Connecting RS485 devices to X9

Qualified person

Requirements:

  • The same baud rate (1200 baud, 9600 baud or 19200 baud) must be set in all RS485 devices.

  • The connection cable is prepared for connection to the multipole connector ( > Preparing the Connection Cable).

Procedure:

  1. Connect the connection cable to the RS485 device (see the manual from manufacturer).
  2. Remove the sheath from the connection cable.
  3. Fold the surplus cable shield back over the cable sheath.
  4. Strip the insulation off the wires.

  6. If the product is at the beginning or end of the RS485 bus, install a jumper wire as a line terminator between pin 5 and pin 6 on the six-pole connector.
  7. Plug the 6-pole connector into the socket X9 on the product. Observe the pin assignment.
  8. Ensure that the connector is securely in place.
  9. Ensure that all conductors are correctly connected.
  10. Ensure that the conductors sit securely in the terminal points.
  11. Fit the cable shield onto an external shielding clamp.
