System overview
CX2550-0x79 system module USB extension
The CX2550-0x79 systems modules are attachments for the CX2000 Embedded PC series. They transmit
USB signals via a CAT 5e cable over distances of up to max. 50 m. The CX2550-0179 system module
transmits USB signals according to the USB 1.1 standard (full speed, max. 12 Mbit/s) while the
CX2550-0279 system module transmits USB signals according to the USB 2.0 standard (high speed, max.
480 Mbit/s). Both modules can be attached at the right-hand side of a CX20x0-CPU and are placed between
the power supply unit and the CPU. The internal connection is made via a USB port of the CX20x0-CPU; this
way, no PCI Express resources are required or used. No additional drivers are required for operation since
signal transformation and forwarding of the USB signals take place at the electrical level and are completely
transparent for the operating system.
The CX2550-0179 and CX2550-0279 modules enable the direct connection of Beckhoff Control Panels with
USB Extended interface. The CX2550-0179 system module is suitable for the connection of the Beckhoff
CP69xx and CP79xx Control Panel series with USB Extended 1.1 connection. The CX2550-0279 system
module is suitable for the connection of the Beckhoff CP29xx and CP39xx Control Panel series with USB
Extended 2.0 connection.
