Not quite. 1. The PC motherboard has Ethernet already so no extra card needed. 2. From there the regular Ethernet cable goes to the MESA 7i92H which also needs 5V. 3. From the MESA 7i92H two ribbon cables with parallel port type DB25P go from the 7i92H to the PMDX126 and a far east BoB I bought through Aliexpress for $4. 4. The BoB connects to the motor drivers, switches relays etc. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
