Trouble reading the Radio

Feb 8, 2018
Hello All,
I am new to this forum and to the hobby in general, but do have a bit of a background in electronics.

First, some caveats. I own the software, radios and license.

My problem, I am attempting to read and program some Vertex Standard VX-310 H/T radios. I have 8 of them that I would like to distribute to family members. We have a GMRS repeater in our area that we have permission to be on and I am attempting to get these radios programmed to work on the repeater and simplex. I am using both a Windows XP desktop with a serial cable and a USB cable with the FTDI chip. I have also attempted to use a Windows 10 64 bit laptop with the USB cable. The cable is made by maxtop and is supposed to be for this particular radio. The software has installed on both computers without issue and the radios were placed into program mode by placing the rotary position to 14 and holding down the aux and f1 buttons while turning on the radio. The display remains blank and the light on top turns red/orange. There is an immediate error when attempting to read the radio that reads, "Failed to Read Out. Try Again."
Is there anyone out there that can help with this? I have verified that the port is assigned correctly and I set the baud rate to 4800 to try to help it. Any help would be much appreciated.
