Please set the DPT for the channel:

Bridge knx:ip:bridge [ 
    ipAddress="192.168.249.103", 
    portNumber=3671, 
    localIp="192.168.249.114", 
    type="TUNNEL", 
    readingPause=50, 
    responseTimeout=10, 
    readRetriesLimit=3, 
    autoReconnectPeriod=1,
    localSourceAddr="0.0.0"
] {
    Thing device generic [
        address="1.0.5",
        fetch=true,
        pingInterval=300,
        readInterval=3600
    ] {
        Type switch : UG_Gang_Licht "Light" [ ga="1.001:1/0/200+<1/0/201" ]
    }                                          // ^^^^^^
}

as there is a problem that DPT is not optional when using more than one GA per parameter.
