New to the forum, but everything looks great! I am trying to get a SLC5/04 channel 0 to communicate via serial to a Mitsubishi A970 GOT HMI. I have the cable pinout from the manual and all the comm settings from the manual but still no go... this is taking too long. The Mitz manual says: DF1 Half-Duplex Slave 19,200 bps (or selected speed) 8 bits 1 stop bit Even parity No control Any help would be great. Thank you.
