Moxa UPort 2210 [21/36] Port settings

UPort 2000 Series Driver Installation

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 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.
