Description

RS-232 to Current-Loop Interface Bidirectional Converter (232/CL-E), AC-Powered, Active or Passive, Standalone

Quick Facts

Connect your Current Loop equipment to an async RS-232 device.

Configure this AC-powered converter to match your system’s 20-, 30-, or 60-mA Current Loop interface.

Has built-in optical isolation on the receive pair.

Further Details

Optical isolators in both the Transmit and Receive loops keep out electrical interference.

AC-powered, active or passive.

With front-panel LEDs, you always know the status of your data. The easy-to-use self-test feature checks the converter’s internal circuitry.

Connect this converter to either a modem or mux. Just flip the switch to attach a terminal or computer. Your RS-232 devices are protected from dangerous transients, too.

What's included:
　

(1) 6-ft. AT® Modem Cable (EVMBMC-0006)

(1) DB9 Male to DB25 Female AT Adapter (FA521A-R3).

Black Box Explains...RS-232..

RS-232, also known as RS-232C and TIA/EIA-232-E, is a group of electrical, functional, and mechanical specifications for interfaces between computers, terminals, and modems. The RS-232 standard was developed by the Electrical Industries Association (EIA), and it defines requirements for connecting data communications equipment (DCE)—modems, converters, etc.—and data terminal equipment (DTE)—computers, controllers, etc.) devices.

The standard, which is functionally equivalent to ITU V.24/V.28, specifies the workings of the interface, circuitry, and connector pinning. Both sync and async binary data transmission fall under RS-232. Most PCs use the RS-232 interface to transmit data to modems, and some printers even use it.

Although RS-232 is a “standard,” you cannot necessarily expect seamless communication between two RS-232 devices. Why? Because different devices have different circuitry or pinning, and different wires may be designated to perform different functions.

The typical RS-232 connector is DB25, but some PCs and other data communication devices have DB9 connectors. To connect 9-pin PC ports to devices with 25-pin connectors, you need a simple adapter cable. The most commonly used interface, RS-232 is ideal for transmitting data at speeds up to 20 kbps and over distances up to 50 feet (15.2 m).
