APCI-7500-3/4C – DAQ PCI Card – Serial communication
The APCI-7500-3/4C interface is available as 4-port version. It is configured by inserting MX modules in the following modes: RS232, RS422, RS485 and 20 mA current loop, which the board identifies automatically. The modes can be freely combined. The interface is supported through a 128-byte FIFO buffer for sending and receiving data and guarantees reliable operation at high transfer rates.

The APCI-7500-3/4C communication card is configured by inserting MX modules which the board identifies automatically. The 4-port interface APCI‑7500-3/4C can be used as universal PCI boards in 3.3 V or in 5 V systems, and in PCI or PCI-X systems. The interface can be configured through modules in the following modes: RS232, RS422, RS485 and 20 mA current loop (with optical isolation). The MX modules with optical isolation allow a protection of up to 1000 V for the use in noisy environments where ground loops can occur. The I/O lines are protected against short-circuits, fast transients, electrostatic discharge and
high-frequency EMI. The interface is supported through a 128-byte FIFO buffer for sending and receiving data and guarantees reliable operation at high transfer rates.
