair cable on the following LinkBuilder products: · ECS modules (3C12076, and 3C12050/1) · MSH modules (3C18110, 3C18120, 3C18124, 3C18146 and 3C18600 ) · FMS Stackable Hubs (3C16250, 3C16265, 3C16271 and 3C16371) · FMS II Stackable Hubs (3C16665, 3C16670, 3C16671 and 3C16672) LinkBuilder TP/12 (3C16170) and LinkBuilder TP/8i (3C16181) hubs Repeaters (3C16170, 3C16200, 3C16210 and 3C16505). This product has the benefit of a "lifetime warranty", details of which are given on page 4 of this manual. 2 Setting up the Module MDI/MDIX The PL2 component switches the TP port between MDI and MDIX. MDI is the default setting and allows the Transceiver Module to be connected by normal twisted pair cable to an MDIX port on another hub to form an inter-repeater link. If MDIX is selected the Transceiver Module can be connected to a workstation or any other Data Terminal Equipment. It can also be connected to another hub which is already set to MDI to form an inter-repeater link. See Figure 1 to locate the MDI/MDIX jumper and then Figure 2 to ensure you have the correct selection. Page 4 Page 1 SQE Test The PL1 component allows you to enable or disable the SQE Test. The SQE Test is used by 802. 3 transceivers to confirm that the transceiver is functioning correctly. The function must be disabled for operation when installed in a Repeater. The function should be enabled for operation when connected to a LinkBuilder ECS Local Bridge Module 3C12050/1. See Figure 1 to locate the SQE Test jumper and then Figure 3 to ensure you have the correct selection. 3 Installation Only qualified personnel should install this device. A 16-pin header and a 16-way edge connector are mounted on the Transceiver Module for connection to a Module, Stackable Hub or Repeater. A Twisted Pair cable can be connected to the RJ45 connector on the front of the Transceiver Module. Remove the blanking plate from the unit in which you are going to install the Transceiver Module. Keep the blanking plate in a safe place so that it can be replaced if the Transceiver Module is removed. ! Installing in a Stackable Hub or Repeater For FMS Stackables and Repeaters, hold the mounting panel with the pin header side of the board down. For FMS II Stackables, hold the mounting panel with the pin header side of the board up. Insert the edge connector end of the Transceiver Module into the rear of the mother device. Slide the Transceiver Module in carefully to engage in the slot and push it fully home. Fix the mounting panel of the Transceiver Module to the back panel using the two screws from the blanking plate.

Radio Frequency Interference Statement This equipment has been tested with a class A computing device and has been found to comply with part 15 of FCC Rules. Operation in a residential area may cause unacceptable interference to radio and TV receptions requiring the operator to take whatever steps are necessary to correct the interference. This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus as set out in the interference-causing equipment standard entitled "Digital Apparatus", ICES-003 of the Department of Communications. Cet appareil numérique respecte les limites de bruits radioélectriques applicables aux appareils numériques de Classe A prescrites dans la norme sur le matériel brouilleur : "Appareils Numériques", NMB-003 édictée par le ministre des Communications. If the Link LED does not light when the Transceiver Module is installed the cause may be one of the following: Both ends of the link are configured as MDI - change one to MDIX. [. . . ]
