UPort 1200/1400/1600 Series User’s Manual Driver Installation
2-15
The Ports Configuration page settings are described below.
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
Friendly name is specially designed to allow easy identification of the serial devices that are
connected to UPort’s serial port.
UART FIFO
Setting Factory Default Necessity
Enable/Disable Enable Required
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.
