Product overview
Embedded PC 29
 CX1020-N010 DVI / USB Module
 CX1020-N020 Audio interfaces
 CX1020-N030/40 serial interface for RS323

CX1020-N031/41 serial interface for RS422 / RS485
 CX1020-N060 Ethernet-interface
The CX1020-N010 option can be connected to Beckhoff Control Panels or standard monitors with DVI or VGA input
via the DVI or USB interfaces.Devices such as printer, scanner, mouse, keyboard, mass storage, CR-RW etc. can be
connected via the USB 2.0 interfaces. Multimedia capability is realized via the CX1020-N020 audio interface. The
modules CX1020-N030 and CX1020-N040 offer a total of four serial RS232 interfaces with a maximum transfer
speed of 115 kbaud. These four interfaces can be implemented in pairs as RS422/RS485, in which casethey are
identified as CX1020-N031 and CX1020-N041 respectively.The system interfaces cannot be retrofitted or expanded
in the field. They are supplied ex factory in the specified configuration and cannot be separated from the CPU
module. The system interfaces run through the internal PC104 bus, so that further CX components can
be connected. The power supply of the system interface modules is ensured via the internal PC104 bus.
