Hello. I have purchased a used Deco 20a with transmit function option and C-axis. But when I try to use a program using transmit function (M198 D-1) the machine alarms and says option not installed. I have checked the required keep relays. What else am I missing? I spoke to Tornos US and they said I need to buy the option and I said the machine already has the option. The new EVO Deco 32 I bought came with the option for no charge. They are trying to nickle and dime everything.
