Using RTS for transmit RS485
« on: December 26, 2010, 06:12:58 PM »
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.

Question: What can I do to fix this?
