IKB0053 by Bosch Rexroth Indramat

The IKB0053 is an interface cable in the IKB Bus Cables series from Bosch Rexroth Indramat. It links a personal computer to a VCP operator panel so application data can be transferred when setup or diagnostics are required. In normal machine operation, the cable is typically used as a temporary connection rather than a permanent cabinet cable, which keeps the standard bus wiring separate from occasional PC access. This role makes it suitable for parameter transfer, panel communication, and other short-term connection tasks where a direct serial link is needed between the computer and the operator interface.

This cable uses the RS232 serial standard for point-to-point communication. Each end is fitted with a D-Sub 25 screw-lock connector, and both connector housings carry the code INS0520/L01 on both ends. The cable uses male contacts on both ends, so it mates with female panel or adapter connectors. Internal wiring includes all 25 pins, allowing the link to carry the full set of serial data, handshake, and auxiliary lines used by compatible devices. The screw-lock connection also helps keep the plugs seated during operation, which is useful when vibration or panel movement could loosen an unsecured serial cable.

Its assigned function is Download (PC-to-VCP), which indicates that the cable is intended for direct data transfer from a computer to the operator panel. A supported forwarding mode also allows communication to pass through the VCP while the connection is active, so the communication path can remain available to the next device in the chain. The assembly is supplied as a pre-built cable assembly, so no manual termination is required before connection. This avoids connector assembly work and keeps the pin arrangement consistent each time the cable is used. The result is a ready-to-connect serial cable intended for temporary access between a PC and a VCP panel without altering the standard machine wiring.
