Metr Introduction obility “twister” media converters represent the hottest technology available for extending Ethernet networks. Since Metrobility first developed “twister” media conversion, it has become a standard for providing cost-effective means of integrating mixed media environments. As LANs grow and evolve, this technology provides the ideal solution for building effective migration strategies. Designed to meet IEEE 802.3 compliance, these media converters are compatible with Ethernet devices from other leading network technology providers. This increases the flexibility of your network by ensuring reliable data transmission in multi-vendor as well as mixed media environments. The information in this guide will help you to install and start using your “twister” 2111 media converter. Overview The Metrobility “twister” 2111 10 Mbps media converter provides seamless integration of 10BASE-T Category 3, 4, and 5 twisted-pair segments with either multimode 10BASE-FL fiber optic segments or thinnet coax in Ethernet environ- ments. To optimize your Ethernet network, the 2111 media converter provides seamless operation in half- or full-duplex modes. Full signal restoration—with a low bit delay—ensures accurate data transmission to and from LANs within an organization. All signal activity is completely converted ensuring accurate communication and collision detection in connected segments and allowing maximum media length to be achieved on either side of the device. The “twister” 2111 provides the following key features: • MDI-II/MDI-X switch on the twisted-pair port to eliminate the need for crossover cables. • Transparency Mode that allows auto-negotiation by end points through the media converter. (2111-13-B and 2111-15-B only.) • Auto polarity on the twisted-pair port. • Half- and full-duplex support. • Low bit delay to ensure accurate data flow across the network. • Transparency to data frame sizes. • Full compliance with applicable sections of IEEE 802.3. 4 Installation Guide Follow the simple steps outlined in this section of the guide to install and start using your Metrobility “twister” media converter. Unpack the “twister” and Accessories Check that the following components have been included with your order: • “twister” 2111 media converter 1 • Power supply • Power cord • Four (4) rubber feet Your order has been provided with the safest possible packaging, but shipping damage does occasionally occur. Inspect your order carefully. If you discover any shipping damage, notify the carrier and follow their instructions for damage and claims. Save the original shipping carton if return or storage of the unit is necessary. Attach the Rubber Feet The “twister” 2111 is shipped with four rubber feet. To install the feet, turn the “twister” upside-down. Peel the self-adhesive rubber feet from the paper 2 strip and attach one foot to each corner on the bottom of the “twister” 2111. Installing the feet provides an air gap which helps to cool the unit, adds stability, and prevents marring and scratching of the desktop surface. Choose an Appropriate Location The “twister” 2111 media converter is intended for use in an office or industrial environment. The unit must be located within six (6) feet of the 3 AC power source being used and placed as far away as possible from electrical noise generating equipment such as copiers, electrostatic printers, and other motorized equipment. If exposed twisted-pair wiring is used nearby, the wiring should be routed as far away as possible from power cords and data cables to minimize interference. The units may be oriented in any manner that permits you to make physical connection to the power supply and leaves a minimum of six (6) inches of space for proper ventilation. TUV Compliance Note: For pluggable equipment, the socket outlet must be installed near the equipment and be easily accessible. Bei Geräten mit Steckanschluß muß die Steckdose nahe dem Gerät angebracht und leicht zugänglich sein. “twister” 2111 Media Converter 5 Set the Switches Termination Switch (2111-12-01 only) 4 The “twister” 2111-12-01 has a termination switch located on the front panel. This switch, labeled TERM, is used to set either internal or external termination on the BNC port. External termination is enabled when the switch is in the OFF position (default). Use this setting if the “twister” will be used in a daisy-chain configuration, or if you must use a BNC T-connector and terminator for proper external termination. Internal 50Ω termination is enabled when the switch is in the ON position. To change the setting, use a pointed object to slide the switch. When internal termination is enabled, the unit’s BNC port can be connected directly to another device, without the use of an external BNC terminator. ™ “twister” 2111 10BASE-2 10BASE-T COL PWR TERM ACT LINK ON OFF Termination Switch (default is OFF) 6 Installation Guide Transparency Switch (2111-13-B and 2111-15-B only) The “twister” 2111-13-B and 2111-15-B have a set of DIP switches located on the back panel. Only the transparency switch, labeled TSP, is configurable. All other DIP switches are nonfunctional. When TSP is ON (default), the “twister” becomes