OnRISC configuration utility provides following features to configure OMAP3 based devices:
configure serial interfaces (RS232, RS422 etc.)
configure OTG/CFast switching
configure RTC
configure digital I/O
get EEPROM info
set MACs from EEPROM
B.1. Configure Serial Interfaces
Both VS-860 and Alekto2 provide two UARTs working in RS232/RS422/RS485 modes. Invoking
onrisctool.py without parameters will show which mode each port is configured to:
Port 1: mode control: DIP-switch
Port 1: mode: rs232
Port 2: mode control: DIP-switch
Port 2: mode: rs232
As one can see both port are configured in RS232 mode through DIP-switches. To switch the first
port into RS422 mode execute:
onrisctool.py -t rs422 -p 1
All possible modes are show in the Table 8
Mode Description
dip DIP-switch settings are valid

rs422 RS422
rs422-term RS422 with termination
