2.5.6 Configurable Serial Interfaces

There are nine configurable Serial Interfaces available on the FDL-978 Series: Six UART style
Serial Port Interfaces (Ports 1, 2, 3, 4, 5, and 6), two ARINC 429 Input Interfaces (429 IN1 and
429 IN2), and one ARINC 429 Output Interface (429 OUT1).
Refer to Section 3.3.2 for detailed Serial and ARINC port configuration
information.
2.5.6.1 Serial Ports – RS-232/RS-422
Six UART style Serial Ports are available on the FDL-978 Series:
Serial Port 1
Serial Port 2
Serial Port 3
Serial Port 4
Serial Port 5*
Serial Port 6**
The Serial Ports can be software configured for various protocols and baud rates.
Refer to Section 3.3.2 for detailed information about serial and ARINC port
configuration.
*Serial Port 5 is not available on the 87098-00 and 87098-10 Transceivers.
**Serial Port 6 can be optionally configured for RS-232 serial interface on pins
J1-8 and J1-38.
The UART style Serial Interface pin connections are as follows:
