Now, migration or expansion of existing networks can be achieved with minimum cost and complexity. The Converter is completely transparent to the network so the network performs exactly the way it did before only now it can migrate both UTP and coaxial mediums. Expands the Size of an Existing Network Provides UTP/coaxial connectivity to Ethernet segments, allowing for even further networking expansion between extended nodes. Allows for the quick and easy addition of coaxial segments to existing 10Base-T networks. Enhances Networking Distances Connecting the Converter to UTP segments can further extend distances of up to 185 meters for a total segment length of 285 meters. The Converter can be connected to an additional fiber converter for even longer extensions. -5- 10Base-T to 10Base-2 Converter Cabling Flexibility This unit allows network managers to put UTP cabling anywhere within a network without retrofitting the arrangement of the Ethernet network. Its sleek design makes it easy to be installed in compact spaces or on wall mount locations. Several converters can be simultaneously installed by using a 19” Rack-mount Chassis.

When selecting a site, we recommend considering the following rules: • Install the Converter in a fairly cool and dry place. See Technical Specifications for the acceptable temperature and humidity operating ranges. • Install the Converter in a location free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight. • Leave at least 10cm of space at the front and rear of the unit for ventilation. • Affix the provided rubber pads to the bottom of the Converter for grip, and to protect the case from scratching. -8- 10Base-T to 10Base-2 Converter MDI/MDI-X Connection The MDI/MDI-X push button alleviates the worry of cable type configuration when connecting the converter with another 10Base-T device. Simply refer to the table below for the correct switch selection: Connection to Data Terminal Device Cable Configuration Selection Hub or Switch Straight Through Select MDI Hub or Switch Crossover Select MDI-X DTE (NIC) Straight Through Select MDI Crossover Selection Table MDI-X MDI 10Base-T Location of Crossover Switch -9- 10Base-T to 10Base-2 Converter Installing Your Converter 10Base-T Connection 1. Make sure that the length for straight through twisted pair cable between 10Base-T device (hub or switch) and the Converter is no greater than 100 meters. 2. Connect one end of twisted pair cable to RJ-45 jack on the Converter and the other to the RJ-45 jack on the 10Base-T device. 3. Check the corresponding port LED on the Converter to be sure that the connection is valid. (Refer to LED chart in next section) -10- 10Base-T to 10Base-2 Converter 10Base-2 Connection To connect to an Ethernet using 10Base-2 cable, do the following: 1. Attach the supplied BNC T-connector to the Converter’s BNC connector. 2. Connect one end of a Thinnet (10Base-2) coaxial cable to the BNC T-connector attached to your Converter. Connect the other end of the coaxial cable to the BNC T-connector attached to the Ethernet device. 3. Note: If either your converter or the Ethernet device is an end node, attach a BNC terminator to the open connector on the BNC T-connector. -11- 10Base-T to 10Base-2 Converter Desktop Installation Follow the instructions listed below to install the Converter onto a desktop location. 1. Locate the Converter in a clean, flat and safe position that has easy access to AC power. 2. Affix the provided rubber pads to the bottom of the Converter for grip, and to protect the case from scratching. 3. Apply power to the Converter. (The green PWR LED on the front panel should light). 4. Connect cables from the network partner devices to the ports on the front panel. (The green LNK LED on the front panel associated with the port should light). This Converter can also be mounted on a vertical surface. Simply use the underside of the unit as a template to measure and mark out the position of the holes on to the surface where the unit is to be installed. Then use the two screws provided to mount the Converter firmly in place. Warning Please exercise caution when using power tools. Also, install this unit away from damp or wet locations, or in close proximity to very hot surfaces. These types of environments can have a detrimental effect on the converter and cables. An ideal location is a lightly cooled place such as a typical equipment room. -12- 10Base-T to 10Base-2 Converter Powering On Unit The Converter uses external power supply 12V DC @ 0.5A 50~60 Hz. 1. Insert the power cable plug directly into the receptacle located at the back of the device. 2. Plug the power adapter into an available socket. 3. Check the front-panel LEDs as the device is powered on to verify that the Power LED is lit. If not, check that the power cable is correctly and securely plugged in. Note: For International use, you may need to change the AC power adapter cord. You must use a power cord set that has been approved for the receptacle type and electrical current in your country. -13- 10Base-T to 10Base-2 Converter 4 LED Indicators This Converter has LED indicators located at the front of the device. The LEDs have been designed to give easy at-a-glance network status, and provides ‘realtime’ connectivity information.

This allows for the secure placement of the converter into the Chassis. It also seals off the front of Chassis and allows it to function correctly. Step 1 Using a Phillips screwdriver, remove two screws from the side panels on the converter. Step 2 Place the converter and brackets on a flat horizontal surface as illustrated above. Secure the brackets by replacing the screws. Ensure that the rails are flush-mount with the underside of the converter. The converter is now ready for loading into the Chassis. -16- 10Base-T to 10Base-2 Converter Installing the Converter Once the Converter has been attached to the bracket, it can be installed into the Chassis. Special care must be taken to ensure the correct mating of the power connector. Align the Converter so that it fits between the upper and lower guide rails. Always ensure that the converter power socket is positioned at the base of the Chassis. Never force the Converter into the Chassis - check power socket position and alignment. -17- 10Base-T to 10Base-2 Converter Rear view of Chassis and specifications Rear View of Chassis with AC Power Supply Power: 100 - 240V AC (Optional 12V Adapter) Dimensions: 109 x 174 x 44.3 mm (L x W x H) Rear View of Chassis with DC Power Supply Power: -48V DC (Optional 12V Adapter) Dimensions: 109 x 174 x 44.3 mm (L x W x H) -18- 10Base-T to 10Base-2 Converter Appendix B Application Diagram The following are drawings of typical Applications for the Converter.