completely transparent to the end devices connected to its two ports. This allows the devices to perform auto-negotiation directly with each other. For most applications, we recommend this mode of operation. When TSP is disabled (OFF), you must manually configure the speed and duplex on both end devices to the same setting. Refer to Transparency Mode for more information about this feature. DIP ON PWR switches OFF DC INPUT/5VDC ON default OFF settings “twister” 2111 Media Converter 7 TSP TSP MDI-II to MDI-X Switch All “twister” media converters with twisted-pair ports have an MDI-II to MDI-X switch that eliminates the need for crossover cables. The switch allows simple setup in either straight through or crossover configurations. It is located on the bottom of the unit directly below the RJ-45 connector, or on the front panel between the two ports. Refer to the illustrations below. ™ ™ “twister” 2111 ™ “twister” 2111 “twister” 2111 10BASE-FL 10BASE-2 10BASE-T 10BASE-T TX RX COL PWR PWR TX SM TERM RX AT AT LK PWR ON OFF ACT LINK LK AT LK AT LK 10BASE-FL 10BASE-T MDI-II / MDI-X Switch MDI-II / MDI-X Switch (default is MDI-II) (default is MDI-II) When setting the MDI-II to MDI-X switch, observe the positioning of the following symbols: • The parallel symbol (II ) indicates a straight through or parallel connection. (default) • The cross symbol (X) indicates a crossover connection. These symbols are clearly marked on the unit. Using a pointed object, simply slide the switch in the direction of the appropriate symbol, or press the switch to the desired setting. Use the following table as a guide: A device that is wired straight through, needs one crossover connection: If the cable is the MDI-II to MDI-X switch setting should be straight through X crossover II A device that is wired crossover, needs a parallel connection: If the cable is the MDI-II to MDI-X switch setting should be straight through II crossover X 8 Installation Guide II x Connect to the Network The Metrobility “twister” 2111 media converter offers the ease of plug-and- play installation.

This power module is equipped with a S760 hollow- 6 type plug for insertion into the DC jack located on the back of the “twister” unit and standard IEC 320-type AC power receptacle. When making power connections, it is recommended that the DC power cord be connected to the DC input jack located on the back of the “twister” media converter before making the AC connection to the outlet. ON PWR OFF DC INPUT/5VDC Upon receiving power, the “twister” media converter goes into normal operation mode and automatically provides the appropriate signal translation between the connected network segments. Be sure to verify correct segment connectivity via the link (LK) LEDs on the front of the unit. If an additional extension cord is used to connect the power module to the power source, the following guidelines must be followed. While one end of the AC power cord can be fitted with whatever plug is standard for the country of operation, the end that connects to the “twister” power supply module must have a female plug that fits this type of AC receptacle. “twister” 2111 Media Converter 13 TSP • AC 115V (North American): use a UL-listed and CSA-certified cord set consisting of a minimum No. 18 AWG, type SVT or SJT three- conductor cord (15 feet maximum length) and a parallel blade grounding-type attachment plug rated 15A, 125V. • AC 230V (USA): use a UL-listed cord set consisting of a minimum No. 18 AWG, type SVT three-conductor cord (15 feet maximum length) and a tandem blade grounding-type attachment plug rated 15A, 250V. • 240V (outside USA): use a cord set consisting of a minimum No. 18 AWG cord and grounding-type attachment plug rated 15A, 250V.

System LEDs The Metrobility “twister” 2111 media converter provides LEDs for the visible verification of unit status and proper functionality as well as aiding in troubleshoot- ing and overall network diagnosis and management. LEDs indicate the following: • PWR (power): the unit is receiving power and functioning normally. • LK: (link): satisfactory link status on the respective port. • AT (activity): the respective port is receiving data. * • COL (collision): detection of a collision condition and subsequent JAM packets generated on both segments. Once power is applied to the unit, you can verify correct connectivity via the LK LED(s). * Applies to the “twister” 2111-12-01 only. “twister” 2111 Media Converter 15 Transparency Mode (2111-13-B and 2111-15-B only) By default, the “twister” 2111-13-B and 2111-15-B are configured with the Transparency Mode enabled (ON). In this mode, the “twister” is completely transparent to devices connected to its ports. To the end devices, it appears that they have a direct connection to each other and can auto-negotiate their duplex mode. Both end devices can also see any link loss conditions simultaneously. For most applications, we recommend this mode of operation. The following diagram shows a typical network configuration using two “twister” 2111-xx-B media converters for remote connectivity. Because Transparency (TSP) is enabled, the end devices can negotiate whether to use half or full duplex.
