Hi All, This is my first post on this list, and I am a relative newcomer to Linux, so please excuse me if any of my questions seem a bit "basic"... I'm an Anaesthetist from Australia (the Americans on the list would call that an Anaesthesiologist) so programming is more of a hobby than a job. I am trying to develop some software to pull down information from a piece of patient monitoring equipment in the operating room to a laptop running Ubuntu Linux 12.04. The patient monitor speaks to the external world over a RS-232 Serial Port. I have information about the protocols and formats etc. to communicate with this device. What I need is advice regarding a suitable USB-Serial port adapter, as my Linux laptop does not have a serial port. There are further constraints in the system - it would be very desirable to have a USB-Serial port adapter with "medical grade galvanic isolation on its serial lines". As far as I can see, only Digi has this. I am particularly interested in the following models of Digi USB-Serial port adapter : 1. Edgeport/4s MEI Isolated - 4 RS-232/422/485 serial DB-9 software selectable with galvanic isolation (Part # 301-1000-95) http://www.digi.com/products/model?mid=2690 2. Edgeport/2c - 2 RS-232 serial DB-9, captive 2-meter cable (Part # 301-1003-10) http://www.digi.com/products/model?mid=249 (the former has the proper electrical isolation for "production use" while the latter does not, though it is more compact and will be used for development where the monitoring equipment is not connected to a patient) Can anyone tell me whether these two USB-Serial port adapters are supported by Ubuntu Linux 12.04 ? (The Digi datasheet for these products says "Driver support provided by Linux USB maintainers" in reference to Linux Support) (The Ubuntu website says that the 12.04 LTS Release ships with the Ubuntu 3.2.0-23.36 kernel which is based on the v3.2.14 upstream stable Linux kernel) Are there specific drivers required or is there an applicable generic driver, and would I have to find this and install it, or is it built into the kernel ? Could I expect relative smooth sailing from a driver/hardware compatibility perspective ? Thanks in advance for any advice.
