It appears the text for the channels has a colon character that's messing up the way the data is read over the network. I was able to resolve this by modifying the AVB8NA.lau file and replacing the lines:
ExportScript.Tools.SendData(2023, string.format("%s", lUFC_Chnl1)) -- string with max 2 charachters
ExportScript.Tools.SendData(2024, string.format("%s", lUFC_Chnl2)) -- string with max 2 charachters
with:
ExportScript.Tools.SendData(2023, string.format("%s", lUFC_Chnl1:gsub(':', ''))) -- string with max 2 charachters
ExportScript.Tools.SendData(2024, string.format("%s", lUFC_Chnl2:gsub(':', ''))) -- string with max 2 charachters
