Hi I have a client who is interested in a YUMA 2 but is concerned that it doesn't have a serial port. Is the available serial port adapter easy to use, stable and reliable when using a serial device? He is wanting to use it as he needs a Windows based platform for recording geophone locations and programming and downloading data from seismometers. Some of the seismometers use RS-232 serial and their software is not keen on working via USB to Serial adapters to date. On the YUMA 2, is there any way to connect via a wired RJ-45 Ethernet connection as some of his seismometers need this? Also, on the original YUMA, does the built in serial port have standard interface chips working directly on the I/O bus or is it working via the USB hardware? Finally, is there available or going to be available a vehicle docking station for the YUMA 2?
