Hello all,
I joined this forum because I saw there was discussion about the 8 Pin Mini DIN connector on Allen Bradley. I am trying to connect RS-485 comms to other devices. We wish to use the existing port rather than add another Isolator module. We are implementing Modbus using the Micro 830 processor
Standard 8 pin mini dins seem to have different keyways then the connector on the AB PLC. I have a sample of a CUI connector coming to check fit. I noticed that folks here seemed to indicate a standard 8 pin conn will fit... just not as well as the "special" AB connector.
Does anyone know if a standard 8 pin connector will fit the port??
Also, AB sells several cables. The 1763-NC01 is nice but the connector block is huge. The rest seemed to be wired for RS-232 and do not have conductors on pins 1 and 8... the two needed for RS-485 comms.
Optimally, I would like to find a prebuilt 8 pin cable with leads on one end that we can terminate with our own connector
Any help or hints would be appreciated. I have a strong desire to learn as much as possible about automation. I am grateful to have found this site.
Thanks so much!
