Page7 Press the CW button to set the controller in the Serial Receive mode The controller now waits for data from the host computer Next go to your PC and using your serial communications application start the serial data transfer The Red LED will flash as data is received from the PC and after successfully receiving the data the controller will save it to nonvolatile memory and then returns to the default Manual Operating mode You can verify proper memory programming by either manually stepping through the memory channels and verifying the Memory Labels are correct and the antenna moves to the count that was edited in the text file or resend the serial data as explained above and compare the new capture to the data that was previously sent to the controller If the data file is not formatted properly the data transfer will fail The serial protocol is very simple and there is limited error checking and correction provided in the controllers programming In the event that the Receive function fails power cycle the controller to clear any hang condition If something fails in the transfer the controller will appear to hang as it may be waiting for data or the transfer file has an error in its format Again a power cycle will clear the hang condition Data Format The data sent and received is a simple 346 byte ASCII file with the following format Start Character Call Sign Text 8 Characters Text Memory Channel 012. 8 Character Label xxxx Memory Channel 02 8 Character Label xxxx Memory Channel 24 8 Character Label xxxx End Character Where xxxx ASCII Numeric Count All data fields are separated by a comma All Message fields are 8 characters and all count fields are 4 characters so leading Os are required for values under 1000 i e 0014 The Start Character of must be the first value sent and the End Character of must be the last character sent The start and stop character should not be used in user entered text in the modified text file as it will cause the transfer and save operation to fail Example Text File 12345678 160Mtr L 0120 160Mtr H 0115 80Mtr L 0110 80Mtr H 0105 60Mtr C1 0100 60Mtr C2 0095 60Mtr C3 0090 60Mtr C4 0085 40Mtr L 0080 40Mtr H 0075 30Mtr L 0070 30Mtr H 0065 20Mtr L 0060 20Mtr H 0055 17Mtr L 0050 17Mtr H 0045 15Mtr L 0040 15Mtr H 0035 12Mtr L 0030 12Mtr H 0025 10Mtr L 0020 10Mtr H 0015 6Mtr L 0010 6Mtr H 0005 FTDI Driver Requirements To use the onboard USB interface your computer needs to have the FTDI Virtual COM Port driver loaded This driver is available on the FTDI Web Site at the following URL http www ftdichip com Drivers VCP htm From this location select the driver based on you Operating System and install as instructed by FTDI Connection Information The provided cable is a 4 conductor 18 Gauge 7 s
