The Ports Configuration page settings are described below.
Port Settings
Auto Enumerating COM Number
If the “Auto Enumerating COM Number” checkbox is checked, COM numbers will be assigned automatically and
in sequence to the ports. E.g., COM3 to Port 1, COM4 to Port 2, etc.
If you do not enable this check box, only the first COM Number will be changed to new COM number list in the
drop-down list box. Enable this function if you want to configure several ports with sequential numbers.
Friendly Name
Setting Factory Default Necessity
1 to 20 characters
(E.g., UPort 1610-8)
Moxa UPort COM Optional
Use the “Friendly name” to allow easy identification of the serial devices that are connected to the UPort’s serial
ports.
UART FIFO
Enable/Disable Enable Required
The UPort’s serial ports provide a 128-byte FIFO both in the Tx and Rx directions. Disable UART FIFO setting
when your serial device does not have a FIFO to prevent data loss during communication. For a slow serial
device, we recommend you disable FIFO to improve the latency. If you want to use XON/XOFF flow control, we
recommend disabling UART FIFO.
