I am writing a VB5 program for the MU80 and have a problem 'talking' to the device from the PC. The connection is there, but I keep getting 'Ilegal Data' error messages. I am not sure if this is in the Com Port settings or in the format of the data that the MU80 receives. Judging by VB5, it would appear that the data is a string format.

Would anyone know the communications and data parameters used by the MU80 to receive via the to-host PC2 port?

Many thanks.
