Network & Communication

Convert async RS232 to RS422/485 at speeds up to 19.2 kbps with distances up to 4000 ft over CATx cables. These devices are great for connecting RS232 devices into an existing RS422/485 environment in factory automation, building automation, and process automation. They can be mounted using DIN Rail and can withstand operating temperatures of -40 to 176 degrees F (-40 to 80 C).

• Tolerates temperatures ranging from -30 to +185° F (-40 to +85° C).
• Designed to withstand both shock and vibration.
• Boasts 2-kV triple isolation for safeguarding data and equipment.
• Supports fiber ring communications with 31 other units.
• Data rates up to 115.2 kbps.
• DIN rail mountable with an optional adapter.

Our premium Industrial Opto-Isolated Serial to Fiber Multimode ST Converter is the ideal choice if you need reliable serial data extensions in heavy-industry areas.

Meets stringent IEC and IEEE specs.
Encased in an IP30-rated enclosure, the converter's been put through some of the most exacting tests in the industry. The high-grade converter meets the requirements of two standards that make it suitable for electrical substation installations - IEC 61850-3 and IEEE 1613 - specifications that are more stringent than NEMA TS1/TS2 requirements for transportation applications.

Plus, as a fiber-based conversion and extension device, it's inherently immune to electromagnetic and radio-frequency interference (EMI/RFI) as it uses the optical cable to extend RS-232, RS-422, and RS-485 serial data as far as 2 kilometers (1.2 m.).

Three levels of isolation.
The Industrial Opto-Isolated Serial to Fiber Multimode ST Converter provides powerful isolation. Featuring 2-kV triple isolation, the device protects equipment as well as data from damaging surges and ground loops. With isolation on the converter's power supply circuits, you're given a third degree of protection for your expensive components.

This level of protection helps prevent rogue currents from disrupting important data communications, such as those in the factory, engineering, military, defense industry, or utility applications.

By isolating voltage anomalies, you stand a much better chance of preventing a surge from shutting down an assembly line - or your entire plant.

Use in point-to-point or multipoint applications.
You'll need two units for a standard point-to-point application. But you can also easily set up a multidrop configuration so one serial device talks to multiple slave devices around a fiber ring.

Used in a fiber ring type of application, one Industrial Opto-Isolated Serial to Fiber Multimode ST Converter can communicate with up to 31 other converters in a ring.

The converter has a removable terminal block for both RS-422/RS-485 and power connections, and it supports serial Modbus® connections for both ASCII or RTU (remote terminal unit) formats.

Simple to configure and set up.
DIP switches enable you to configure the converter for a multidrop or point-to-point operation, and a serial mode switch enables you to choose RS-232 or RS-422/RS-485 modes.

For additional ease of setup, bit-wise enabled circuitry detects the data rate automatically without you having to set a DIP switch. An automatic send data control feature enables an RS-485 serial port to be used in Windows® applications where you have no control over the handshake lines.

In addition, the Industrial Opto-Isolated Serial to Fiber Multimode ST Converter has built-in switchable bias resistors (1.2 kilohms) on transmit and receive ports, as well as switchable termination (120 ohms).

The Freedom II KM Switch with Glide; Switch enables a single user to easily access information and control operations across the computer systems and monitors, saving time, money, and space. The Freedom II works like an extended desktop switch on a single computer. Once you configure your screen layout for the attached PCs with up to four external displays, switching ports is as simple as moving your mouse cursor over the screens' X and Y borders.

Freedom is ideal in command and control applications, such as those in finance on a trading room floor. Not only can users switch between several computers just by moving the mouse, but they can also simultaneously access a mix of USB peripherals, including high-speed USB 2.0 devices.

Additionally, the Freedom II KVM Switch integrates with the Black Box Agility IP-based KVM system. This Freedom II KM Switch can interface with Agility receivers, and then switch the Agility targets using just one keyboard and mouse.

The Freedom II KM Switch is ideal for command and control applications such as in:

• Broadcasting
• Public safety
• Industrial
• Defense
• Transportation
