The program i am using to receive the signals is python. This is what I am receiving from my program. Message[192.168.0.199:10002] - &F#002222Nti01:10/id098/pi010/OPA UNSET MGR. - 0x26 0x1 0x0 0xf 0x46 0x23 0x30 0x30 0x32 0x32 0x32 0x32 0x9a 0x16 0x4e 0x74 0x69 0x30 0x31 0x3a 0x31 0x30 0x2f 0x69 0x64 0x30 0x39 0x38 0x2f 0x70 0x69 0x30 0x31 0x30 0x2f 0x4f 0x50 0xa4 0xf 0x41 0x20 0x55 0x4e 0x53 0x45 0x54 0x20 0x20 0x20 0x20 0x20 0x4d 0x47 0x52 0x2e 0x9e 0x7f 0x97 I have checked what opengalaxy is responding with and it appears to be x00 x38 xC7 , but when I add this as a reply by my program it does not acknowledge the signal, I have tried other combinations including 0x1 0x41 0x6 0xb9, 0x1 0x6 0x41 0xb9, 0x0 0x41 0xbe but with no look, but I am clutching at straws. The initial signal I receive is 0x5 0x1 0x0 0xd8 0xc1 which is acknowledged with 0x50 0x1 0x0 0x6d 0xff , not sure why I am receiving this but it does appear to work. Thanks Andy

Hi DKlemm, I am working on a similar thing but I am also struggling to figure the ACK message, can you give me a bit more information on how you calculate the correct acknowledgement message, I have figured the last bit being a parity check using column parity but I am unsure which function code or message to use, it appears the opengalaxy sends in blocks but under udp it just seems to transmit the whole string with different function codes throughout the message. Many Thanks Andy
