  1. Thank you for the replies. The software I'm using is Modsoft 2.62 to connect to a 984 device and XBT-L1000 with XBT L1MOD01 driver to connect to a Magelis P022010. I've heard that laptops can be a problem. The laptop in question runs Windows 98. What is curious is that the desktop that runs Windows 95 also does not want to connect. I have tried to connect both computers from Dos mode. The laptop is an IBM thinkpad 600e. I've done the Bios upgrade. I will try the suggestions and let everyone know what happens.
  2. I have 2 computers in which the serial port does not work over Modbus. One of them is a laptop and one is a regular PC. Other computers work fine. I use the same cable, same 984 device and try communication from both Windows 95 and from the dos prompt. I suspect it is something to do with the UART type. Does anyone know why this would be. Thanks in advance.
  3. I have a 984 385E I'm trying to communicate with. I was getting error 120 "bad checksum". I believe that was a cable error. I'm now getting error 114, "Unexpected address/function code recieved" I'm using modsoft 2.31 on Windows 95 My cable is 1-n.c., 2-3, 3-2, 4&6 jumpered, 5-5, 7&8 jumpered, 9 n.c. I have the dip switches set as the manual and modsoft describe. I don't find a Modbus port 1 toggle switch on the 385E. Serial Port is set to 9600 baud, 8 bit, even parity, 1 stop, flow control None. Modsoft is set to address (tried ) 1 and 2 etc., RTU, 8 bit, even, 1 stop, 9600 baud, com1 I'm sure there are many out there that have gone thru this. Is there an easy solution? (Laugh) Is there a document that describes the error codes and solutions?

    Tried runing it from Dos but still get error 14. I'm trying to download a new program. Is there any quirks with doing that?
