UPort 2000 Series User’s Manual Driver Installation

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 COM number for the selected port will be changed to

the COM number listed in the drop-down list box. Enable this function if you want to configure

the UPort’s serial ports with sequential COM numbers.

Friendly Name

Setting Factory Default Necessity

1 to 20 characters

(E.g., UPort 2210)

Moxa UPort COM Optional

Users can assign a Friendly name to each of the UPort 2000’s serial ports. The friendly name

gives users an easy way to identify the serial devices connected to the UPort’s serial ports. If you

enable set the change to all ports and then click OK, the same friendly name will be assigned to

all ports.

Fast Flush

Setting Factory Default Necessity

Enable/Disable Enable Required

The Fast Flush setting is designed for applications that call the Win32 PurgeComm() function

before reading or writing data. If Fast Flush is not enabled, then instead of just flushing the local

buffer, the UPort’s driver will query the UPort’s firmware repeatedly in a short period of time to

make sure that no data is queued in the UPort’s firmware buffer. For this reason, you may find that

your PC’s native COM ports respond much more quickly when making PurgeComm() function

calls compared to the UPort’s serial ports. In this case, enable Fast Flush (enabled by default) to

speed up the reaction of the UPort’s serial ports.
