RS232 / RS485 / RS422 / Ethernet Surge Protectors
-
Our passive, rugged, industrial-grade RS232 / RS485 / RS422 / Ethernet surge protectors are designed for direct industrial DIN-rail mounting and they come with two (2) or three (3) stages of surge protection — Gas Discharge Tube (GDT), protection resistors, and Transient Voltage Suppressor (TVS) - for maximum protection. From 2-wire RS485, 4-wire RS422 / RS485, to 10 / 100 / 1000M Ethernet, CommFront's surge protectors safeguard your data lines and provide you with a peace of mind.

Free Serial-TCP (More Than Just A Device Server)
-
In the past two decades, legacy serial communication protocols such as Modbus have merged rapidly with modern TCP/IP communication, yielding benefits including widely available infrastructures and greater distance, reliability, and speed. The Serial-TCP program (more than just a Device Server) bridges your existing Serial COM port and TCP/IP without the need for changing existing protocol. It works seamlessly and transparently, just like passive RS232 / RS485 / RS422 converters, repeaters, and hubs, while the difference is that one requires installation of cables and converters with limited distance; and the other simply makes use of the existing computers and networks with an unlimited transmission distance

USB Extenders / Repeaters / Hubs
-
CommFront has all the solutions that you need to make your data travel seamlessly without limits. We offer a range of rugged, industrial-grade USB extenders (repeaters) and hubs to meet your data communications' distance needs by converting unbalanced signals to balanced ones, deploying repeaters to boost signal strength, and implementing hubs for star-configured connections, while still taking full advantage of cost-effective and readily-available copper wire.
