Model 9080 is an RJ45 A/B/OFFLINE Cat5e Compliant Network Switch, DIN Rail Mounted that allows users to share one RJ45 device among two others or to isolate all ports by switching to OFFLINE position.

The PathWay® Model 7465 RJ45 8-Channel A/B Network Switch with 10/100 Base-T LAN Telnet Access allows sharing a device connected to the COMMON port among two other devices connected to the A and B ports for each channel

Model 4177 is a high speed ruggedized USB to RS485/422/232 Interface Converter that converts 2.0 compliant data from a standard PC to a serial asynchronous data interface over RS232 or RS485/422 Networks.

The Model 4176 is a high speed, ruggedized USB to RS485 / 422 / 232 Interface Converter that converts USB 2.0 compliant data from a standard PC to a serial asynchronous data interface over RS232 or RS485/422 networks.

With its integrated rate buffering, the Model 4165 converts USB 2.0 compliant data from a standard PC to a serial asynchronous data interface over fiber with a user-selectable baud rate of up to 3 Mbps.

Model 4163 hi-speed ruggedized Ethernet-to-RS485/422/232 converter converts Ethernet 10/100 Mbps IEEE 802.3 data from a LAN/WAN connection to a serial asynchronous data interface over RS232 or RS485/422 networks with a baud rate of up to 921,600 bps.

Models 4162 and 4169 comprise a Host and a 4-Port Hub that extend USB connections via a high speed Fiber interface. The units convert USB 2.0 compliant data from a standard PC Host interface over fiber to a remote 4-Port powered Hub.

The Model 4149 media converter is a very high speed ruggedized Fiber to RS485/422/232 interface converter. Typical operating speeds: Up to 1.5 Mbps for RS232 to fiber conversion, Up to 5 Mbps for RS485/422 to fiber conversion.

Model 4173 with built-in fiber optic / copper medium conversion allows access to two separate fiber optic ST ports (ports A and B) from a Fast Ethernet RJ45 port. This switch is ruggedized for vibration environment.

QuickSwitch Model 4181 SC Duplex 100BaseFX Auto Fallback Switch with Remote access can increase network uptime by automatically detecting a faulty line and switching to a backup/secondary fiber optic network.
