Minnetonka, Minn., September 13 /Marketwire/ -- Transition Networks Inc., the fiber networking expert, a wholly owned subsidiary of Communications Systems, Inc. (NASDAQ:JCS), today announced the availability of the "mini" Industrial Media Converter. Answering the need for media converters that fit into compact environments, the addition of the Industrial Mini to Transition Networks' already vast industrial portfolio enables customers to extend 10/100 Ethernet networks to devices in remote, space-constrained environments without the need for environmental controls. This allows organizations to experience the benefits of Ethernet while saving money and time on infrastructure and environment redesign.

With industry-leading features such as Auto-Negotiation, AutoCross^TM, Link-Pass-Through, Automatic Link Restoration and Far-End-Fault, the Industrial Mini is a plug-and-play solution for transparent insertion into any existing network. Backed by Transition Networks' unsurpassed Lifetime Warranty, this budget-conscious networking device is built to operate trouble-free in harsh outdoor or industrial environments.

"As Ethernet continues to proliferate into many different applications and environments, we're seeing the importance for a variety of different form factors to accommodate space and temperature requirements," said Patrick Schaber, Director of Marketing at Transition Networks. "For example, many cities, transportation systems, utilities and ports are now deploying large, Ethernet-based, video security networks in outdoor locations. The Industrial Mini is an ideal solution for bringing Ethernet to small, confined spaces such as housings in camera installations."

The Industrial Mini will operate over a very wide temperature range of -40°C to +75°C. The unit's terminal block accepts a wide12 - 48VDC power input with reverse polarity power input protection and overload current protection. The small power consumption of just 2.5W further lowers system cost by minimizing heat generation within small enclosures. To further ease installers' jobs the Industrial Mini comes with an installation kit consisting of a DIN-rail bracket, Velcro strips and a DC power barrel connector. A wall-mount bracket and AC-to-DC power supply are offered as optional, labor-saving accessories.

The Industrial Mini is available now in the following Transition Networks models:
