The 232OPDRI-PH is our premium Heavy Industrial RS-232 Isolated Repeater. Designed for rugged industrial environments, it has been put through some of the most exacting compliance tests in the industry. Meeting the requirements of IEC 61850-3 and IEEE 1613, it is suitable for installation in electrical substations. These specifications are more stringent than the NEMA TS1/TS2 requirements for transportation applications. Powerful isolation on both data ports protects your equipment and data from damaging ground loops and surges. Additional isolation on the power supply circuits adds a third degree of protection.

The Universal Serial Data Splitter can be connected so that any two RS-232 devices can be connected to any one RS-232 device. Nine pins are supported: pins 1-8 and 20. Pins 1 and 7 on all three connectors are connected to each other at all times. The other pins must be programmed for proper direction of data flow.
To program the data flow direction requires some knowledge of how your ports are wired. If you are trying to connect two devices to one DCE port (such as a printer) switches 8, 6, and 2 should be on and the other switches off. This OR's the data on pins 3, 5, 6, and 8 together and sends it out the main connector, and allows the data on pins 2, 4, and 20 to flow the other way.

These compact USB to Asynchronous Serial RS-232 and RS-485 mini-converters allow you to add a serial port to your USB only PC. They are perfect connecting to a remote device to gather data or upload a program. USB 2.0 compatibility makes installing them on your PC easy. Versions are available with DB9 connectors and Terminal Blocks for quick wiring. We support RS-232, RS-485 (2-Wire) and RS-485 (4-Wire) protocols. Need 5 Volt and 3.3 Volt TTL? We even have a converter for that. Our driver software supports operating systems up to Windows 7 with 32 and 64 bit support.
