Product Description:

The BRKA04-0 cable is produced by B & R Automation and belongs to the 8BC ACOPOS Cables series. It serves as a dedicated serial link between programmable logic controllers and BRMEC mass-memory modules, allowing archived recipes or stored data to move reliably within machine-level automation. By matching the physical and electrical requirements of the controller ports, it provides a ready-made harness and helps prevent wiring errors when legacy RS232 devices are connected to modern PLC bases. This arrangement supports reliable communication between storage hardware and the control platform during routine data handling.

The link adheres to the RS232 interface standard, so it uses asynchronous serial communication that remains compatible with diagnostic terminals or standard COM ports. A length of 1.5 m keeps the connection manageable while still reaching from a cabinet-mounted PLC to an adjacent memory cartridge. Its short reach also helps keep the cable easy to route inside compact control cabinets. On the controller end, the cable terminates in a 25-pin D-type (M) shell that seats in the IF3 port with shielding to reduce crosstalk. The peripheral end uses a 9-pin D-type (M) connector fitted to the BRMEC board to minimize panel cutouts. The assembly is used for PLC to BRMEC mass-memory transfers, so the wire assignments match the handshaking required for file access commands.

The conductors inside the jacket follow the controller pinout, with the PLC side assigned as 2 RXD, 3 TXD, 6 DTR, 7 GND, 20 DSR. Corresponding positions on the memory module follow 1 GND, 2 DTR, 3 TXD, 4 RXD, 9 DSR, so the receive, transmit, handshake, and reference paths line up correctly between both ends. That layout supports stable hardware flow control and preserves the expected signal direction at each connector. The cable is intended for controller frames listed as PIF3/IF3, PP60, NTCP6#, and it connects directly to the BRMEC mass-memory side without jumpers or null-modem adapters. Terminated shields also help reduce crosstalk during serial data exchange.
