UPort 1200/1400/1600 Series User’s Manual Driver Installation

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	MOXA UPort COM	Optional
(E.g., UPort 1610-8)

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.
