GPIB-RS232, Serial, RS232 GPIB Instrument Control Device - Universal Euro 240VAC
779732-04
The GPIB‑RS232 is an IEEE 488 controller device for computers with an RS232 port. You can use this device to integrate an instrument into your system using GPIB. This device transforms a computer with an RS232 serial port into a talker, listener, or controller on the GPIB bus. It can also interface RS232 instruments and peripherals to the GPIB bus. It can implement the physical and electrical specifications of the IEEE 488 and RS232 standards, as well as interpret and execute high-level commands from the serial port, including RS232‑to‑GPIB and GPIB‑to‑RS232 protocol conversions. This device is IEEE 488.2 compatible. The device includes a license for the NI‑488.2 driver software, providing maximum reliability for connecting to third-party instruments with GPIB.

RS232 / RS485 / RS422 / Serial To Multi-Drop Fiber Optic Converters
Our advanced, rugged, industrial-grade, RS232 / RS485 / RS422 serial to multi-drop fiber optic converters are designed to cover large areas. These converters support up to 255 fiber nodes, and each fiber node can extend the RS232 / RS422 / RS485's distance to 3 miles (5km) for multi-mode converters and cables, or 25 miles (40km) for single-mode converters and cables. Depending on the site situation, these multi-drop fiber optic converters can be configured as a daisy-chain or a self-healing redundant ring fiber network. When configured as a ring fiber network, the built-in self-healing feature allows the data to be transmitted clockwise or counterclockwise; therefore, failure of any individual converter will not affect other devices located on the same fiber ring, making the entire data network more robust and reliable. These multi-drop fiber optic converters have been designed for harsh industrial environments and withstand a wide temperature of -40°F to 185°F (-40°C to 85°C), and they come with the options of multi-mode and single-mode, and ST, SC, and FC connectors.

Fluid Level Sensor
The output of the fluid level sensor is a voltage which changes in direct proportion to the level of fluid in the probe. The difference in permittivity between air and the fluid being measured changes the capacitance between the probe's two concentric tubes as the level changes. An RS232 connection to a PC allows the user to calibrate the fluid level and thermal drift compensation. The probe is factory replaceable, allowing the electronics to be re-used should the probe become damaged or if a new probe length is required.
