I would guess that it's possible some of the ancillary control lines in your USB-RS485 interface are being set up differently on each computer. One difference is that the problematic laptop had a previous version of the driver installed. We are working diligently to get this fixed.

Actual data for why developers shouldn't test their own code? The program can create a data flow, wrap it to data packets (RS232, TCP/IP or UDP) and send to a port ComEmulator.zip 3.43MB RealTerm Advanced Serial terminal capturing, controlling and debugging Worth the little extra $$$ as well. The db9 to terminal bus adapter is well labeled and I had no problem wiring it to the controller correctly.
There are less expensive options, but this is a very reliable one Add a review Cancel reply Your email address will not be published. With a terminal board connector included, this small, portable, and convenient solution is a must have tool. Two of these operate at RS232 voltage levels – these can be used as a direct replacement, with no PCB changes, in a system which uses RS232 levels, while four of Usb To Rs485 Converter Moxa Yes, pretty bad workaround.

The defaults are stored using a whole set of registry keys, but I would recommend manually setting all the port configuration options every time you open the interface, even if you Usb To Rs485 Converter Cable All prices include duty and customs fees on select shipping methods.Incoterms: DDU applies to most non-EU customers.Duty, customs fees and taxes are collected at time of delivery. In some cases they can reduce system costs by removing an RS232 level shifter from a design. The sensors would be deployed on a multidrop bus that provided both RS485-based communications with the master controller and power.

I don't know why these RS-485 to usb are so pricey, perhaps it's the FTDI chip. Usb To Rs485 Converter Radio Shack Please confirm your currency selection: Euros Euros are accepted for payment only in EU member states these countries. The cables include FTDI’s FT232RQ USB to serial UART interface IC device, which handles all the USB signalling, and protocols, plus an appropriate transceiver.
I recomend this item to anyone involved with serial communications. Do not show again and take me directly to the Basket. This feature is temporarily unavailable. Zt485een RS485 is an electrical specification for a shared bus, and this little device handled the electrical signals and my bus protocol flawlessly.
How to bound locator icons and change their appearance? It seems older laptops with Centrino stuff work, so far no newer laptop with Intel i5/i7 CPU worked. The working laptops have a jitter of max. 1 microsec. his comment is here However, I bought a USB-ExpressCard (sorry, German webshop) with Renesas USB 3.0 chipset and with that the Fujitsu laptop worked just fine.
