Page 4: Introduction
Introduction Metrobility “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. -
Page 5: Installation Guide
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 •... -
Page 6: Step 4: Set The Switches
Set the Switches Termination Switch (2111-12-01 only) 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). -
Page 7: Transparency Switch
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. -
Page 8: Mdi-Ii To Mdi-X Switch
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. -
Page 9: Step 5: Connect To The Network
Connect to the Network The Metrobility “twister” 2111 media converter offers the ease of plug-and- play installation. Refer to the appropriate section below for guidelines regarding specific network connections. Twisted-pair Interface (all models) The “twister” 2111 provides one shielded RJ-45 connector for Category 3, 4, or 5 twisted-pair segments and supports a maximum link length of up to 100 meters. -
Page 10: Fiber Optic Interface
Fiber Optic Interface The following “twister” models support 10BASE-FL segments via ST or SC connectors. • The 2111-13-B provides one set of FL multimode SC connectors, which support a maximum segment length of up to 2 km for remote links. •... -
Page 11: Bnc Interface
BNC Interface (2111-12-01) The “twister” 2111-12-01 attaches to thinnet coaxial cable via a standard BNC connector and supports a maximum segment length of 185 meters. IMPORTANT: The coaxial cable of a LAN must be properly terminated at the end of each segment regardless of the device used at the end of each cable. - Page 12 When the internal 50Ω termination switch is enabled (ON), the “twister” can be connected directly to a workstation or other device. When the termination switch on the “twister” is disabled (OFF), you must attach a BNC terminator to the T-connector which connects to the unit. The example below illustrates how to connect the “twister”...

Page 13: Step 6: Apply Power
Apply Power Power is provided to the “twister” unit from the 90-250V universal desktop power supply module. This power module is equipped with a S760 hollow- type plug for insertion into the DC jack located on the back of the “twister” unit and standard IEC 320-type AC power receptacle. - Page 14 • 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. •...

Page 16: Transparency Mode
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. - Page 17 Switch/Hub Remote Management 2111-xx-B 2111-xx-B Station w/SNMP Device twister twister AN is OFF TSP is ON TSP is ON AN is OFF Link loss is forwarded LED lit = established link LED unlit = no link When the Transparency Mode is disabled (OFF), you must manually configure the speed and duplex on both end devices to the same setting.
