Model 9271 - DB9 Fiber Optic Line Driver
The Model 9271 DB9 Fiber Optic Line Driver features a standard DB9 interface for maximum performance and reliability of data transmission over glass fiber, eliminating the need for serial to nine-pin adapters. In addition, it brings effective data communications to manufacturing environments. It can be installed in applications requiring very high data transmission rates, offers resistance to Electromagnetic Interference (EMI), and isolation from lightning-induced current surges and ground loops. The unit employs an RS-232 data interface, can achieve 115.2 kbps asynchronously and operates in either half- or full-duplex modes over dual fibers up to 2 km in length.

The Model 9271's ability to take/direct data from/to this interface without any conversion eases implementation. A highly flexible solution, the Model 9271 has been optimized for 62/125 fiber cables, and is compatible with other sizes as well. It features industry-standard ST cable port connectors, plus a DTE/DCE switch to reverse Pins 2 and 3 of the RS-232 connector to accommodate equipment with different data output configurations.

Operating current for the Model 9271 is derived from the transmit data line, with a power budget of 12 dB when using 62/125 cable. For applications requiring a dedicated power source, the unit can be ordered with a wall-mounted power pack (available as the Model 9271A).

The Model 9271 incorporates clips in the outer casing so that the unit can be securely attached to a DIN rail, wall, table or desk in an organized manner.

Model 9365 - DB9 RS-422/RS-485 to RS-232 Tri-mode Interface Converter

Model 9365
 DB9 RS-422/RS-485 to RS-232
Tri-mode Interface Converter

 

 

The Model 9365 is a cost-effective solution designed to enable networks using the latest DB9 interface connections to seamlessly communicate between RS-485 or RS-422 devices, and RS-232 equipment at data rates up to 115.2 kbps. Its Tri-Mode capabilities provide ultimate flexibility for user-selectable conversion between RS-232 and either RS-422 or RS-485 devices, while its new reengineered design permits an easy snap-on connection to standard DIN Rails.

The Model 9365 addresses these needs by allowing for user-selectable conversion between RS-232 and either RS-422 or RS-485 in one small box. For added versatility, it offers an "intelligent" mode to control the RS-485 line, and may be configured as either a two-wire or four-wire converter. Further flexibility is achieved for RS-485 conversion applications using half-duplex protocol-the unit can be configured to control data flow using the RTS (Pin 7) of the RS-232 port, or only when TD data is applied to the RS-232 port.

A static LCD display provides confirmation of data transfer between connected devices. Useful during installation, testing and whenever there are suspected conversion problems, the graphic display presents users with real-time status of the Transmit (TD) and Receive (RD) Data signals, as well as CTS, RTS, DSR, DCD, DTR control signals.

The Model 9365 incorporates clips in the outer casing so that the unit can be securely attached to a DIN rail,wall, table or desk in an organized manner.

Model 9268 - RS-232 Opto Isolation Module with DB9 Connectors

Model 9268
RS-232 Opto Isolation Module

 

Ensure clean data transmission and reception between two devices by installing Telebyte Model 9268 Opto Isolation Module with DB9 Connectors. For applications ranging from testing laboratories to factory floors, isolation is a critical component in data communications environments. Minimize the occurrence of data errors, voltage spikes and system faults while providing full duplex, optically isolated signal paths for both TD and RD, and a control signal pair selected by internal jumpers (CTS, RTS, DCD, DTR). 

The Model 9268 protects against ground loops between devices that use different power sources, generate dissimilar ground currents or produce noisy signals for data rates up to 115 KBPS. Equipped with a standard DB9 interface for direct connection to the latest computer hardware, the Model 9268 is designed to protect against these problems in a smaller form factor than 25-pin serial connections.
