Overview Sleek, compact, and rich in features, Metrobility’s 10/100Mbps Delta Class AutoTwister looks as great as it operates. Designed for desktop use in any modern office, the durable AutoTwister meets strict US and international EMC regulations. This versatile device allows you to extend copper-based network distances up to 100km, connect 10Mbps devices to 100Mbps devices, and convert from copper to fiber as well as from half to full duplex.
Installation Guide Follow the simple steps outlined in this section to install and start using the Metrobility 10/100Mbps Delta Class AutoTwister. Unpack the AutoTwister and Accessories Check that the following parts are included in your box: • • • • 10/100Mbps Delta Class AutoTwister Power supply Power supply cord (North American shipments only) Four (4) rubber feet Your order has been provided with the safest possible packaging, but shipping damage occasionally does occur. Inspect your order carefully.
The unit may be oriented in any manner which allows you to make the physical connection to the power supply and leaves a minimum of six (6) inches of space for proper ventilation. Wall Mounting The AutoTwister requires no additional hardware for wall mounting. After selecting an appropriate place for installation, simply align the 1/4" keyhole opening on the bottom of the unit to a screw (6-32 maximum head size) or wall anchor.
Settings AN1 FD1 FD2 100M1 LLR2 Default DIP Switch LLCF DIP Switches The AutoTwister provides a set of six DIP switches located on the back panel. These switches allow you to select from several modes of operation. The default settings are shown below. O I O = OFF I = ON Link Loss Carry Forward Switch (LLCF) The AutoTwister incorporates Link Loss Carry Forward (LLCF) functionality as an aid in troubleshooting remote connections.
fiber optic port. A port operates at full duplex when its FD switch is ON. It operates at half duplex when its FD switch is OFF. The default is full duplex enabled. Speed Switch (100M1)* Switch 100M1 controls the speed setting for the copper port. If autonegotiation is disabled, the port speed will be the same as this switch setting, where ON is 100Mbps and OFF is 10Mbps. The default speed setting is 100Mbps. When auto-negotiation is enabled, the 100M1 switch setting is ignored.
Connect to the Network The Metrobility 10/100Mbps Delta Class AutoTwister offers the ease of plug-and-play installation. The overhang extension provides built-in protection for the two cable connectors. When making network connections with the AutoTwister, grasp the end of the cable with your index finger on the top of the connector and your thumb on the bottom, as shown in the illustration below. For easier installation, insert the copper cable to the AutoTwister before connecting the fiber.
BWDM Connection The bidirectional wavelength division multiplexed (BWDM) port provides one singlemode SC connector that supports a maximum segment length of 20km. BWDM line cards must always be used in complementary pairs. That is, a -1X model must be connected to a -1Y. The -1X cards are designed to transmit data at a wavelength of 1550nm and receive at 1310nm. Correspondingly, the -1Y cards transmit data at 1310nm and receive at 1550nm.

Apply Power Power is applied to the AutoTwister through the desktop power supply. To apply power, do the following: 1. Connect the power cord (not included with international shipments) to the power supply. 2. Connect the power supply to the AutoTwister’s DC input power jack located on the back of the unit. 3. The AutoTwister is designed with built-in cable management and protection. Turn the unit upsidedown and route the DC power cord into one of the two grooves located on each side of the unit.
User’s Guide This section contains information regarding the operating features of the Metrobility 10/100Mbps Delta Class AutoTwister. LED Indicators The Metrobility 10/100Mbps Delta Class AutoTwister provides several LEDs for the visible verification of unit status and proper functionality. The LEDs can assist in troubleshooting and with overall network diagnosis and management.
Factory Settings This section describes the preset features on the 10/100Mbps Delta Class AutoTwister. These settings cannot be changed. Full-Duplex Flow Control The AutoTwister supports flow control on each port in full duplex only. Full-duplex flow control is provided to avoid dropping packets during network congestion. If there is no buffer space available for incoming packets, the AutoTwister will issue a PAUSE frame.
Link Loss Return (LLR) The fiber optic ports of the Metrobility AutoTwister have been designed with LLR* functionality for troubleshooting a remote connection. When LLR is enabled, the fiber port’s transmitter shuts down when its receiver fails to detect a valid receive link. LLR is normally enabled on one end of the link and is typically enabled on either the unmanaged or remote device. Setting LLR on both ends of the link necessitates autorecovery. See Auto-Recovery on page 17.
Link Loss Carry Forward (LLCF) The AutoTwister incorporates LLCF* for troubleshooting remote connections. When LLCF is enabled, the ports do not transmit a link signal until they receive a link signal from the opposite port. The diagram below shows a typical network configuration with good link status using Metrobility AutoTwisters for remote connectivity. Note that LLCF is enabled as indicated in the diagram below.
Auto-Recovery A typical application of the 10/100 AutoTwister is to use it in pairs to extend a network’s reach between two distant devices. Switch/Hub w/SNMP AutoTwister AutoTwister Switch/Hub w/SNMP Fiber Cable LED lit = established link LED unlit = no link In this back-to-back setup, it may be desirable to see the entire link down if any of the connecting segments fails. This means that both copper ports must relay a no link condition to the switch/hub when any of the cables is broken.
Auto-Recovery Application Example A set of four AutoTwisters can be used to provide the redundancy necessary to ensure that data from a 100Mbps device reaches its destination in a 10Mbps device, as illustrated in the diagram below. In this example, the main link, which includes AutoTwisters A1 and A2, must be seen as a single connection. If any of the cables in the main link fails, both switch/hubs must be notified of the failure so they can activate the backup link, which includes AutoTwisters B1 and B2.
