UART Headers
The conga-IA5 provides two UART headers (X24, X25) via a Super IO (NCT6102D). The UART ports can be used under Windows 10 and Linux
without a special driver. UART header X24 (COM 0) fully supports RS-232. UART header X25 (COM 1) supports RS232 (Rx and Tx only), RS422
and RS485. Optionally, UART header X25 can be used for ccTalk instead.

Note
The conga-IA5 offers an optional ccTALK interface. This interface uses transmit and receive signals of COM 1. If this option is implemented,
COM 1 will not be available. congatec offers cables for the COM ports (see section 1.2.2 “Optional Accessories"). For more information,
contact congatec technical solution department.
