I have one of these and, for me at least, it is good value for what I paid.
The PC software is v6.0 and the firmware is v3.3 and seems to have provision to update the firmware on line.
I have discovered one problem - the PC S/W only talks to CON1 to CON16 - my system goes up to 24!! so using it requires a certain ammount of "fafing" about to get it to connect. It does have an "autoconnect" feature but it dioesnt seem to work above 16.
Has anyone found a way to report such bugs
TIA and best regards,
Dave
