BlackBox ME890A-R2 Async RS-232 Extender Over CATx

BlackBox, ME890A-R2, Async RS-232 Extender Over CATx, DB9 with Control Signals

These CATx Line Drivers enable the user to place a receiving device up to 4000 feet away from the sending device. The local unit has a DB9 female connector and is configured as a DCE device; the remote unit has a DB9 male connector and is configured as a DTE device. This allows the local/remote pair to function as a long extension cable between two RS-232 devices. There are no user-configurable settings. These units pass TXD, RXD, RTS, and CTS signals to allow application to use hardware handshake signals if neccessary.

Features:

• Signals include RD, TD, RTS, CTS, GND, plus DTR (or DSR) asserted.
• Local and remote units can be up to 4000 feet (1250 m) apart.
• Fixed DCE local and DTE remote
• Operates point-to-point in full-duplex mode
• Provides 1000-VDC isolation between RS-232 interface and RS-485 interface
• Requires one external power supply (included) at each end.
• Supports data pair plus one control pair, and asserts one additional control line
• Use long-distance CATx links to communicate with serial devices.
• Control presentations remotely.
• Transfer data between computers.
• Ideal for a wide variety of applications.
• Optical isolated.
• Maximum speed of 250 K.
• Easy installation. The driver provides full-duplex transmission and hardware handshake signals. There's no need for setup or configuration.
