McBasic 10/100

Installation Guide

McBasic 10/100™ is a low-cost, preconfigured, IEEE 802.3 single- conversion MediaConverter that is designed to convert between 10Base-T twisted pair and 10Base-FL multi-mode or single-mode fiber or between 100Base-TX twisted pair and 100Base-SX multi-mode fiber or 100Base-FX single-mode fiber.

McBasic 10/100 is a 1U high, stand-alone unit that includes diagnostic LEDs for each port and a universal (100/240 VAC) power supply. McBasic 10/100 includes one RJ-45 connector and one pair of ST or SC connectors or one VF fiber connector.

Installing McBasic 10/100

McBasic 10/100 comes ready to install. The only adjustments that may need to be made after installation are:

lConfiguring the unit for its mode of operation.

lSetting the twisted pair port for a crossover workstation or pass-through repeater/ hub connection.

To install McBasic 10/100, first make sure that the unit is placed on a suitable flat surface, and leave some space at the back of the unit to accommodate the exhaust fan. Attach the cables between the McBasic 10/100 and each device that will be interconnected, then plug the unit into a reliable, filtered power source.

NOTE: All network cables must be connected for link LEDs to glow.

The following diagram shows the faceplate on McBasic 10/100. Regard- less of the type of fiber connector(s), the LEDs remain the same. More on the specific functions of the LEDs can be found later in this guide.

Configuring McBasic 10/100

McBasic 10/100 features an 8-position Dip switch for configuring the unit. This switch is accessed through a cut-out in the bottom of the unit.

The following table provides simplified definitions of the function of each switch. More detailed information follows.

Note: Dip switches 1, 2, 3, 7 and 8 are reserved for future use and are configured at the factory; DO NOT change these switches.

McBasic 10/100 Modes of Operation

The McBasic 10/100 MediaConverter features three possible “modes” of operation: PNP/Transparent mode, Force 10 mode and Force 100 mode. Your McBasic 10/100 should be configured for one of these modes (factory default is PNP/Transparent mode).

nPNP/Transparent mode, also known as Auto-Negotiation or plug-and-play mode, is the mode most ideally suited for the McBasic 10/100. In this mode, the converter will optimally and automatically configure for speed (10 or 100 Mbps) and duplex (Half or Full) depending on the capabilities of the end stations.

To enable PNP/Transparent mode, Dip switch 4 must be in the ON position (factory default). To disable PNP/Transparent mode, Dip switch 4 must be in the OFF position

nIn Force-10 mode, the McBasic 10/100 permits the transmission of valid 10 Mbps traffic only. In this mode, the module acts as a 10BASE-T/10BASE-FL media converter, rejecting 100 Mbps signals.

To enable Force-10 mode, set Dip switch 5 to the ON position (Dip switch 4 must be in the OFF position). To disable Force-10 mode, move Dip switch 5 to OFF (factory default).
