Jupiter Fusion 980 - Rx Issues

  Are you using a serial cable that ONLY has pins 2, 3, 5, 7 & 8 passed through? If you have a cable with more than those, there's a good chance you're mucking up the com port on the Jupiter. What about handshaking?

  The cable I was using originally was just pins 2,3,5 with 2 and 3 swapped. I used the null modem cable that came with the jupiter later on and got the same results. I should also clarify that when I connected the jupiter directly to my laptop and was able to receive strings back from the jupiter, I was using the null modem cable. I couldn't use the other cable because it was tied into the rack.
  As for handshaking, I am also sending the 'HSOFF' command.

  When I was working on a Jupiter 960 I had to send a CHARD250 command to it to create a long character delay before it would work. The serial interface in the Jupiter was so bad that I eventually converted to connecting via IP.

  I am trying to set it up via IP now, but I'm not having very much luck. I have very little experience with communicating over IP. Does this look ok?
  
  DEFINE DEVICE
  dvJUP = 0:2:0
  dvNI = 0:3:0
  
  
  
  DEFINE START
  GET_IP_ADDRESS(0:0:0, MyIPAddr)
  IP_SERVER_OPEN(dvJUP.Port,25456,1)
  IP_CLIENT_OPEN(dvNI.Port,MyIPAddr.IPAddress,25456,1)
  
  I am using a Linksys wireless router w/ IP: 192.168.50.1
  The Master is: 192.168.50.254
  The Jupiter is: 192.168.50.114
  I was able to ping the master from the Jupiter.
  
  Also, I set up Diagnostics to monitor strings on 0:2:0 and 0:3:0 and I'm not seeing any strings being sent.

  No, that bit of code will connect the NetLinx that the master to itself ... I don't think that's what you are going for . Get rid of the dvJUP device, and get rid of the GET_IP_ADDRESS and IP_SERVER_OPEN lines. Make a CHAR variable to store the IP address, and use that in IP_CLIENT_OPEN.

  DEFINE_DEVICE 
  dvNI = 0:2:0
  
  DEFINE_VARIABLE
  
  VOLATILE CHAR sIPAddress[]  = {'192.168.50.114'}    // Jupiter IP
  
  // Connect code ... I wouldn't put this in DEFINE_START. Attach it to an event or create a
  // Timeline that will attempt to re-connect as long as the connection does not exist.
  
  IP_CLIENT_OPEN(dvNI.Port, sIPAddress, 25456, 1)

  Here is the code that I used to make it work:
  
  (Sorry about the lack of formatting - I keep forgetting how to get it in one of those nifty little code boxes.)
  
  dvJUPITER1 = 0:2:0 //Jupiter 1 - TCP/IP connection
  
  DEFINE_START
  
  IP_CLIENT_OPEN(dvJUPITER1.PORT,'192.168.1.10',25456,1)
  
  DATA_EVENT[dvJUPITER1] // TCP/IP VERSION
  {
  ONLINE:
  {
  nJUPITER1Online = 1;
  WAIT 20
  {
  SEND_STRING dvJUPITER1,"'Admin',13,10"
  WAIT 20
  {
  SEND_STRING dvJUPITER1,"13,10"
  }
  }
  }
  
  OFFLINE:
  {
  nJUPITER1Online = 0;
  // Attempt to re-establish communications
  IF (nJUPITER1KeepOpen)
  {
  WAIT 300
  {
  IP_CLIENT_OPEN(dvJUPITER1.PORT,'192.168.1.10',25456,1)
  }
  }
  }
  ONERROR:
  {
  SWITCH(DATA.NUMBER)
  {
  // No need to re-open socket in response to following two errors.
  CASE 9: // Socket closed in response to IP_CLIENT_CLOSE
  CASE 17: // String was sent to a closed socket
  {
  }
  DEFAULT: // All other errors. May want to re-try connection
  {
  IF (nJUPITER1KeepOpen)
  {
  WAIT 300
  {
  IP_CLIENT_OPEN(dvJUPITER1.PORT,'192.168.1.10',25456,1)
  }
  }
  }
  }
  }

  Ha! I eventually figured it out (I tried modifying an example from the AMX programmer's course guide). I haven't done IP since the programmer II course, but I always knew I'd have to do it eventually. It's working great now, no more hang ups and I'm getting responses back. Thanks for the help!
