Hi All,
I am trying to communicate with a Julabo heater controller via an RS485 serial port using LabVIEW. There is a LabVIEW driver that can be found at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=D1216BF0E8613C89E0440021287E65E6 . I am using a USB to serial converter provided by kksystems http://www.aa-kkemail.co.uk/kk-files/usb485.pdf and I have wired a patch cable to match the RS485 connection on page 79 of the Juabo manual (attaached) to the RS485 2-wire connection for the USB to Serial converter, and I keep getting this error, "Error - 1073807252: Overrun error". Can anyone please tell me what I need to do to resolve this?
