Product Description:
The 5AC600.485I-00 is a serial communication expansion board produced by B&R Automation for controllers in the 5AC CNC Addon Modules series. The board is inserted in a spare slot of a PC-based CNC system and supplies an additional asynchronous channel so that machine tools can interface with handheld terminals, sensors, or field service laptops. Within an automation cabinet, it removes the need for external converters, allowing the central processor to supervise ancillary equipment through direct software access.
The communication line leaves the module through a 9-pin male D-sub connector, a common plug format that simplifies cable assembly. On system boot, the hardware maps itself to the I/O address 2E8h, keeping it clear of COM1 and COM2 ranges and reducing address conflicts. Hardware interrupts are issued on IRQ10, which lets the processor service incoming characters with minimal latency even when other high-priority tasks run. A receive-and-transmit FIFO depth of 16 bytes lowers the frequency of interrupt requests by grouping characters, which is useful when long parameter strings are exchanged during program downloads. Signal lines are galvanically isolated, so ground potential differences between the CNC cabinet and the external device cannot create current loops that might corrupt data.
The interface mode can be switched among RS-232/RS-422/RS-485, and the module selects the correct transceiver direction through an automatic control scheme; no jumpers or software toggling are required when moving between point-to-point and multipoint wiring. Once configured, the embedded UART, which is 16550 compatible, supports standard driver libraries and offers hardware buffering for DMA-based transfers. The channel sustains line speeds up to 115 kbit/s, which is adequate for uploading part programs, transmitting diagnostic traces, or streaming positioning feedback from standalone axes.
