Communication connections
The device uses the serial ports for console or application communication, the
Ethernet port for network communication and cellular connectivity for wireless
applications.
3.1.1
Serial ports
The device has two application serial ports. Serial port 1 is configurable to either
console or data mode and supports RS-232 only. Serial port 2 is configurable to
multiple serial modes (RS-232/422/485). Serial port connectors are 9-pin D-sub
male connectors. Serial ports function as DTE devices.
3.1.1.1
Console/serial port 1
The console switch enables or disables console access. When the switch is in the
right position, serial port 1 is in the serial port mode, and when it is in the left
position, serial port 1 is in the console mode.
The console switch is located below the serial port 1 connector. Turn off power
from the device before toggling the console switch, as the switch position is read
during the boot sequence only. The baud rate is fixed to 115200 bps when the port
is configured in the serial console mode.
