Hi friends,
I know that this question already was talked but, in my search, this dont be clear. I have to connect Micrologix 1400 to RS485 modbus rtu network.
1 - I know that the 1763-NC01 is the most safe option, but I dont have and wont buy it now.
2 - Can I construct my own cable just pin-out, without resistors? Wich is the reasons that it can damage the equips?
3 - The cable has 15 cm max, and I can use low baud rate......
4 - If is extremaly nescessary to use a terminator resistors, what is its impedance and is just solder between a-b terminals?
5 - About this document posted here:
1763-NC01 Cable Connections:

the image is confuse. For I understand: the pin 8A of conector drawed at the document, is the top or bottom 6-7-8 pin looking in front of PLC mini din port?
Thanks very much.
