Default Port Settings; Setup For At Commands - Sierra Wireless FX30S User Manual

Rev 2 Mar.18
By default, the RS-485 termination resistor is disabled. To enable or disable the
RS-485 termination resistor, use the following Linux command:
./rs485.py /sys/devices/platform/msm_serial_hsl.0/
rs485_term <NEW MODE>
Where <NEW MODE> is either:
· 0—RS-485 termination resistor is disabled (drives GPIO63 high; the termi-
nation resistor is active low) (default)
· 1—RS-485 termination resistor is enabled (drives GPIO63 low)
For example, to enable the RS-485 termination resistor: ./rs485.py /sys/
devices/platform/msm_serial_hsl.0/rs485_term 1
To query the termination resistor status, use:
./rs485.py /sys/devices/platform/msm_serial_hsl.0/
rs485_term
which will return either DISABLED or ENABLED.
To make the rs485.py script executable, use the following command:
chmod a+x rs485.py
