GarrettCom TB14 Media Converter (10 Mb, BNC to Copper)  


• Two models, regular for wiring closets and Hardened for Industrial • Family of power supply types and temperature ratings, AC and DC • Both models provide an internal BNC termination switch and an uplink switch on the RJ-45 • Two sets of LEDs, on beveled facing and on the end, provide status information from any direction • Metal enclosure. Panel mounting, DIN-Rail or Rack-mount tray option


Robust packaging, a selection of extended temperature models, choice of AC and DC power types, ease-of-use features, and energy efficiency are the primary characteristics of the Magnum 10Mb TB14 and TB14H Media Converters. All models offer a graceful way to convert and transmit data between twisted pair and thin coaxial BNC network cables for media flexibility in new or expanded 10Mb Ethernet networks. They provide standard collision detection and indication, and comply with the Ethernet V1.0 / 2.0 specifications and the IEEE 802.3 standards. Power consumed in use is only 3 watts.

The TB14 regular-package units are for wiring closet environments and use an external AC power supply for either 0° to 40°C or the more stressful industrial 0° to 50°C ambient temperature. All power supply units are UL and CE tested and approved for their specified rating. A heavy duty metal case with convection cooling is featured. The units can be mounted securely on a closet wall or the side of cabinet, or by using the metal panel mounting clips included. A rack-mount tray option is available, for up to 16 units.

The TB14H Hardened unit features a sealed metal case which is also used as a heat sink. No air flow is required for cooling, so the TB14H resists dust, dirt, moisture, smoke and insects, and is rated for above-the-ceiling “plenum” applications. Choices of models for external AC or internal DC power are available. Ambient temperature rating is up to –40°C to +75°C depending on the power source used. The TB14H is suitable for temperature un-controlled outdoor applications. Mounting options include panel-mounting, DIN-rail, or rackmount tray.

Magnum TB14 and TB14H Media Converters are designed to provide reliable operation, even in stressed industrial-strength and “outdoor” applications environments. Their high-strength fabricated metal packaging shields against Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI). Like all Magnum Ethernet connectivity products, they are backed by a three year warranty.
