Hi and sorry for bad English.
Please help in the use of Modbus and RS485 with Mach3.
Situation: I use RTS for control transmission direction of two-wire RS485. But Mach3 generating RTS signal much shorter then the Modbus request resulting in cutting the request. In pictures: data in, RTS, data out.
